How Do I Finance Building a Home from the Ground Up in the Central Coast?
In the Central Coast, Monterey, San Luis Obispo, Santa Barbara, building a home is financed with a construction loan that releases funds in stages (draws) as the build progresses, with interest charged only on what's drawn. The key choice is a single-close construction-to-permanent loan, one closing that converts to a regular mortgage at completion, versus a stand-alone construction loan you refinance afterward. Expect 20 to 25% down on total project cost (land plus construction), a 680+ credit score, detailed plans, and a lender-approved builder; rates run about 7 to 9% during the build. High build costs, coastal review, and premium lots define custom building here, so budget and timeline discipline are essential. Ashlar Lending structures the loan and manages the draws; Serve First underwrites the lot; Ashlar LDA prepares the entity.

How a Central Coast construction loan actually works
A construction loan funds a build in stages, not all at once. Here's how the pieces fit, with Ashlar Lending on the financing, Serve First on the lot and feasibility, and Ashlar LDA on the entity:
Choose construction-to-permanent or stand-alone
The biggest decision is structure. A single-close construction-to-permanent (CTP) loan closes once, funds the build, and then converts automatically into a regular mortgage when the home is finished, one set of closing costs, and you can often lock the permanent rate up front. A stand-alone construction loan funds only the build and must be refinanced into a permanent mortgage at completion, meaning a second closing and re-qualifying at whatever rates exist then. CTP is usually the cleaner, cheaper path; Ashlar Lending helps you choose.
Understand the draw schedule and interest-only payments
Unlike a mortgage, a construction loan doesn't hand you the full amount. The lender releases funds in a series of draws, typically four to six, triggered by milestones: foundation, framing and roof, mechanical/electrical/plumbing rough-in, drywall, and completion. Each draw is usually verified by an inspection. During the build you pay interest only on the amount drawn so far, which keeps early payments low. A draw schedule matched to how your builder actually works keeps subcontractors paid and the project moving. Ashlar Lending manages this with you and the builder.
Meet the requirements, they're stricter than a mortgage
Because you're borrowing against a home that doesn't exist yet, lenders ask for more: typically a 680+ credit score (700+ preferred for the best terms), 20 to 25% down on total project cost (land plus construction), a detailed set of plans and a line-item budget, and a lender-approved, licensed builder with a track record. The underwriter reviews your finances, the builder's qualifications, the budget's reasonableness, and whether the schedule is realistic. Ashlar Lending helps you assemble a package that gets approved.
Plan for Central Coast build costs and permitting
Coastal and high-cost submarkets here carry elevated build costs, longer permitting, and sometimes additional coastal or environmental review, so budget and timeline discipline are essential. Serve First helps confirm the finished-home value supports the project and that your budget reflects local costs and review timelines before you break ground.
Know how the appraisal works, on future value
A construction loan is underwritten against the appraised value of the completed home, based on your plans and specifications, not the empty lot. That's what lets the loan fund a house that isn't built yet. But it also means a build that appraises below cost can leave a funding gap you'd have to cover, so a realistic budget and comparable finished-home values matter. Serve First checks that the finished-home value supports the project before you commit.
Budget a real contingency, construction runs over. The most common way a build gets into trouble is money: projects routinely run over budget and behind schedule, and a construction loan is sized to your original budget. Plan for an extra 15 to 20% contingency beyond your estimates, confirm who covers overruns, and make sure the draw schedule matches your builder's actual cash needs so subcontractors don't walk. Also confirm your loan converts automatically to permanent financing, if it doesn't, you re-qualify at completion at whatever rates exist then. Serve First and Ashlar Lending pressure-test the budget and structure before you break ground.
One family. Land, financing, and entity.
Build from the ground up, with the construction financing lined up first
Building a home is really a financing project with a house at the end of it, so the loan structure and the lot have to be right before the first shovel. The Ashlar Brands family works the whole build:
- Ashlar Lending Inc. (NMLS #2699657) structures the construction financing: single-close construction-to-permanent loans, stand-alone construction loans, and owner-builder options where you qualify, and manages the draw schedule that funds the build in stages.
- Serve First Realty helps you find and underwrite the lot, checks that the site and budget support the finished-home value, and represents you whether you’re building to live in or to sell.
- Ashlar LDA, Inc., a bonded and registered Legal Document Assistant, can prepare the LLC or entity paperwork and deeds at your direction.
These are separate businesses in the Ashlar Brands family. Serve First is a real estate brokerage, not a lender or law firm; loan terms, rates, draw schedules, and owner-builder eligibility are set by the lender. A Legal Document Assistant prepares documents at your direction and is not a substitute for an attorney. This is general information, not tax advice.
Building in the Central Coast: the steps
Line up the lot and the loan together
Tell Serve First and Ashlar Lending your plans, budget, and whether you already own the lot, land equity can serve as part of your down payment. If you're still buying, start with our land guide.
Get pre-approved and choose your structure
Ashlar Lending pre-qualifies you, helps you choose construction-to-permanent or stand-alone, and reviews your builder and budget for Central Coast.
Close and build on a draw schedule
Close the loan, then the lender funds the build in draws at each milestone while you pay interest only on what's drawn; Ashlar LDA prepares any entity and deeds at your direction.
Convert to a permanent mortgage
At completion and certificate of occupancy, a construction-to-permanent loan converts to your regular mortgage, or, with a stand-alone loan, you refinance into permanent financing.

What's the difference between construction-to-permanent and stand-alone construction loans?
A construction-to-permanent (CTP) loan is a single-close loan: you close once, it funds the build, and it converts automatically into a regular mortgage when the home is finished, one set of closing costs, and you can often lock the permanent rate up front. A stand-alone construction loan funds only the build and must be refinanced into a permanent mortgage at completion, meaning a second closing and re-qualifying at whatever rates exist then. CTP is usually cheaper and less risky. Ashlar Lending helps you choose.
How much do I need to put down to build a home?
Typically 20 to 25% of the total project cost (land plus construction), though a few lenders offer around 10% for well-qualified borrowers. If you already own the lot, your land equity can count toward the down payment, sometimes covering much of it. Lenders also want a 680+ credit score (700+ for the best terms), detailed plans and budget, and an approved builder. Ashlar Lending can tell you what your specific project would require.
How does a construction loan pay for the build?
Through a draw schedule. Rather than giving you the full amount at once, the lender releases funds in stages, usually four to six draws, as the project hits milestones like foundation, framing, rough-in, and completion, with each draw typically verified by an inspection. You pay interest only on the amount drawn so far during construction, so early payments are low and rise as more is drawn. Ashlar Lending coordinates the draws with you and your builder.
Can I be my own contractor with an owner-builder loan?
Sometimes, but it's harder. Owner-builder loans let a qualified borrower act as their own general contractor, which can save on builder margin, but fewer than one in five lenders offer them, they require more documentation and proof you can manage the build, and they often carry higher rates and stricter terms. Most people build with a licensed general contractor, which lenders strongly prefer. Ashlar Lending can tell you whether an owner-builder loan is realistic for you.
What are construction loan rates in 2026?
Construction loan rates typically run about 1 to 2 percentage points above conventional mortgage rates because the lender is financing a home that doesn't exist yet, roughly 7 to 9% during the construction phase, often as a variable rate. With a construction-to-permanent loan, the rate converts to a fixed permanent mortgage (often around 6.5 to 7.5%) when the build finishes. Private and owner-builder loans can run higher. Your rate depends on credit, down payment, and the project; Ashlar Lending shops it for you.
