What do lenders require for a construction loan?
Most construction lenders look for:
- A credit, income, and asset review, much like a regular mortgage
- Enough equity, from cash, land you own, or both. See how land equity works.
- An approved builder with a license or registration, insurance, and references. See builder approval.
- Plans, specifications, and a line-item budget, often with a contingency line
- An "as completed" appraisal of the lot and finished home together
- Title work, a survey, and insurance, including builder's risk during construction
- Reserves for cost overruns, depending on the lender
Requirements vary by lender and loan program. FHA, VA, USDA, and conventional loans each have their own rules.
Does my builder need a license in Delaware?
Delaware requires businesses, including contractors, to hold a state business license, which you can look up through the Division of Revenue (Delaware business license search). Building permits and code enforcement are handled by your county or municipality. Expect your lender to run its own builder review. See how builder approval works.
Ask your county or municipal permit office whether you can pull permits as an owner-builder. Many lenders won't finance an owner-builder. Read more about owner-builder construction loans.
Which building code applies in Delaware?
Delaware's building codes are adopted and enforced by each county or municipality, so the edition depends on where you build. Ask your county or town permit office which code applies and what inspections it requires.
Do I need a septic permit in Delaware?
If there's no sewer, yes. DNREC regulates on-site wastewater systems, including site evaluations and permits to install a new system (DNREC, septic systems). Lenders usually want the permit before the first draw.
What about flood zones in Delaware?
Check your lot on the FEMA Flood Map Service Center. If the home sits in a high-risk flood area, the lender will generally require flood insurance. Coastal lots can also face county and state rules, so ask your permit office early.
Do I need an attorney to close in Delaware?
Yes. Delaware requires a Delaware attorney to conduct real estate closings (Delaware Supreme Court, Office of Disciplinary Counsel digest). The realty transfer tax is due when the deed is recorded (Del. Code title 30, chapter 54).
How do mechanics' liens work in Delaware?
In Delaware, a contractor who deals directly with the owner generally must file a lien claim within one hundred eighty days after completing the work, and other claimants within one hundred twenty days after their last work or materials (25 Del. C. § 2711). Lenders collect lien waivers as each draw is paid.
Are there state homebuyer programs for building in Delaware?
The Delaware State Housing Authority (DSHA) offers homebuyer programs through participating lenders (DSHA). Ask whether a program can be used with new construction before you plan around one.
How do I check that a lender is licensed in Delaware?
Search the lender and loan officer on NMLS Consumer Access. The Delaware Office of the State Bank Commissioner licenses non-bank mortgage lenders, brokers, and loan originators (Delaware Office of the State Bank Commissioner).
What are the steps to build in Delaware?
- Confirm the lot can be built on: access, zoning, flood zone, and septic or sewer.
- Choose a qualified builder and get plans, specs, and a line-item budget.
- Compare lenders and get a Loan Estimate for your project.
- Apply. The lender reviews you, your builder, and the plans, and orders an appraisal.
- Get the DNREC septic permit (if needed) and the county or municipal building permit.
- Close with a Delaware attorney and record the deed and mortgage with the county recorder of deeds.
- Build. The lender pays the builder in draws after inspections. You pay interest on the money drawn so far.
- Pass the final inspection and get a certificate of occupancy.
- The loan converts to your permanent mortgage. See what happens at conversion.
