Construction Loans 101:
How Building Your Dream Home Gets Financed
Ariane Bibas · Mortgage Loan Officer · NMLS #2833531 · CA DRE #02225025
Most mortgages answer a simple question: what is this home worth today? Construction and renovation loans answer a more interesting one: what will it be worth when the vision is built? That difference is what can let you buy a tired property and transform it — or build from the ground up — without funding the work in cash.
The Mechanics: One Loan, Released in Stages
A construction loan doesn't hand you the full amount at closing. The purchase (or the payoff of your existing mortgage) funds first, and your construction budget goes into an escrow account. As your contractor completes each phase — foundation, framing, mechanicals, finishes — an inspector verifies the work and the lender releases a "draw" to pay for it.
With a one-close (construction-to-permanent) structure, you have one loan throughout, and when the work is done it converts to a standard long-term mortgage — one closing, one set of closing costs. Construction-only loans work differently and require a second loan afterward.
After-Renovation Value: The Number Everything Hangs On
Lenders size these loans against the appraiser's opinion of the home's value after the work — the ARV. Many renovation programs cap the loan at a percentage of the lesser of (purchase price + renovation budget) or the appraised ARV, and that cap varies by program. As an illustration only: buying at $750,000 with a $200,000 renovation and a finished value appraised at $1,050,000, a program cap would apply to the lesser figure, $950,000 — and you'd still need to qualify. If the appraisal doesn't support the finished value, the loan shrinks — which is why the quality of your plans and budget matters so much.
Picking a Program
FHA 203(k), conventional renovation (HomeStyle®), and construction-to-permanent each fit a different project and down payment situation. I've broken down how each one works, step by step, in the Construction & Renovation Loans guide — worth a read before we talk programs.
Where These Projects Actually Go Wrong
In twenty years of running renovations, I've seen the same failure over and over — and it isn't the loan. It's a budget that was never realistic. A bid that's 15% light doesn't feel like a problem at closing; it becomes one at month four, when the contingency is gone and the draws don't cover the work remaining.
This is where my background helps as your loan officer: before we submit anything, I'll read the contractor's bid the way a project manager does — line by line, against real costs — so the loan request is built around a budget that's realistic.
What You'll Need to Apply
- Standard income, asset, and credit documentation — same as any mortgage
- A licensed, insured contractor (I can share what to look for when vetting one)
- A written scope of work and itemized bid
- Plans, if the work is structural
