Overview of New Construction Mortgages

At the outset, it’s essential to distinguish a new construction mortgage from a traditional home mortgage. When you buy an existing home, a standard mortgage pays the seller the full purchase price, and you move in right after closing. However, with new construction, the property does not exist yet—or is unfinished—when you begin the process. This means that funds must be released over time, as construction progresses and milestones are completed.

The two main scenarios are:

• Building a custom home on your own lot/land (You hire a builder and custom-design the home.)
• Buying from a homebuilder in a subdivision (a “production” home, where you choose from set floor plans and options.)

Both scenarios usually involve a different mortgage process than existing homes, with overlapping but distinct types of construction loans and permanent mortgage options.

Types of Construction Mortgages

Understanding your financing options is the foundation of a successful new construction project. In the United States, there are several types of loans tailored to new construction:

1. Construction-to-Permanent Loans (“One-Time Close”)

In this option, you apply once and close a single loan that finances both construction and converts to a regular mortgage upon completion. The lender disburses funds to the builder in intervals (“draws”) during construction. Once the home is finished, the loan converts into a traditional mortgage with monthly payments.

• Pros: One closing costs package; Rate can often be locked in early; Simplicity and continuity.
• Cons: May be harder to qualify; Sometimes higher initial rates before conversion.

2. Construction-Only Loans (“Two-Time Close”)

Here, you first get a separate short-term construction loan (typically 6-18 months). When the house is completed, you apply for a regular mortgage to “pay off” the construction loan and finance the finished home.

• Pros: Potentially more flexible; May be easier to switch lenders if needed at conversion.
• Cons: Two closings and associated fees; Interest rate risk at time of permanent financing; More paperwork.

3. Builder or Subdivision Financing

Many large builders offer financing through affiliated lenders. In this scenario, the home is typically near completion before buyers obtain a traditional mortgage. The builder finances construction and you close on a standard mortgage at the end.

• Pros: Streamlined for standard plans; Builder may offer incentives or rate buydowns.
• Cons: Less flexibility in lender choice; May not work for fully custom builds or owner-managed projects.

4. Renovation/Construction-Plus Loans

These blend features of home renovation loans (such as the FHA 203(k) or Fannie Mae HomeStyle) but can also apply to some new construction situations, particularly where existing structures are modified or replaced.

Qualification Requirements

Lenders consider new construction to be inherently riskier than financing a completed home. Accordingly, the loan application and approval process tends to be more stringent:

Credit Score

Most lenders require a credit score of at least 680-700 for construction-to-permanent loans, though some government-backed programs may allow scores as low as 620. The higher your score, the broader your choices and better your terms.

Down Payment and Equity

You will typically need a minimum down payment of 20% (unless accessing FHA/VA/USDA programs), though some lenders may allow 10-15% with strong credentials. If you already own the land, your land’s equity can count towards your down payment requirement.

Income and Debt-to-Income Ratio (DTI)

Lenders will scrutinize your income history and DTI ratio. Generally, your total debts (including future housing payment) must not exceed 45% of your gross monthly income.

Builder Approval

Lenders not only vet the borrower—they must also approve your builder. This ensures the builder’s reputation, licensing, insurance, and track record meet lender standards, reducing default risk due to construction problems.

Appraisal and Project Assessment

Your lender will commission an “as completed” appraisal based on the plan, specifications, and location of your proposed home. This estimate of future value influences your loan-to-value (LTV) calculation and ultimately how much you can borrow.

Down Payments and Equity Contributions

Down payments for new construction loans are typically higher than for mortgages on existing homes. Here’s what you need to know:

Minimum Down Payment Requirements

• Conventional construction loans usually require at least 20% down.
• FHA Construction-to-Permanent loans may allow as low as 3.5% down but have stricter rules and higher mortgage insurance costs.
• VA and USDA loans may offer no down payment options for eligible borrowers, though other requirements apply.

How Land Equity Works

If you already own your building lot, most lenders allow the appraised value or the purchase price (whichever is lower) to be counted as your equity contribution. For example, if your land appraises at $100,000 and your total project cost is $400,000, you may only need to contribute $60,000 more to reach 20% down.

Builder Deposits and Earnest Money

Many builders require an upfront deposit to secure your contract and begin construction. These funds are typically credited toward your down payment and closing costs, but it’s vital to clarify whether these deposits are refundable and how they integrate into your mortgage process.

The Application and Approval Process

Securing a mortgage for new construction involves several detailed steps, more than a typical purchase mortgage. Here is what you should expect:

Initial Pre-Approval

Obtaining a pre-approval provides an early estimate of what you can borrow and demonstrates to builders you’re a serious buyer. This step reviews your credit, income, assets, and debts.

Submitting Plans and Specifications

Most lenders require:

• Complete architectural plans and building specifications
• Dated and signed construction contract with your builder
• Detailed cost breakdown (so-called “line item budget” or cost worksheet)
• Survey and legal description of the land

This documentation forms the basis for loan approval and appraisal.

Appraisal Process

The appraiser analyzes your plans, specs, and location to estimate the home’s future market value (“as completed”). The final loan amount cannot exceed a set percentage (LTV limit) of this appraised value or total cost, whichever is lower.

Lender Review and Approval

The lender’s underwriters scrutinize all submissions, including the builder’s credentials, budget, plans, and your personal finances. They will also approve the project schedule, insurance policies, and any additional documents required.

Initial Closing

Once approved, you close on your construction (or construction-to-permanent) loan. At this time, closing costs, loan origination, and some or all of your down payment must be paid.

Timelines and Construction Phases

One of the biggest differences between mortgages for existing homes and new construction is the loan’s timeline and staged funding:

Draw Schedules

Funds are not disbursed as a lump sum. Instead, the lender releases money from your loan in pre-arranged intervals (“draws”) as construction milestones are completed (e.g., foundation poured, framing, roofing, mechanicals, final finish).

Interest-Only Payments During Construction

Typically, during construction, you pay only interest on funds actually drawn/disbursed—not the total loan amount. Principal and interest payments on the full amount begin only after the home is finished and the mortgage converts to permanent status.

Project Timeline

• The usual construction period allowed is 6–12 months
• Lenders carefully monitor project progress to ensure timely completion
• Delays due to weather, inspections, permitting, or supply shortages may require loan extensions (sometimes with fees)

Extension and Change Order Policies

Many lenders will allow a limited extension if the project runs long (potentially at an additional cost or interest rate adjustment). Change orders—alterations to original plans—must be reported to the lender, and may require new underwriting if costs increase substantially.

Choosing and Assessing Builders

Your choice of builder directly impacts your ability to secure a mortgage, your overall experience, and the final quality of your home:

Experience and Credentials

• Lenders usually require builders to be licensed, insured, and have a strong track record
• Some lenders keep an “approved builder” list; others require you to submit the builder’s business documents, insurance, references, and financials for review

Contract Terms

• Clear, detailed contracts protect both you and your lender
• Contracts should specify costs, timelines, included features, payment schedules, and remedies for delays or disputes

Verifying Reputation

• Check online reviews, Better Business Bureau ratings, and local court records for past lawsuits or complaints
• Ask for and check references from prior clients with similar scope projects
• Confirm builder is properly licensed and insured in your state/jurisdiction

Builder Risk

Lenders may refuse financing if a builder has a poor financial condition, unfinished projects, or excessive complaints. Work only with reputable professionals to safeguard your investment and financing eligibility.

Inspections, Draw Schedules, and Disbursements

Lenders stake considerable funds on the proper completion of your home. To minimize risk, they institute controls that affect both you and your builder:

Draw Requests and Inspections

• To authorize each draw, lenders require an on-site inspection to verify that a specific phase is complete and meets quality standards
• This inspection is separate from code compliance or local permitting inspections; it’s for the protection of the lender and your project

Budget Monitoring and Change Orders

• Each draw must match the completed work and approved construction budget
• Significant change orders (cost or scope increases) must be communicated quickly to the lender, who may need to re-approve the project

Lien Waivers and Payment

• Builders or contractors usually must provide lien waivers (proof all subcontractors/suppliers were paid) before draws are released. This reduces the risk of future liens on your property due to unpaid bills

Final Inspections and Certificate of Occupancy

• A final inspection is required before the last draw is issued
• You must obtain a certificate of occupancy from your local jurisdiction confirming the home is fully completed and fit for residence

Interest Rates, Lock Options, and Closing Costs

Interest rates, rate lock policies, and costs for construction loans differ from traditional mortgage loans:

Construction Phase Interest

During the building process, you pay interest only on the funds that have already been disbursed. This means payments start low and increase as more of the loan is drawn for construction.

Rate Lock Policies

Rate locks can be complex. Some lenders allow you to lock in a permanent mortgage rate before construction, others only after. Long-term locks (180 days or more) may have higher rates or additional fees, but protect you from rising rates during the build.

• Ask about lock extension policies (in case of building delays)
• Carefully compare lender terms and options, as these can significantly affect your long-term cost

Closing Costs

• Expect higher closing costs for construction loans due to dual-phase underwriting, extra inspections, and more paperwork
• Pay attention to itemized title company fees, appraisal fees, inspection fees, insurance, origination charges, and builder’s deposit policies

Converting to Permanent Financing

When the house is finished, your lender must confirm completion, update paperwork, and, if necessary, convert the construction loan to permanent financing:

For Construction-to-Permanent Loans

• Often converts automatically once certificate of occupancy and final inspections are complete
• You begin making regular principal & interest payments on your full mortgage
• If you locked your rate at closing, your payment terms begin per original agreement

For Construction-Only Loans

• You must re-apply for a standard mortgage (possibly with a new credit, income, and appraisal check)
• There is a risk mortgage rates may have risen or your circumstances changed, affecting eligibility
• This “two closings” model can mean double closing costs

Title Updates and Final Policy Issuance

• Title insurance must be updated to reflect full ownership (free of builder or subcontractor liens)

Common Pitfalls, Delays, and How to Avoid Them

Many things can go wrong during new construction—from the minor to the catastrophic. Being proactive and informed is your primary defense:

Permitting and Zoning Problems

Ensure all necessary building, zoning, and environmental permits are in place before work begins. Delays due to permit denials or missed approvals can be costly.

Cost Overruns

• Have a detailed, signed contract and resist frequent or unnecessary upgrades (“change orders”)
• Set aside a contingency reserve (5–10% of budget) in case unexpected costs arise

Builder Financial or Performance Issues

• Thoroughly vet builder finances, reputation, and track record before signing anything
• Insist on performance bonds or verified insurance for major custom projects

Lien Risks from Unpaid Contractors

• Monitor builder for timely payment of subs and suppliers; insist on lien waivers before each draw
• Failure to procure necessary lien releases could leave you facing surprise legal settlements down the road

Market and Rate Fluctuations

• Interest rates could rise before you lock in or convert to a permanent mortgage
• Appraised values can drop if the broader real estate market weakens mid-project, complicating financing

Delays Due to Labor or Material Shortages

• Factor in buffer time for supply chain, weather, or labor shortage delays—especially in volatile times
• Communicate regularly with your builder about timeline expectations and potential risks to completion

Insurance, Title, and Legal Considerations

Protecting your investment is essential as construction progresses:

Builder’s Risk and Homeowner Insurance

• Builder’s Risk Insurance: Covers damage or loss to property/equipment during construction. Sometimes the builder provides it initially, then you take over prior to completion.
• Homeowners Insurance: Your permanent policy should be in effect before move-in. Notify your insurer of the construction phase for proper coverage.

Title Insurance

• Title insurance protects you from prior unresolved ownership claims, liens, or errors in legal description
• Require an updated title search at each draw, and especially before permanent loan conversion

Legal Protections and Contracts

• Have all contracts (with builder, architect, and lender) reviewed by a qualified real estate attorney
• Specify remedies for cost overruns, delays, and workmanship disputes
• Ensure the contract allows for all necessary inspections and lender verifications

Special Programs: FHA, VA, and USDA Construction Loans

Borrowers who do not meet the requirements for a conventional construction loan may have options with government-backed programs:

FHA Construction-to-Permanent Loans

• Available with as little as 3.5% down
• Strict documentation, FHA-approved builder required, and mortgage insurance premiums apply
• Limits on loan size according to area (“conforming limits”)

VA Construction Loans

• For eligible veterans and service members; sometimes possible with no money down, but fewer lenders offer these loans
• Stringent builder and contractor approval rules
• Only for primary residences

USDA Construction Loans

• For rural properties and income-eligible buyers
• No down payment required, but geographic and program restrictions apply

Note: Not all lenders offer FHA, VA, or USDA construction loans; finding experienced specialists is critical.

Custom vs. Production Homes: Mortgage Implications

Your mortgage pathway will be shaped by the kind of new home you choose:

Custom Home Construction (On Your Lot)

• You purchase the lot/land and hire an architect and builder to design/home to your specific needs
• You will need a construction loan and likely go through multi-phase closing
• You are more responsible for project oversight, change orders, and communications with lenders

Production/Tract Builders (Subdivision Homes)

• Builder owns the land; you select a pre-designed floor plan, often with standardized options
• You may only need to obtain a standard mortgage by closing, as the builder finances the project until the home is ready for occupancy
• Builder may offer incentives for using affiliated lenders, but check whether you’re getting the best deal

Financial Planning and Budgeting for New Construction

Building a new home is an expensive undertaking, made more manageable with disciplined financial planning and budgeting:

Cost Components

• Land acquisition and development (if not included by builder)
• Construction budget (labor, materials, permits, utility connections, landscaping)
• Soft costs (architectural, engineering, appraisal, permit fees, impact fees)
• Mortgage origination and closing costs
• Contingency reserves for overruns or upgrades

Sticking to the Plan

• Get detailed, fixed-price bids and contracts whenever possible
• Establish a process for approving and funding change orders—avoid unnecessary upgrades during construction
• Set aside an additional 5–10% of total budget for unplanned expenses

Managing Payments and Documentation

• Track all payments, invoices, and change orders carefully
• Maintain current insurance coverage at all times
• Request and retain all lien releases and proof of payment to subs/suppliers at each completed draw

Long-Term Affordability

• Consider future property taxes, insurance, homeowner association dues, and maintenance costs in your affordability analysis
• Make sure your finished home will appraise at or above your final cost—this preserves home equity and financing flexibility

Frequently Asked Questions

• Can I get a mortgage if my home hasn’t been started yet?
  Yes, but you generally need a construction loan that becomes a permanent mortgage after building is complete.
• Do I make full payments before the house is completed?
  No. During construction, you usually pay interest only on amounts drawn. Full monthly payments start after completion.
• Are construction loans harder to qualify for?
  Yes. They require a stronger credit profile, higher down payment, and more documentation than mortgages for existing homes.
• Can I act as my own builder/general contractor?
  Rarely. Most lenders require a licensed, experienced builder due to increased risk with “owner-builder” loans.
• How can I protect myself from construction delays?
  Insist on clear contract terms about penalties for delays, communicate regularly, and choose a builder with a strong track record.
• What happens if market values drop during construction?
  If the home appraises for less at completion, your financing options may be limited and you may need to provide additional funds to close.
• Can I use gift funds for my down payment?
  In many cases, yes—but documentation is required, and the rules vary by loan type and lender.

Conclusion

Securing a mortgage for new construction in the United States requires much more than just applying and waiting for approval. It is a multi-step journey full of unique procedures, from choosing a reliable builder and obtaining permits, through phased inspections, managing expenses and interest payments, to finally converting your construction loan into the mortgage that will finance your future in the home you build.

Paying close attention to the details—such as qualification and documentation requirements, builder selection, financial planning, draw schedules, and the legal nuances of contracts and insurance—is crucial to safeguard your investment, control costs, and avoid trouble. Coordination and communication between you, your builder, your lender, and your legal and real estate professionals will help you manage surprises and keep your construction—and your mortgage—on track.

Whether you’re building a custom home or buying new from a developer, being informed and prepared every step of the way is the key to success.
