Understanding Construction Financing

Construction Loans vs. Mortgages

Construction loans are short-term financing with funds released in stages as work progresses. They typically have higher interest rates than traditional mortgages and require detailed project plans and budgets. Many borrowers convert to a permanent mortgage after construction completes.

Draw Schedule & Inspections

Lenders release funds in "draws" tied to construction milestones. Each draw requires an inspection to verify work completion before releasing funds. Typical draws occur after foundation, framing, rough-in, and final completion stages.

Interest Rate Factors

Your interest rate depends on credit score, down payment, loan-to-value ratio, and market conditions. Rates for construction loans are typically 0.5-2% higher than traditional mortgages due to increased risk. Shopping multiple lenders can save thousands over the loan term.

Contingency Planning

Always budget 10-20% contingency for unexpected costs like site conditions, material price increases, or design changes. Construction projects rarely come in exactly on budget. Having reserves prevents project delays and the need for emergency financing at unfavorable terms.

Construction Loans 101

Financing a construction project is very different from buying an existing house. You don't get all the money at once. Instead, you get a "Construction Loan" that pays out in stages as the work is completed.

The Draw Schedule

The bank releases funds in "draws" based on milestones.

Draw 1: Foundation complete.
Draw 2: Framing & Roof complete.
Draw 3: Mechanicals (Plumbing/Electric) rough-in.
Draw 4: Drywall & Finishes.
Draw 5: Final completion & Certificate of Occupancy.

Types of Financing

Construction-to-Permanent

The "All-in-One" loan.

One Closing: You pay closing costs only once.
Conversion: Once the house is built, the loan automatically converts to a standard mortgage.

Construction-Only Loan

Short-term financing (usually 1 year).

Two Closings: You pay off this loan when the house is done and get a separate mortgage.
Flexibility: Good if you have a lot of cash or plan to sell the house immediately.
