Ground-Up Construction Loans for Investors: How They Work

By MercFinancial · Published 2026-07-18

A ground-up construction loan funds new builds in staged draws sized to project cost, not appraised value. See how LTC, draws, and exits actually work for investors.

A ground-up construction loan for investors is short-term financing that funds the actual build of a property, from a vacant or entitled lot through a certificate of occupancy, released in stages as work is completed rather than handed over as one lump sum at closing. It typically covers a portion of the land cost plus the full hard and soft cost budget, sized against total project cost rather than the finished property's appraised value. Terms usually run 12 to 24 months, carry interest-only payments during the build, and are repaid either by selling the completed property or refinancing into a longer-term rental loan once it's built and leased.

For investors who've built a track record on rehabs and are ready to build new, the jump to ground-up can feel like a different sport, with more ways for a budget to drift before a single wall goes up. Structurally, though, it isn't far from a fix-and-flip loan: both are cost-based, draw-funded, and short-term. The real difference is scale, timeline, and how closely a lender examines the plan and the people executing it.

This guide covers how these loans are structured, what a lender wants to see from a builder without a long resume, how draws get funded, and the two most common exits once the property is finished.

"My rehabs always closed fast because the comps did the talking. On my first ground-up deal I learned the lender wasn't just underwriting the house. They were underwriting me, my contractor, and the schedule."

What a Ground-Up Construction Loan Covers

A construction loan is built around total project cost, not a single purchase price. Depending on the lender and the deal, funds are typically advanced against several cost categories:

• Land acquisition or payoff. A portion of the lot's purchase price, or a payoff if the land is already owned or carries a separate lien.
• Hard costs. Site work, foundation, framing, mechanical/electrical/plumbing, and finishes, every line item tied directly to physical construction.
• Soft costs. Architectural and engineering fees, permits, survey costs, and in some structures a portion of the builder's overhead.
• Contingency reserve. A cushion, usually 5-10% of hard costs, for the change orders and surprises that show up on almost every build.
• Interest reserve. Funds set aside inside the loan to cover monthly interest payments during construction, covered in more detail below.

What it generally does not cover is the finished value of comparable homes nearby. That number caps how much a lender will lend regardless of cost, but it isn't the basis the loan is sized against, unlike a conventional purchase-money mortgage. That's a mental shift for investors coming from rehab or rental financing, where after-repair value or in-place rent does more of the work. For a full breakdown of how these ratios relate, see LTV, LTC, and ARV: The Math Behind Investor Loans.

Typical Structure: Land, Budget, and Loan-to-Cost

Most ground-up construction loans are underwritten on a loan-to-cost, or LTC, basis: the loan amount as a percentage of total project cost (land plus hard costs plus soft costs plus contingency). Wholesale lenders in our network typically land in the 75-85% LTC range for experienced builders on straightforward single-family or small multifamily projects, with the investor covering the remainder as cash equity, often supplemented by equity already sitting in the land if it was purchased below market.

A second ceiling usually applies alongside LTC: loan-to-value against the projected as-completed appraisal, commonly capped around 65-75%. Whichever number produces the lower loan amount generally governs, a deliberate double-check that protects the lender whether the market softens or the budget balloons mid-build.

What Lenders Want to See From First-Time Builders

Not having a construction resume doesn't disqualify an investor, but it shifts what the lender leans on to get comfortable. Wholesale construction lenders generally look for some combination of the following, and a strong showing in one area can offset a gap in another:

• A licensed, bonded GC with a real track record on comparable projects, even if the investor has never built before. The lender is underwriting the build team as much as the borrower.
• A detailed, line-item budget tied to actual bids or a signed GC contract, not a rounded estimate. Vague budgets are a fast way to get a deal re-traded or declined.
• A realistic timeline that matches the scope. A 6-month schedule on a build that typically takes 10 reads as inexperience.
• Site control and entitlements squared away: permits pulled or on track, utilities available, no zoning surprises pending.
• Reserves beyond the down payment to absorb overruns without stalling the project if a draw is delayed or a change order hits.
• Liquidity and credit that support the request, since a first build shifts more underwriting weight onto the borrower's overall financial picture.

The experience gap is real, but it's bridgeable, and it's exactly the kind of structuring conversation that benefits from working across a wide lender base rather than a single bank's box. Some programs lean harder on a strong GC in place of borrower track record; others want to see one completed build first. See why investors work with us for more on how matching a deal to the right lender changes the outcome in exactly this scenario.

The Draw Process During Construction

Unlike a purchase loan that funds once at closing, a construction loan releases money in stages as work is completed and verified. The general rhythm looks like this:

This cycle repeats through the build, so cash flow discipline matters as much as construction quality. A contractor used to being paid up front on smaller rehab jobs sometimes needs a direct conversation about how draw-based funding schedules labor and materials around each verified milestone.

Interest Reserves and Carrying Costs While You Build

Most construction loans are structured with an interest reserve: a portion of the loan set aside to cover the interest-only payments due each month during the build. Rather than writing a check out of pocket every month while the property generates zero income, the borrower's payment is effectively funded from within the loan until the reserve is drawn down or the build wraps.

That's real relief on cash flow, but it isn't free money. It's still part of the loan amount, still accrues, and still has to be repaid. Treat it as what it is, a bridge for holding costs, and keep separate reserves for the change orders and delays that push almost every build past its original schedule.

Exit Options: Sell the Spec or Refinance Into a Rental Loan

Because construction loans are short-term by design, every deal needs a defined exit before it starts, and investors generally choose between two paths.

Sell the completed spec home. The property is listed and sold once construction wraps and a certificate of occupancy is issued, with sale proceeds paying off the construction loan. This is the straightforward exit for investors building to sell, carrying the same market-timing and pricing discipline as any flip.

Refinance into a long-term rental loan. Investors building to hold, particularly on build-to-rent projects, refinance the completed and often already-leased property into a longer-term loan sized on its own cash flow, most commonly a DSCR loan, once the construction loan matures. Qualifying on rent rather than personal income is covered in DSCR Loan Requirements for Rental Properties, Explained.

Whichever path fits, the exit should be picked before the loan closes, not figured out at month 10 as maturity approaches. The same logic that governs exit planning on any short-term bridge loan applies here; see Bridge Loan Exit Strategies: Picking Yours Before You Borrow. If the market shifts mid-build, having both paths pre-qualified gives room to pivot without scrambling.

Documents to Prepare Before You Apply

Construction underwriting moves faster with a complete file. Have these ready:

• Purchase contract or deed for the land, plus payoff statement if there's an existing lien
• Signed GC agreement or bid, with license and insurance information
• Line-item construction budget covering every cost category, not a rounded total
• Construction timeline or schedule of values matching the draw stages
• Approved plans and specs, along with permit status
• Personal financial statement and two years of tax returns
• Proof of liquidity for the down payment plus reserves
• Entity documents if closing in an LLC, plus a personal guaranty where required
• Builder resume or portfolio if the GC's track record is offsetting the investor's own experience gap

Every wholesale lender weighs this file a little differently, which is where working across a broad set of construction-focused programs pays off instead of taking a single lender's answer as final. Our real estate funding programs cover ground-up construction alongside fix-and-flip, bridge, and DSCR rental financing, so a deal that doesn't fit one box often fits another.

Frequently Asked Questions

Can a first-time investor get a ground-up construction loan?

Yes. Underwriting leans more heavily on other factors to offset the missing track record, most often a licensed general contractor with real build experience, a detailed line-item budget backed by actual bids, and stronger liquidity or credit. Leverage may run somewhat lower on a first build, but no construction history is not an automatic decline.

Do construction loans cover the land purchase?

Often, yes, but usually only a portion of the land cost, and the exact percentage depends on whether the land is being acquired at closing or already owned. Investors holding the lot with meaningful equity, or free and clear, typically see better overall leverage than those asking the loan to fund land and construction from zero.

What is loan-to-cost on a construction loan?

Loan-to-cost, or LTC, is the loan amount expressed as a percentage of total project cost, meaning land plus hard, soft, and contingency costs, rather than a percentage of the property's finished market value. It's the primary metric used to size the loan, alongside a separate loan-to-value cap based on the as-completed appraisal.

Do I need a general contractor to qualify?

Most wholesale construction lenders require a licensed, bonded GC on the project, whether a third party or the investor themselves if they hold a contractor's license and relevant experience. True owner-builder arrangements without any licensed contractor are difficult to finance through most wholesale programs.
