What Happens to Your Loan if the Build Runs Over or Late?
If your build runs over budget, you usually cover the extra cost from your contingency or your own cash, or ask the lender to change the loan for documented cost increases. If it runs late, you may need a construction period extension, and some loan terms or documents may need updating before the loan converts.
For how to prevent overruns, see construction loan cost overruns. This post covers what happens to the loan itself.
Over budget vs. behind schedule at a glance
| Over budget | Behind schedule | |
|---|---|---|
| What the lender sees | Remaining loan money won't finish the house. | The build won't finish by the construction period end date. |
| First line of defense | Your contingency line in the budget. | A built-in extension option, if your loan has one. |
| If that's not enough | Bring cash, or request a loan change for documented costs. | Request an extension. Fees may apply. |
| Paperwork | Updated budget, change orders, signed bids. | Updated schedule from the builder, reason for the delay. |
| Possible side effects | New appraisal or requalifying. | Updated credit and income documents before conversion. |
When the build runs over budget
Lenders pay builders in draws, based on finished work. If what's left in the loan won't finish the home, most lenders pause draws until the gap is covered. That protects you and the lender from a house that stops halfway.
Your options usually look like this:
- Use your contingency. That's what it's for. Our contingency calculator helps you size one before you start.
- Bring cash. Many lenders want you to deposit the difference before the next draw.
- Cut scope. Swap finishes or remove items through a change order.
- Ask for a loan change. Fannie Mae's single-closing construction-to-permanent rules allow a larger loan amount only for documented higher construction costs. You'd still need to qualify for the new amount.
When the build runs late
Every construction loan has a construction period with an end date. Fannie Mae limits how long that period can run on a single-close loan, with extensions allowed. Lenders set their own rules too.
If you're running late:
- Ask early. Request an extension before the end date, not after.
- Expect questions. The lender will want an updated schedule and the reason for the delay.
- Ask about fees. Some lenders charge for extensions. Ask before you sign the loan, not mid-build.
- Check your locked terms. Ask what happens if you pass any deadline tied to the terms you locked.
Our construction loan timeline guide covers where builds usually slow down.
What happens at conversion
When the home is done, the loan converts to a regular mortgage. If the build ran long, a few things can change:
- Your documents may be too old. The lender may need new pay stubs, bank statements, and a credit report.
- You may need to requalify. If your income, debts, or the home's value changed, the lender re-underwrites.
- A final inspection is required. The lender confirms the home was built to the plans. See how a construction loan converts to a mortgage.
Frequently asked questions
Will my lender pay for cost overruns?
Not automatically. You usually cover overruns from your contingency or cash. Some loans can be increased for documented higher construction costs if you still qualify.
Can I extend my construction loan if the build is late?
Often, yes. Many lenders allow extensions, sometimes with fees. Ask early and bring an updated schedule.
Will a delay affect my loan terms?
It can. Ask your lender what happens if you pass any deadline tied to the terms you locked.
Do I have to requalify if the build runs long?
Possibly. If your documents are too old at conversion, or your finances or the home's value changed, the lender may requalify you.
What if I can't cover the overrun?
Talk to your lender and builder right away. Options include cutting scope, adding cash from another source, or a loan change if you qualify.
