Construction-to-Permanent Loans in 2026: The Spec Builder’s Guide to One-Loan Financing

You have the lot. You have the plans. You have a buyer lined up the moment the home is finished. What you do not have is a bank willing to fund the build and the permanent mortgage in one clean deal.

Construction-to-permanent loans are designed exactly for this situation. Instead of carrying two separate closings, two sets of fees, and two rounds of underwriting, you close once, draw funds during the build phase, and convert to a permanent mortgage when the certificate of occupancy is issued.

In 2026, these loans are available — but not from every lender, and not without knowing how to position your deal. This guide breaks down how construction-to-perm loans work, what lenders are actually looking for, and how spec builders in Florida, Texas, Georgia, and South Carolina are getting funded when banks say no.

What Is a Construction-to-Permanent Loan?

A construction-to-permanent loan (also called a one-time-close or OTC loan) combines two phases of financing into a single product:

• Phase 1 — Construction: You receive draws from a credit line as the build progresses. Interest-only payments during this phase.
• Phase 2 — Permanent: Once the build is complete and inspected, the loan automatically converts to a standard amortizing mortgage (fixed or ARM).

Compare that to the traditional two-loan approach:

• Loan 1: A short-term construction loan (6 to 18 months)
• Loan 2: A takeout mortgage after completion, requiring a full second closing

The two-loan approach costs more (two sets of closing costs), takes more time, and creates refinancing risk if rates move against you between closing 1 and closing 2. The OTC loan eliminates all of that.

How Draw Schedules Work

This is where most spec builders get surprised. The lender does not hand you the full loan amount on day one. Funds are released in stages tied to construction milestones — called a draw schedule.

A typical draw schedule for a spec home looks like this:

• Draw 1 (Foundation): 10 to 15% of the construction budget, released after foundation pour and inspection
• Draw 2 (Framing): 15 to 20%, released after framing, roofing, and rough mechanicals
• Draw 3 (Rough-In): 15 to 20%, after electrical, plumbing, HVAC rough-in passes inspection
• Draw 4 (Drywall / Exterior): 15 to 20%, after drywall, siding, and windows
• Draw 5 (Completion): Remaining balance, released after certificate of occupancy (CO)

Each draw requires an inspector or appraiser to verify the work is complete before funds release. Plan for 5 to 10 business days per draw. Build this into your contractor timeline or you will have cash flow gaps between draws.

Pro tip: Many private lenders allow interest reserves — a portion of the loan held in escrow to pay your monthly interest during construction. This means you do not have to make out-of-pocket interest payments while the build is underway.

What Lenders Actually Look For in 2026

Traditional banks are tightening construction lending. Community banks that used to fund spec builds are now requiring pre-sale contracts or owner-occupied status. Private lenders and portfolio lenders have stepped into the gap — but they look at your deal differently than a bank would.

Here is what actually moves the needle:

1. After-Repair Value (ARV)

Private construction lenders underwrite to the ARV — the projected value of the finished home — not the current dirt value. A strong ARV relative to the loan amount (typically 65 to 75% LTV on the completed value) is the single most important metric. If your deal pencils at 60% ARV-LTV, you will get funded. Your FICO score is secondary.

2. Contractor Track Record

Lenders want to see that your GC has completed similar projects, has active licenses, and carries the appropriate insurance. First-time builders using unlicensed contractors are a red flag. If you are an experienced builder, your project completion history is a major asset — bring it documented.

3. Project Budget and Contingency

Submit a detailed line-item budget. Lenders want to see that you have accounted for contingency (typically 10 to 15% of hard costs) and that the budget is realistic for the market. Builders who submit round-number budgets without backup get slower approvals or more stringent draw conditions.

4. Lot Equity or Down Payment

If you own the lot free and clear, that equity often counts toward your down payment. Many private lenders will advance against lot equity as part of the construction loan structure. If you are buying the lot at closing, expect to put 20 to 30% down on the combined land + construction cost.

5. Exit Strategy Clarity

Spec build or personal use? Lenders want a clear exit. If you are building to sell, provide comparable sales data supporting the ARV. If you are building to rent, provide a DSCR analysis showing the permanent payment is covered by projected rent. Ambiguity here slows deals down.

Construction-to-Perm vs Stand-Alone Construction Loan: Which Is Right for You?

The OTC loan is not always the right move. Here is how to think through it:

If your strategy is build-to-rent — buying lots, building homes, and holding for cash flow — the construction-to-perm loan is almost always superior. You lock in your permanent rate at the time of the initial close, so if rates rise during construction, you are protected.

Markets Where Private Construction Lenders Are Most Active in 2026

Lender appetite is not uniform across the country. In 2026, the most active private construction lending markets are:

• Florida: Tampa Bay, Orlando, Jacksonville, and South Florida corridors. Strong demand for both spec SFR and townhomes. Lenders active on 60 to 75% ARV-LTV.
• Texas: DFW, Houston, Austin, and San Antonio suburbs. High volume, competitive lender market. Some lenders waiving personal guarantee requirements for experienced builders.
• Georgia: Metro Atlanta, Savannah, and suburban growth corridors. Land prices still reasonable relative to ARV, making deals pencil well for lenders.
• South Carolina: Charleston, Myrtle Beach, Greenville. Coastal and inland spec build activity increasing. Fewer competing lenders means faster decisions from private capital.

If you are building in any of these markets, you are in a geography where private capital wants to deploy. The key is packaging your deal correctly.

Common Mistakes That Kill Construction Loan Applications

1. Submitting an incomplete appraisal package. Lenders order a prospective appraisal based on your plans and specs. Missing blueprints, incomplete spec sheets, or no comparable sales data delays this by weeks.
2. Underestimating the timeline. If you budget for a 6-month build and it takes 10, your interest reserve runs out and you have to cover payments out of pocket. Build in buffer.
3. Using the wrong contractor. A GC without a track record or proper licensing is a hard decline at most lenders. Vet your contractor before you apply.
4. Applying to the wrong lender. Banks are pulling back from spec construction in 2026. Applying to 3 banks and getting 3 declines wastes 90 days. Go directly to private lenders who are active in the product.

What to Expect in Terms of Rates and Fees

Private construction loan pricing in 2026 varies by deal, lender, and market. Typical ranges for experienced builders:

• Interest rate during construction: 9% to 13% annualized (interest-only on drawn balance)
• Origination fee: 1 to 3 points
• Loan term: 12 to 18 months for the construction phase
• LTV / LTC: 65 to 75% of ARV, or up to 85% of total costs for strong deals

For the permanent phase (OTC loans), the converted rate is typically set at market rates at time of conversion, or locked at close depending on the lender’s product structure. Always confirm whether your rate converts at market or is locked at the initial close — this distinction is critical if you expect a multi-year build.

Every deal is different. Rates, terms, and eligibility depend on the specific project, lender, and your experience profile. Funding is always subject to lender approval.
