If you’re buying a finished spec home, you’ll typically close on a new construction home 30 to 45 days after the builder is ready to hand it over. If the house is still being built for you, plan on four to six months for a semi-custom build and anywhere from ten months to well over a year for a fully custom one. Three events have to line up before closing can actually happen: the builder finishes construction, your local building department issues a Certificate of Occupancy, and your lender clears the loan to fund. Miss any one of those, and the date moves.
How the Type of Build Sets Your Timeline
The single biggest factor in when you close is what stage the home is in when you sign the contract.
- Spec or quick move-in homes are already built, or nearly so, when you commit to buying. Because the structure is essentially done, closing can happen in roughly 30 to 45 days, similar to a resale, once the mortgage process starts.
- Semi-custom homes let you pick a floor plan and finishes while the builder controls the schedule. Expect four to six months from contract to closing, sometimes longer when permits or materials slip.
- Fully custom builds, where you own the lot or the builder starts from scratch for you, routinely take ten months to over a year. Design complexity, site conditions, and local permitting speed all push the number.
Knowing which category you’re in shapes everything that follows, especially how long you need to protect your mortgage rate.
The Certificate of Occupancy Is the Legal Trigger
Your local building department issues a Certificate of Occupancy after inspections confirm the home meets building codes and zoning requirements. Inspectors check the plumbing, electrical, structural framing, fire safety, and other systems before signing off. This document is what actually unlocks closing. Without it, lenders won’t fund the mortgage, because the property isn’t yet certified as safe to live in.
Some municipalities will issue a temporary or conditional Certificate of Occupancy when the home is substantially habitable but minor items like landscaping or a shared driveway’s final coat remain. Not every lender will close on a temporary certificate. Those that do often require an escrow holdback, money set aside at closing to make sure the remaining items get finished. Ask your lender early whether a temporary certificate is acceptable, so you aren’t surprised the week you expect to move in.
Substantial Completion and the Short Window to Close
Substantial completion means the home is functional for its intended use even if minor cosmetic work remains. Once the builder hits that point, they typically send a formal notice that starts a short closing window written into your contract, sometimes as few as ten days. Missing it can trigger per diem charges, which are daily fees the builder assesses to cover their carrying costs, and in some contracts your earnest money is at risk.
Read the specific delay and completion language in your purchase agreement long before construction wraps. If you aren’t fully approved and ready to fund when the notice hits, those ten days vanish quickly.
Protecting Your Mortgage Rate Across a Long Build
Standard mortgage rate locks run 30 to 60 days. That’s fine for a resale, and roughly workable for a spec home, but it’s far too short for a semi-custom or custom build. You need a strategy to hold your rate across the construction period.
- Extended rate locks ranging from 90 to 360 days are built specifically for new construction. Longer locks cost more, usually an upfront fee calculated as a percentage of the loan amount, but they shield you from rate increases while the house goes up.
- Float-down options, offered on some extended locks, let you take a lower rate if the market drops before closing. The feature typically adds to the lock fee.
- Lock extensions let you push the deadline if construction runs long. Extension fees commonly run 0.25% to 0.50% of the loan amount each time.
A construction delay that pushes you past the lock can cost thousands in higher interest over the life of the loan. Budget the lock cost from the start, and ask your lender exactly what happens if the lock expires before the builder is done.
What Happens When the Build Runs Late
Delays are common. Weather, material shortages, permit backlogs, and subcontractor scheduling all push completion dates back. The financial exposure cuts both ways, but you need to know yours.
- Rate lock expiration is the big one. A delay forces you to pay for an extension or take whatever rate is available when you finally close.
- Updated loan documentation may be required if closing slips significantly. Your lender can ask for refreshed pay stubs, bank statements, or a new credit pull, and anything that’s changed in your financial picture can affect approval.
- Per diem charges in some builder contracts apply when the buyer causes the delay, such as failing to finalize financing on time. These usually reflect a fraction of the builder’s monthly carrying costs on the property.
- Builder penalties, in the form of liquidated damages, are a pre-agreed daily amount the builder owes you if they miss their deadline. These clauses aren’t standard. Negotiate them in before you sign, because if the contract is silent on builder-caused delays, your recourse may be limited to waiting.
Confirm in writing whether your earnest money is protected if the builder misses the deadline, and what costs fall to you if you aren’t ready to close when they finish.
The Appraisal on a Home That Isn’t Finished Yet
Your lender orders an appraisal to confirm the home’s value supports the loan, and for new construction the process has an extra step. If the house isn’t built yet, the appraiser performs a subject-to appraisal, estimating value based on the plans, specifications, and comparable sales, subject to construction being completed as described. Once the builder finishes, the lender may order a follow-up inspection, sometimes called a certificate of completion, where the appraiser returns to verify the home was built to those plans.
If the appraised value comes in below your purchase price, you can try to negotiate a lower price with the builder, cover the gap in cash, or walk away if your contract includes an appraisal contingency. Builders of spec homes in competitive markets sometimes resist price reductions, so know your contract rights before you need them.
The Final Walkthrough and Punch List
Before closing, you walk through the finished home with the builder’s representative and inspect every room, system, and fixture. The output is a punch list, a written record of defects or incomplete items. Common entries are cracked tiles, paint touch-ups, misaligned cabinet doors, missing trim, and dead outlets.
Record every issue on the builder’s punch list form and keep a copy. That document is a binding record of what the builder has agreed to fix after you take possession. For items that genuinely cannot be done before closing, like exterior landscaping in winter, your closing agent may set up an escrow holdback, holding money from the builder’s proceeds until the work is done. A typical holdback equals 1.5 times the estimated repair cost, and the builder usually has 30 to 90 days to complete the work before the escrow agent can use those funds to hire someone else.
Documents That Have to Be in Place Before You Close
The Closing Disclosure Three-Day Rule
Federal law requires your lender to deliver the Closing Disclosure, the final breakdown of your loan terms, monthly payment, and settlement charges, at least three business days before closing.1eCFR. 12 CFR 1026.19 – Certain Mortgage and Variable-Rate Transactions Certain changes after you receive it reset that clock: an inaccurate annual percentage rate, a change in loan product, or the addition of a prepayment penalty forces the lender to issue a corrected disclosure and restart the three-day waiting period.2Consumer Financial Protection Bureau. TILA-RESPA Integrated Disclosure FAQs A late change can push your closing date.
Homeowners Insurance
Your lender needs proof of a homeowners insurance policy before clearing you to close, and for new construction it should cover the full replacement value of the completed structure. Have your agent issue a binder, a temporary proof of coverage, and send it to your lender at least a week before closing. Insurance paperwork arriving late is one of the most common last-minute reasons closings slip.
Termite Soil Treatment Records
In areas with subterranean termites, lenders handling FHA or VA loans often require documentation of soil pretreatment before closing. The builder provides the guarantee, typically on HUD Form NPMA-99-A, certifying that treatment met federal and state requirements. If infestation occurs within one year of closing under the guarantee, the builder must arrange treatment and repair any resulting damage at no cost to you.3U.S. Department of Housing and Urban Development.

What Closing Day Itself Looks Like
The closing takes place at a title company or attorney’s office, depending on your state. A settlement agent walks you through signing the deed, the mortgage note, and the various disclosures. Some jurisdictions allow electronic signatures for most of the paperwork, though notarized documents may still require you to be there in person.
Funding happens through a wire transfer or certified cashier’s check for the exact amount shown on the Closing Disclosure. Once the lender reviews the signed documents, it releases the mortgage funds to the settlement agent’s escrow account. The agent distributes the money, paying the builder, title insurance, recording fees, and other third-party charges. After the builder has the full purchase price, you get the keys.
What Happens Right After You Close
Deed Recording
The title company or attorney submits your signed deed and mortgage to the county recorder’s office. That filing creates the public record that you own the property. You don’t have to do anything; a recorded copy will arrive by mail weeks later.
Builder Warranties Start Running
New construction homes typically come with a tiered builder warranty. According to the Federal Trade Commission, the usual structure is:
- One year on workmanship and materials for most components, including siding, doors, trim, drywall, and paint.
- Two years on heating, cooling, plumbing, and electrical systems.
- Up to ten years on major structural defects, generally defined as problems that make the home unsafe, such as a collapsing roof or a failing foundation.
Those periods start at closing, and activation is usually automatic once the deed is recorded.4Federal Trade Commission. Warranties for New Homes Read the warranty document so you know how to submit claims and what deadlines apply. Report defects as you find them. Waiting until the end of the coverage window to file a long list of issues complicates the process.
The Supplemental Property Tax Bill
Your first property tax bill after closing can be a shock. During construction, the land was likely assessed at its unimproved value, so the tax bill was low. Once the home is complete and ownership transfers, the county reassesses at the full improved value. In many areas that triggers a supplemental bill covering the difference, prorated from the completion date to the end of the tax year. It arrives separately from the regular annual bill and isn’t always built into your lender’s escrow projections. Budget for it. The jump from vacant-lot assessment to finished-home assessment can be substantial.
