Loan Officer's Guide to Ground-Up Construction Loans

Your investor client has done well flipping houses — you’ve financed a couple of his exits — and now he’s leveling up: he found a vacant lot in a hot part of town, has a builder lined up, and wants to put up a brand-new home he can sell for $650,000. He needs the money to buy the land and fund the build. And once again, you’re stuck, because there’s no house to lend against — just dirt, a set of plans, and a completed value that exists only on paper.

So he finds a construction lender, and that lender becomes his financing partner for this build and the next three. Ground-up construction loans are how you stay in the deal as your best investor clients graduate from flipping to building. This guide explains how construction financing is underwritten, the moving parts that make it different, and how — through a referral or broker relationship — you get paid on projects you were never set up to originate. It links to current terms on our ground-up construction page.

What a ground-up construction loan is

A construction loan is short-term, asset-based financing that funds the creation of a building from vacant land or a teardown through to a finished, sellable or rentable property. It’s a close relative of the fix-and-flip loan, but with more moving parts:

• It funds land + build. The loan covers acquiring the lot and the full construction budget.
• It releases in draws. The build budget isn’t handed over at closing — it funds in stages as construction milestones are completed and inspected.
• It’s underwritten on completed value. Approval rests on what the finished property will be worth, not on the empty lot.
• It’s interest-only and short. Terms typically run 12–24 months to allow for the build, interest-only, with a balloon at the exit.
• Plans, permits, and a builder matter. The lender underwrites the project and the team executing it.

The mental model: a construction loan is a bet on a building that doesn’t exist yet, structured so the lender only releases cash as that building actually rises out of the ground.

The numbers and factors that drive approval

You don’t underwrite these, but knowing the inputs lets you pre-screen a project in one conversation.

1. Land cost. The lot’s price or current value — the foundation of the total basis.

2. Build budget. The full, line-item cost to construct: materials, labor, permits, soft costs, and a contingency for overruns. A credible budget is the document the whole file rests on.

3. Loan-to-Cost (LTC). The share of total project cost (land + build) the lender funds — strong, experienced builders reach the high end; first-timers get less.

4. Completed value (ARV / as-completed). The appraised value of the finished property, which caps the loan the same way ARV caps a flip.

5. Builder experience. The track record of the borrower and their general contractor directly sets leverage and pricing.

As with a flip, the lower of the LTC cap and the completed-value cap wins. Send us the scenario — land cost, build budget, plans, completed value, and builder experience — and we’ll tell you same-day whether it pencils.

Draw schedules: the heartbeat of a construction deal

This is the mechanic that trips up newcomers, so understanding it makes you credible. Construction money doesn’t arrive all at once:

• The loan funds the land at closing.
• The build budget is held and released in stages — foundation, framing, roof, mechanicals, finishes — each after an inspection confirms the work is done.
• The borrower or GC floats each phase and is reimbursed at the next draw.

For your borrower, the practical message: you need working capital and a GC who can carry costs between draws. A builder who can’t float a phase stalls the whole project — and every week of delay is another week of interest-only carry eating the margin. Coaching a borrower on draw-cash management is real value you add before the file ever moves.

The deals that are really construction files

You’ll recognize these the moment a borrower describes them — and none is a residential or generalist loan:

The borrower…	Construction answer
Bought a vacant lot to build a home to sell	Spec build — exit is a sale
Wants to build new rentals to keep	Build-to-rent — exit is a DSCR refinance
Is tearing down and rebuilding	Ground-up on a teardown basis
Is a flipper leveling up to new construction	The classic flip-to-build graduation
Wants to build a small multifamily or several units	Construction, sized on completed value

If there’s land and a build budget instead of an existing house, it’s a construction referral. Forcing it onto a purchase or rehab product just wastes everyone’s time.

Spec vs. build-to-rent: the exit shapes the deal

Two exits, two different underwrites:

• Spec build — constructed to sell on completion. The exit is a sale, and the deal is judged on the spread between completed value and total cost.
• Build-to-rent — constructed to hold and rent. The exit is a refinance into a DSCR loan once leased, and the deal is judged partly on the finished property’s rent coverage.

Knowing which exit the borrower intends tells you — and the lender — how the takeout works and what to stress-test. A borrower who says “I’ll sell it or rent it, haven’t decided” needs both exits to pencil, which is a stronger, more flexible file.

Rates, terms, and timelines to set expectations

You won’t quote these, but framing them makes you the advisor who prepared the borrower:

• Rate: asset-based pricing similar to other short-term investor debt, set by experience, leverage, and project risk.
• Term: 12–24 months, interest-only, balloon at completion/exit — longer than a flip to allow for the build.
• Leverage: high LTC for experienced builders; lower for first-timers, capped by completed value.
• Draws: funded per inspected milestone.
• Close: faster than the build itself — but the project timeline is the real clock.

The framing that keeps a borrower grounded: on a build, the enemies are budget overruns and timeline slippage. A realistic budget with a real contingency and a disciplined GC matter more to the borrower’s profit than shaving the rate. Time and cost discipline win construction deals.

A worked example you can walk a borrower through

Your client’s spec build: $150,000 lot, $350,000 build budget, $650,000 completed value.

• Total project cost: $500,000
• Completed-value cap at 70%: $455,000
• LTC cap at 85%: $425,000
• Loan (lower of the two): $425,000
• Borrower cash in: ~$75,000 + closing costs + carry reserve + contingency
• Term: ~12–18 months interest-only to build and sell
• Exit: sell at $650,000 — or, if build-to-rent, refinance into a DSCR loan once leased

The project lives or dies on the spread between the $650,000 completed value and the all-in cost (land + build + carry + costs), not on the note rate. Frame that, and you’ve turned “there’s no house to lend on” into a fundable plan.

How the construction file moves, step by step

Stage	What happens
1	Borrower submits land cost, plans, permits, line-item build budget, completed value, and builder/GC experience
2	Lender sets LTC and completed-value caps, evaluates the budget and team, issues a term sheet
3	As-completed appraisal ordered; title and entity docs collected
4	Loan closes; land funds; draw schedule set
5	Builder completes a milestone, requests inspection
6	Draw releases after approval; repeat through the build
7	Exit: sale or DSCR refinance pays off the note

The stalls are an unrealistic budget, permit delays, or a GC who can’t float between draws. Coach all three at intake and the project runs on schedule.

What your borrower will ask you — and how to answer

“There’s no house yet — how can I get a loan?” The loan is underwritten on the completed value and funds in stages as you build. The lender releases cash as the property actually rises.

“I’ve never built before — am I out?” No, but you’ll bring more cash, use a licensed GC, and keep the budget conservative. A credible team de-risks a first-timer.

“When do I get the construction money?” In draws, after inspection at each milestone — not upfront. Plan working capital to float your GC between draws.

“What if I go over budget?” That’s what the contingency is for, and why lenders scrutinize the budget. Overruns burn margin and add carry, so build in a real cushion.

“Should I sell it or rent it when it’s done?” Either — sell for a spec profit, or refinance into a DSCR loan and hold it. Deciding early sharpens the underwrite; keeping both open makes a flexible file.

A second example: build-to-rent, small multifamily

Your client wants to build a small 4-unit rental building: $200,000 land, $600,000 build, $1,050,000 completed value, projected rents of $8,800/month total.

• Loan: sized on the lower of LTC and completed value — roughly $680,000–$720,000
• Exit: refinance into a DSCR loan once leased, tested on the ~$8,800 rent vs. the permanent payment
• Why it works: the finished, rented building supports permanent debt that retires the construction loan
• What you did: recognized a flip-to-build-to-hold investor and routed a deal that chains construction into a DSCR takeout

The lesson: construction isn’t only single-home spec builds. Build-to-rent chains a construction loan into a DSCR refinance — one investor, two loans, both routable through you.

Construction vs. fix-and-flip vs. DSCR: a cheat sheet

	Ground-up construction	Fix-and-flip	DSCR
Starting point	Vacant land / teardown	Existing distressed house	Stabilized rental
Funds	Land + full build	Purchase + rehab	Permanent hold
Underwritten on	Completed value / LTC	ARV / LTC	Rent vs. PITIA
Term	12–24 mo, IO	6–18 mo, IO	30 yr
Exit	Sale or DSCR refi	Resale or DSCR refi	Long-term hold

The pattern: construction builds it, DSCR holds it (or a sale exits it). It’s frequently the first loan in a chain that ends in a DSCR refinance — one relationship, two loans, both potentially yours.

Your move: refer it or broker it

You don’t underwrite construction deals, manage draws, or carry the risk. You do one of two things:

Refer it. Send the borrower and the project; Jaken Finance Group originates, funds, and manages draws; you’re paid a referral fee. The right default for most residential LOs.

Broker it. Stay on the file and broker it through Jaken Finance Group for broker compensation.

The compliance note specific to you: your consumer-mortgage referral-fee limits come from RESPA, which governs consumer-purpose residential transactions. A ground-up construction loan on investment property is a business-purpose loan — a different category, which changes the analysis. An owner-occupied construction loan is treated differently again, so confirm any specific scenario with compliance or counsel, and flag owner-occupied cases and we’ll advise on the compliant path.

For the common investor construction deal, the clean start is our referral-partner program: flag the project, we handle origination, draws, and disclosures, and you keep the client for the sale or DSCR takeout. Prefer to stay hands-on? Become a Jaken Finance Group broker.

The bottom line

Ground-up construction isn’t a product you’ll underwrite from a residential desk — it’s the next chapter of your best investor clients’ careers, and one you learn to recognize. The vacant lot, the build budget, the flipper leveling up to new construction: every one is a construction referral hiding behind the fact that there’s no house to appraise yet. You don’t need to know draw mechanics or build budgeting cold. You need to know it’s fundable, understand draws and completed-value well enough to set expectations, and have a partner who builds these deals.

Your client is going to put up that house this year — with or without you financing it. The only question is whether you’re still his lender when he builds the next subdivision. Send us the scenario and we’ll tell you today whether it works.
