Definition
A construction loan is a short-term financing option that provides funds to build a new home or complete major renovations on an existing property. Unlike traditional mortgages that provide a lump sum upfront, construction loans disburse money in stages as the project progresses, with the lender inspecting the work before releasing each payment.
These loans typically last 6-18 months and carry higher interest rates than conventional mortgages because they're considered riskier for lenders. During construction, borrowers usually pay only interest on the amount drawn, not the full loan amount. Once construction is complete, the loan either converts to a permanent mortgage (called a construction-to-permanent loan) or must be paid off, often by securing a traditional mortgage.
Construction loans require detailed plans, budgets, and contractor information before approval. Lenders want to ensure the project will be completed on time and within budget, as an unfinished property provides poor collateral. The loan-to-cost ratio typically ranges from 70-80%, meaning borrowers need substantial cash for down payments and cost overruns.
How It Applies to HELOCs
Homeowners sometimes use a HELOC as an alternative to construction loans for major renovations or additions. While construction loans require extensive documentation and staged funding, a HELOC provides flexible access to your home's equity with simpler approval processes. During your HELOC's draw period, you can withdraw funds as needed for materials and contractor payments, paying interest only on what you use.
However, HELOCs typically offer lower borrowing limits than construction loans and may not cover the full cost of major projects like room additions or complete renovations. Many homeowners combine both: using a HELOC for initial costs and design work, then securing a construction loan for the major building phase. This strategy can help bridge timing gaps and provide more financing flexibility than either option alone.
How It Applies to DSCR Loans
Real estate investors often use construction loans to build rental properties from the ground up or complete major renovations that will increase rental income. Since construction loans focus on the project's completion rather than current rental income, they can be easier to qualify for than DSCR loans during the building phase. However, investors must plan their exit strategy carefully.
Once construction is complete, many investors refinance into DSCR loans to hold the property long-term. The newly built or renovated property should generate sufficient rental income to meet DSCR requirements (typically 1.0-1.25x debt coverage). This strategy allows investors to build equity through construction, then transition to stable long-term financing based on the property's income potential. Some investors also use existing rental property equity through cash-out refinances to fund construction loan down payments.
Example Calculation
Construction Loan Example: An investor wants to build a $300,000 rental duplex.
Loan Terms:
- Construction loan amount: $240,000 (80% loan-to-cost)
- Required down payment: $60,000 (20%)
- Interest rate: 8.5% (interest-only during construction)
- Construction period: 12 months
Monthly Interest Payments:
- Month 1: $50,000 drawn × 8.5% ÷ 12 = $354
- Month 6: $150,000 drawn × 8.5% ÷ 12 = $1,063
- Month 12: $240,000 drawn × 8.5% ÷ 12 = $1,700
Total Interest Paid: Approximately $12,750 during construction
Exit Strategy: After completion, refinance to DSCR loan at 7.5% rate with $2,800 monthly rental income covering the $2,100 mortgage payment (1.33x DSCR).
