Custom home construction in LA typically requires a construction loan with 20 to 25 percent down. Construction-to-permanent loans convert to a mortgage after completion, saving one set of closing costs.
Short-term loan (12-18 months) that funds construction in draws as work progresses. Interest-only payments on drawn amount. Rates: prime + 1-3% (currently 8-11%). Requires: 20-25% down, approved plans, builder contract, and appraisal of the completed home. Lender inspects at each draw.
One loan, one closing. Starts as construction loan, automatically converts to 30-year fixed mortgage at completion. Saves $5K-$10K in duplicate closing costs. Best option for most LA custom home builds. Requires: same qualifications as construction loan plus permanent mortgage approval.
If buying land separately: land loan (30-50% down, shorter term, higher rate) then construction loan. Some lenders combine land + construction into a single construction loan if you close simultaneously. Strategy: negotiate land purchase contingent on construction loan approval.
Land: $300K (Valley) to $5M+ (Brentwood, Palisades). Construction: $400-$1,500/sqft. Soft costs (design, permits, engineering): 10-15% of construction. Total for a 3,000 sqft custom home in the Valley: $1.5M-$2.5M. Westside: $3M-$7M+. Lenders want to see a complete budget before approving.

“Construction financing for custom homes in LA is more complex than for standard residential purchases, and the lender landscape is dominated by local and regional banks rather than the national lenders most homebuyers are familiar with. The key difference is that construction loans fund in draws as work progresses — not all at once — which means the lender needs confidence in the builder, the plans, and the schedule. Lenders will ask to see a licensed GC contract, a budget breakdown by phase, and plans that have at minimum passed plan check. Many require permits in hand before issuing the first draw.”
Always get the construction loan commitment letter in writing before finalizing your GC contract, not after. I have seen clients negotiate a contract with a GC, sign it, and then discover they do not qualify for the construction loan they planned on — then try to back out of the GC contract with legal complications. Financing commitment should precede GC contract execution in the same way it precedes a real estate purchase contract.
1. Choosing a construction loan based on the lowest advertised interest rate without reading the draw schedule, inspection requirements, and contingency fund requirements — some loans restrict the contingency release in ways that create cash flow problems mid-project
2. Not locking in a construction-to-permanent loan (one-time close) before interest rates move, then facing dramatically higher permanent financing costs when the project completes
3. Underestimating the owner's equity contribution required — most LA construction lenders require 20 to 30 percent equity in the total project cost (land plus construction), and the land value must be confirmed by an MAI appraisal, not a Zillow estimate
A construction lender who does not require independent draw inspections before releasing construction funds is a red flag — not for you, but it tells you something about their lending standards. Legitimate construction lenders inspect the work before each draw. If a private lender offers to fund a construction project based on your attestation alone without independent inspection, their pricing and terms are almost certainly unfavorable in other ways.
A construction loan funds in draws as milestones are completed (foundation, framing, rough-in, drywall, finishes, completion). The lender sends an inspector before each draw to verify the work is complete. You pay interest only on funds drawn during construction. At completion, the loan converts to a permanent mortgage (one-time close) or you refinance to permanent financing (two-time close). LA lenders typically limit draws to 4 to 6 per project.
LA construction lenders typically require 20 to 30 percent of the total project cost (land plus construction) as an equity contribution. If you own the land free and clear, its appraised value counts toward the equity requirement. On a $3,000,000 project (land plus construction), that means $600,000 to $900,000 in equity — typically from land value plus cash contribution.
Construction loan rates in LA run 1 to 3 percentage points above the 30-year fixed rate. As of early 2026, expect construction loan rates in the 7.5 to 9.5 percent range on a variable-rate product. One-time close construction-to-permanent loans lock the permanent rate at origination, which protects against rate increases but may mean a higher initial rate vs. waiting until construction completion.
Yes. If you own an existing home with substantial equity in an LA neighborhood, many lenders will accept it as cross-collateral for a construction loan on a new property. This is common for clients who are building a replacement home while still living in their current home. The existing home's equity reduces the cash contribution required for the new construction project.
