Construction to Permanent Loan New Hampshire | One-Time Close Financing
If you are planning to build a home in New Hampshire, a construction to permanent loan is a single financing solution that covers the land purchase (if needed), the cost of construction, and the permanent mortgage, all in one loan. Instead of taking out a separate construction loan and then refinancing into a standard mortgage once the home is finished, a construction to permanent loan rolls both phases into one closing. That means one application, one set of closing costs, and a seamless transition from the building phase to long-term homeownership.
New Hampshire buyers exploring this option are often choosing to build because existing inventory does not meet their needs, particularly in areas like Belknap County's Lakes Region, the Seacoast and southern commuter corridors of Rockingham County, and the Concord-area communities across Merrimack County. In each of these markets, buyers frequently need to finance a lot and construction together, making a one-time close construction loan a practical fit.
If your project involves renovating an existing home rather than building from the ground up, a different set of loan programs applies. NextGen's guide to renovation loans in New Hampshire covers those options in detail. This article focuses specifically on new construction financing.
One-Time Close vs. Two-Time Close Construction Loans
Before choosing a construction loan structure, it helps to understand how the two main approaches compare. The table below breaks down the key differences.
For most New Hampshire buyers building a primary residence, a one-time close construction loan is the simpler path. It removes the uncertainty of qualifying for a second loan after the home is built, and it eliminates exposure to rate changes during what can be a lengthy construction period. To understand how rate locks work and why the timing matters, NextGen's rate lock guide is a useful companion read.
How the Construction Phase Works
During the construction phase, you do not receive the full loan amount at once. Instead, funds are released through a draw schedule, a series of disbursements tied to construction milestones. Each draw is typically tied to the completion of a defined stage of work, such as foundation, framing, mechanical systems, and final finishes [verify typical lender draw schedule].
Before each draw is released, the lender orders an inspection to confirm that the work described in the draw request has been completed. Your builder submits the draw request, the inspector verifies the work, and the lender releases funds to cover that stage.
During this phase, you make interest-only payments based on the amount that has actually been drawn, not the full loan balance. Early in construction, when only a small portion of the loan has been disbursed, your monthly payments are relatively low. They increase as more draws are released and the outstanding balance grows.
This structure protects both you and the lender. It ensures that construction is progressing according to plan before additional funds are released, and it keeps your carrying costs lower during the months when the home is not yet livable. Understanding your full debt-to-income ratio before entering the construction phase helps you plan for these payments alongside any existing housing costs.
How the Loan Converts to a Permanent Mortgage
Once construction is complete, the loan converts from the interest-only construction phase to a fully amortizing permanent mortgage. This conversion is triggered by two events: the issuance of a certificate of occupancy from the local municipality and a final inspection confirming that the home meets the specifications outlined in the original plans and appraisal.
With a one-time close loan, the conversion is administrative rather than transactional. There is no second application, no second underwriting review, and no second set of closing costs. The permanent mortgage terms, including the interest rate, loan term, and monthly payment structure, were established at the original closing. Your payments simply shift from interest-only on the drawn balance to standard principal-and-interest payments on the full loan amount.
By contrast, a two-time close structure would require you to go through the full mortgage application and underwriting process a second time, with no guarantee that rates, your financial situation, or lending guidelines will be the same as when construction started.
Eligibility Requirements in New Hampshire
Construction to permanent loans have stricter qualification standards than a standard home purchase mortgage. Lenders are taking on additional risk by financing a property that does not yet exist, so the requirements reflect that.
Down payment. Construction loans typically require a larger down payment than conventional purchase mortgages. Expect to bring more to the table than the standard minimums you may have seen for existing-home purchases [verify current construction-to-permanent down payment minimum]. If you are exploring ways to supplement your down payment, NextGen's guides on gift funds for down payment and New Hampshire down payment assistance programs cover additional options worth reviewing.
Credit score. Lenders generally set a higher credit score floor for construction financing than for a standard mortgage [verify current construction-to-permanent minimum credit score]. If you are unsure where you stand, NextGen's overview of credit score requirements for a mortgage provides context on how different score ranges affect your loan options.
Builder requirements. Most lenders require that your builder be licensed, insured, and approved by the lender before the loan closes. The builder will typically need to provide a fixed-price contract, proof of insurance, references, and sometimes financial documentation [verify builder approval requirements]. This is not a formality. The lender is relying on the builder to deliver a finished home that matches the appraised value, so the vetting process is thorough.
Debt-to-income ratio. As with any mortgage, your DTI ratio plays a central role in qualification. Lenders will evaluate whether you can handle both the interest-only payments during construction and the fully amortizing payments once the loan converts.
Financing Land and Construction Together in NH's Growing Areas
One of the most common scenarios in New Hampshire's active building markets is a buyer who has found a lot but does not yet own it. In Belknap County's Lakes Region, Rockingham County's Seacoast communities, and the Concord-area towns of Merrimack County, limited resale inventory pushes more buyers toward new construction, and that often starts with purchasing land [verify current NH new construction/permit data].
A construction to permanent loan can include the land purchase as part of the total loan amount. Instead of taking out a separate land loan, waiting, and then applying for a construction loan, the entire transaction, lot acquisition and home construction, is financed under one closing.
If you already own the land, the equity you have in the lot can often count toward your down payment. This is a significant advantage for buyers who purchased land months or years before deciding to build.
Without a construction to permanent loan, financing a new build on purchased land typically requires three separate transactions: a land loan, a construction loan, and finally a permanent mortgage refinance. Each comes with its own closing costs, qualification requirements, and rate risk. The one-time close structure eliminates that complexity.

Construction to Permanent vs. Renovation Loans: Which Fits Your Project
The simplest way to decide: if you are building a new home on vacant land or after a teardown, a construction to permanent loan is the right structure. If you are buying an existing home that needs significant repairs or upgrades, a renovation loan is the better fit.
Renovation programs like the FHA 203(k) and Fannie Mae HomeStyle Renovation loan are designed for projects where a livable structure already exists. They roll the purchase price and renovation costs into one mortgage, but they are not built to handle ground-up construction from a vacant lot.
Construction to permanent loans, on the other hand, are specifically designed for new builds. They accommodate the draw schedule, builder approval process, and extended construction timeline that renovation loans do not.

Frequently Asked Questions
What is the difference between a one-time close and a two-time close construction loan? A one-time close construction loan covers both the construction phase and the permanent mortgage in a single closing. A two-time close requires two separate closings: one for the construction loan and a second to refinance into a permanent mortgage after the home is built. The one-time close approach saves a full set of closing costs and removes the risk of rate or qualification changes between closings.
Do I need to already own the land to get a construction to permanent loan in New Hampshire? No. A construction to permanent loan can include the land purchase as part of the total financing. If you already own the lot, the equity in your land can often count toward the required down payment. Either scenario works within the one-time close structure.
How much down payment do I need for a construction to permanent loan? Construction loans typically require a higher down payment than standard purchase mortgages because the lender is financing a property that does not yet exist [verify current construction-to-permanent down payment minimum]. Your specific requirement will depend on the lender, the loan program, and your overall financial profile. NextGen shops across multiple lenders to find the best fit for your situation.
What happens to my interest rate when construction is finished and the loan converts? With a one-time close loan, your permanent mortgage rate is typically locked or structurally defined at the original closing. When construction finishes and the loan converts to a permanent mortgage, the rate terms you agreed to at closing remain in place. With a two-time close loan, the permanent rate is not set until the second closing, which means your rate depends on market conditions at that future date.
Can I use any builder, or does the lender need to approve them? Most lenders require that the builder be licensed, insured, and formally approved before the loan closes. The lender will review the builder's credentials, financial stability, insurance coverage, and contract structure [verify builder approval requirements]. This protects you and the lender by ensuring the builder can deliver the project as planned.
How long does the construction phase typically take before the loan converts to a permanent mortgage? Construction timelines vary based on the size and complexity of the home, weather, permitting, and builder scheduling. Most single-family new construction projects take between 8 and 14 months, but lender-approved construction periods can range from 6 to 18 months depending on the loan program [verify typical construction phase duration by lender]. If construction runs beyond the approved period, extensions may be available but are not guaranteed.
Does NextGen fund the construction loan directly? No. NextGen Mortgage Loans is an independent mortgage broker, not a bank or direct lender. NextGen shops construction to permanent financing across multiple approved lenders to find the program, rate, and terms that best fit your project. This gives you access to options from multiple sources without applying separately to each one.
Can I get pre-approved for a construction to permanent loan before I have a builder selected? In most cases, you can begin the pre-approval process to understand your budget and borrowing capacity before finalizing a builder. However, full loan approval and closing will require an approved builder and a signed construction contract with detailed plans and specifications.
