How to Get a Construction-to-Perm Loan on Your Spec Home in 2026

You’ve found the lot. You’ve run the comps. The numbers work. But when you walk into the bank and say “spec home,” the loan officer goes quiet. Then they say something about “owner-occupied only” or “we’d need presales.”

Banks and spec homes have never been friends. If you’re a builder or real estate investor trying to finance ground-up construction on a property you plan to sell, traditional lenders will make you jump through a dozen hoops — and most of the time, still say no.

Construction-to-perm loans change the game. This guide breaks down exactly how they work, what lenders actually look for, and how to close faster with private and bridge lending options. If you’re ready to get funded now, apply in 2 minutes at slatefinancial.io/apply.

What Is a Construction-to-Perm Loan?

A construction-to-perm loan (also called a “one-time close” or “single close construction loan”) combines two financing phases into a single loan:

• Phase 1 — Construction Phase: You draw funds in stages as the build progresses. You typically pay interest only on amounts drawn.
• Phase 2 — Permanent Phase: Once construction is complete, the loan automatically converts to a standard term loan (or, in some private programs, you refinance out).

The key advantage: you close once, pay one set of closing costs, and avoid scrambling for a take-out loan mid-build when rates may have shifted.

For spec home builders specifically, the structure matters because your timeline from ground-break to sale is everything. A construction-to-perm loan keeps capital available throughout the build without requiring you to close twice.

Spec Home vs. Primary Residence: Why Lenders Treat Them Differently

Banks love construction loans for primary residences because they know the borrower will live there. The incentive to complete the build is obvious.

Spec homes — properties built with the intent to sell — look different to underwriters:

• No committed end-buyer at close
• Market risk if values shift during the build window (typically 6-18 months)
• Builder may walk away if economics deteriorate

Banks respond to this risk by requiring presales, large reserves, or denying outright. Private lenders and bridge lenders, however, underwrite to the deal — not the borrower’s life plans. They care about your exit strategy, the ARV (after-renovation or after-completion value), your experience as a builder, and your equity stake.

How Construction-to-Perm Draw Schedules Work

Whether you use a bank or a private lender, virtually every construction loan funds in draws tied to completed milestones. A typical schedule looks like this:

1. Closing Draw (10-15%): Released at loan close to cover initial site prep, permits, and mobilization costs.
2. Foundation Draw (10-15%): Released once foundation is poured and inspected.
3. Framing Draw (15-20%): Walls up, roof framing complete.
4. Rough Mechanicals Draw (15%): Plumbing, electrical, HVAC roughed in.
5. Drywall / Insulation Draw (10%): Interior walls enclosed.
6. Finish Draw (10-15%): Flooring, cabinets, fixtures installed.
7. Final / Certificate of Occupancy Draw (remaining balance): CO issued, punch list complete.

Private lenders typically require an independent draw inspection before releasing each tranche. Plan for 3-5 business days per draw request once the inspection is submitted.

The faster you build, the lower your total interest carry. Experienced spec builders often target 9-12 months from close to sale to minimize holding costs.

What Lenders Look For on a Spec Construction Loan

Private construction lenders underwrite to different criteria than banks, but they’re not handing out money blindly. Here’s what you’ll need to demonstrate:

1. Skin in the Game (LTC and LTV)

Most private lenders will fund 70-80% of total project cost (loan-to-cost, or LTC), which typically means 60-70% of the completed value (LTV). If your total project cost is $400,000 and the completed home will appraise at $575,000, a lender at 75% LTC would fund $300,000. You bring the remaining $100,000 plus all soft costs. Funding is subject to lender approval and appraisal.

2. Experience Track Record

First-time spec builders face higher scrutiny. If this is your first ground-up build, come prepared with detailed comp analysis, a licensed GC with a strong portfolio, and a conservative timeline. Experienced builders — even 2-3 prior spec projects — unlock better LTC ratios and faster approvals.

3. ARV Appraisal

Lenders need an independent “as-complete” appraisal showing what the finished home will be worth. Work with a local appraiser who knows the comp set. A strong ARV is the single most powerful piece of your loan package.

4. Exit Strategy

Your exit strategy is your repayment plan. For spec homes, the exit is typically a sale. Lenders want to see active comps within the last 90 days at or above your projected sale price, realistic days-on-market assumptions, and confirmation you’re not building a $700K home in a $500K neighborhood.

5. Budget and Timeline

A detailed construction budget broken down by trade, signed GC contract, and build timeline are non-negotiable. Cost overruns are the number one reason spec builds fail — lenders know this and will scrutinize your numbers closely.

Private vs. Bank Construction-to-Perm: The Real Comparison

Private lenders cost more per year, but speed and flexibility often make the math work. A deal that closes in 14 days instead of 90 days can mean the difference between landing the lot and losing it to a cash buyer.

Common Mistakes Spec Builders Make With Construction Financing

Underestimating Soft Costs

Permits, surveys, architectural plans, engineering, inspections, and lender fees are not in your hard construction budget — but they add up to 8-15% of total project cost. Leave room for them.

Using the Wrong Loan Product

Some builders try to fund spec homes with fix-and-flip bridge loans designed for renovations, not ground-up builds. These products typically don’t cover full construction draws and can leave you short mid-build. Make sure the product you’re using is explicitly structured for new construction.

Skipping the Interest Reserve

Many private construction loans allow you to roll 6-12 months of interest payments into the loan itself (an “interest reserve”). This preserves cash flow during the build. Ask for it upfront — retrofitting it after close is difficult.

Choosing the Cheapest GC Over the Most Reliable

A GC who comes in 15% under bid and then goes dark in month 4 will cost you more in delay interest and change orders than you ever saved. Lenders vet GCs too — bring a contractor with a proven track record on comparable builds.

Bottom Line

Construction-to-perm loans are one of the most powerful tools in a spec builder’s financing stack — and one of the most underused, because most builders assume they can’t qualify. The reality is that private lenders fund strong spec deals every week based on deal quality, not bank-style credit profiles.

The key is understanding what lenders need to see: solid ARV, realistic budget, experienced GC, skin in the game, and a clean exit. Bring those five things to the table and you’ve got a fundable deal.
