If you're exploring the idea of building a new property rather than buying an existing one, you need to understand construction loans. They work differently from traditional mortgages and differently from fix-and-flip loans. The draw-based structure, interest-only payments during construction, and focus on project feasibility (rather than your personal income) change the entire financial picture. Let's break down what you need to know before talking to a lender.

What Is a Construction Loan?

A construction loan is short-term financing that funds a building project in phases. Unlike a traditional mortgage that's disbursed in full at closing, a construction loan disburses funds in draws tied to construction milestones. You request a draw, the lender's inspector verifies work is complete, and funds are disbursed. This structure protects both borrower and lender by ensuring funds are being used for actual construction work, not sitting idle or misallocated.

The key distinction from other loans: you only pay interest on money you've actually drawn, not on the full loan commitment. If you have a $1M construction loan commitment but have only drawn $400K, you're paying interest on $400K, not $1M. As you draw more funds (say, to $700K), your interest payment increases proportionally.

How Construction Loans Actually Work

The process starts with pre-qualification. You provide project information: location, scope of work, estimated cost, contractor details, timeline. The lender does a quick feasibility check. If the project makes sense, you get pre-approval and move to formal application.

Formal underwriting requires comprehensive documentation: detailed construction plans, cost breakdown, contractor bids, your financial statements, builder experience details, site photos, and market analysis. This takes 2 to 4 weeks. The lender evaluates whether the finished property value supports the loan amount (LTC and LTARV ratios).

Once approved, you close the loan. At closing, two important things happen: The lender disburses the initial draw (usually 5 to 10 percent of the loan, often enough to acquire the land or begin site prep) and funds an interest reserve account. This interest reserve covers 12 to 18 months of estimated interest. You're not writing monthly checks; interest accrues from this reserve.

As construction progresses, you submit draw requests. Your contractor certifies work is complete for that phase, provides proof subs were paid (lien waivers), and you request funds. The lender sends an inspector to verify work matches contract specs. Once approved, funds are disbursed in 3 to 5 business days. This cycle repeats for each phase until construction is done.

The Critical Numbers: LTC and LTARV

Two ratios determine how much you can borrow: LTC and LTARV.

LTC is Loan-to-Cost, the loan amount divided by total project cost. Total cost includes land, hard costs (labor and materials), soft costs (permits, architect, insurance), and contingency. If your project costs $500K and you borrow $400K, your LTC is 80%. Most lenders offer up to 85% LTC for qualified projects.

LTARV is Loan-to-After-Repair-Value, the loan amount divided by the finished property's projected value. If your finished property will appraise at $600K and you borrow $450K, your LTARV is 75%. Most lenders cap LTARV at 75%.

Most deals hit one constraint first. A project with high soft costs but strong finished values typically maxes out on LTC. A project with lower finished values relative to construction cost maxes out on LTARV. Both limits protect the lender (and you, if the market shifts). Understanding these ratios before you apply prevents surprises during underwriting.

How New Construction Differs from Fix-and-Flip

New construction and fix-and-flip are both building projects, but they operate very differently.

Fix-and-flip finances the purchase of an existing property plus renovation costs. The property exists, so there's an appraisal, comparable sales data, and known condition. Underwriting is faster (10 to 21 days) because the main variables are straightforward. Fix-and-flip loans typically have 12-month terms and fund the full commitment amount or large portions upfront.

Construction loans finance a property that doesn't exist yet. No appraisal comps. No existing condition. Just plans, projections, and the contractor's track record. Construction loans require more detailed feasibility analysis, which takes longer (30 to 45 days) but results in more flexible financing. Construction loans also have longer terms (18 to 24 months) because building takes longer than renovating.

Interest structures differ too. Fix-and-flip loans charge interest on the full funded amount whether funds are drawn or not. Construction loans charge interest only on the outstanding balance drawn. Early in a construction project, this saves significant money. If you average $300K outstanding for 15 months at 9.5%, that's roughly $3,550 per month in interest. But the interest reserve covers this. With fix-and-flip, you'd be paying interest on the full amount from day one.

The Draw Process and What to Expect

Draw timing varies by project phase and construction speed. A typical single-family construction has these phases: site prep and foundation (5%), framing (15%), mechanical/electrical/plumbing rough-in (15%), drywall (15%), interior finishes (25%), final inspection and close-out (25%). These percentages correspond to draw amounts and are aligned with when your contractor's invoices arrive.

When a phase is complete, you submit a draw request with: the draw request form, contractor certificate of completion, lien waivers from all subs and suppliers who were paid for that phase, photos of the work, and inspection request. The lender's inspector meets you on site and verifies work is actually 100% complete, meets contract specs, and matches the draw percentage approved at closing.

Once the inspector approves, the lender disburses funds within 3 to 5 business days. This pace depends on the lender's processing speed and inspector availability. Some lenders are faster than others. If you're time-sensitive, ask about turnaround times during the application process.

What Lenders Look for in Construction Projects

Lenders underwrite construction projects on three key factors: project feasibility, contractor capability, and borrower strength.

Project feasibility means the finished property value is supported by market comps. Is the projected value realistic? Will the property appraise at that value when finished? The lender gets an appraiser to do a construction appraisal that estimates finished value. Overly optimistic projections kill deals.

Contractor capability matters enormously. The lender wants evidence that your contractor has successfully completed similar projects. Typically 3 or more comparable projects. References matter. The lender might call prior clients and ask about schedule adherence, budget control, and quality. A cheap contractor with no track record is a red flag.

Borrower strength (the entity borrowing, not necessarily you personally) needs to demonstrate adequate reserves, good credit (typically 680 or above), and financial capacity to cover overruns or issues. The lender wants confidence that if something goes wrong mid-project, you can step in.

The Exit Strategy: Refinancing into Permanent Financing

Construction loans are temporary bridges. You build, then refinance. The most common exit for investor-owned properties is a DSCR loan. DSCR loans qualify based on rental income, not personal income, making them ideal for investors who might have complex tax situations.

Here's the timeline: You apply for DSCR financing 90 days before construction completes. Provide your DSCR lender with rental comps, floor plans, and projected rent details. They'll lock a rate and issue a rate lock commitment 30 to 60 days before completion. When construction finishes, you close the DSCR loan. The DSCR loan proceeds pay off your construction loan balance. You now own the property with long-term 30-year financing based on rental income.

This structure is where the real power of construction loans emerges. You build with aggressive leverage (85% LTC), minimize cash spent on interest (interest reserve covers construction phase), then refinance into a long-term loan based on the property's performance. If done right, this is scalable wealth building.

Common Mistakes to Avoid

Don't underestimate soft costs. Permits, architect, insurance, and construction management often run 20 to 25% of hard costs. Most first-time builders underbid this category.

Don't hire the cheapest contractor. You're trusting them with a project you've heavily financed. References and previous work matter more than a low bid.

Don't assume market values won't shift. If your projections are aggressive and the market softens, your LTARV constraint tightens. Conservative projections protect you.

Don't ignore timeline buffers. Permits take longer than expected. Weather delays happen. Expect 10 to 15% timeline buffer beyond your best estimate.

Should You Build?

Construction loans make sense when land is available at good pricing and building costs are below market purchase prices for comparable finished properties. Build when you want control over the final product or when you want to optimize for a specific rental market. Build when existing inventory is tight.

Don't build if good deals on existing properties are plentiful in your market. Sometimes buying stabilized properties is smarter than betting on construction timelines and finished values.

The best real estate investors do both. They buy existing cash-flowing properties and build select properties when the math aligns. A portfolio with both strategies is resilient and scalable.

Next Steps

If you're considering building, start by validating the math. Find land, get actual contractor bids, research finished property values in the area, and understand the local permit process. This homework tells you whether construction makes sense for your investment thesis.
