How a Traditional Mortgage Works
A mortgage is a loan to buy a property that already exists. The bank gives you a lump sum at closing. You use it to pay the seller. Then you repay the bank over 15-30 years with monthly payments that include principal and interest.
The property is the collateral. The bank can appraise it, inspect it, and confirm it's worth what you're paying. That's why mortgage rates are lower than most other real estate loans. The risk to the lender is relatively small because the building is already standing.
Here's what a standard mortgage looks like:
- Interest rates: 6-8% (varies by credit, loan type, and market conditions)
- Terms: 15-30 years
- Down payment: 3-20% for residential, 20-25% for investment properties
- Disbursement: One lump sum at closing
- Payments: Principal + interest from month one
- Approval time: 3-6 weeks
- Collateral: The existing property
Mortgages are the simplest real estate loan. You apply, get approved, close, and start making payments. No draw schedules. No inspections during the loan term. No short-term deadlines.
How a Construction Loan Works
A construction loan funds building a new structure from the ground up. The lender doesn't give you all the money at once. Instead, it releases funds in stages called draws as each phase of construction is completed and inspected.
During the build, you make interest-only payments on the amount that's been drawn. Not the full loan amount. So in month one, if only 15% of the loan has been released, you're paying interest on that 15%. Your payment grows over time as more money is drawn.
Construction loans are short-term. Most have terms of 12-24 months. Once the build is done, you either sell the property or refinance into a permanent mortgage. Our construction loan guide walks through the full draw process step by step.
Here's what a standard construction loan looks like:
- Interest rates: 7-12%
- Terms: 12-24 months
- Down payment: 10-20% of total project cost (land + construction)
- Disbursement: Draw-based (released in stages after inspections)
- Payments: Interest-only on drawn funds during construction
- Approval time: 3-6 weeks (more documentation required)
- Collateral: The land and plans (the building doesn't exist yet)
Why are construction loans more expensive? The lender is financing something that doesn't exist yet. There's no building to foreclose on if things go wrong. The project could go over budget, the contractor could walk off the job, or the market could shift before the build is done. Higher rates reflect that added risk.
Construction Loan vs Mortgage: Side-by-Side
Here's how the two compare on the details that matter most.
| Criteria | Traditional Mortgage | Construction Loan |
|---|---|---|
| Purpose | Buy an existing property | Build a new structure |
| Interest Rate | 6-8% | 7-12% |
| Term Length | 15-30 years | 12-24 months |
| Down Payment | 3-20% | 10-20% of total project cost |
| How Money Is Released | Lump sum at closing | In draws (stages) after inspections |
| Monthly Payments | Principal + interest from day one | Interest-only on drawn funds during build |
| Collateral | Existing property | Land + building plans |
| Documentation | Income, credit, appraisal | All of that + plans, budget, contractor, permits |
| Approval Time | 3-6 weeks | 3-6 weeks (more docs required) |
| Credit Score | 620+ (varies by program) | 680+ for most programs |
Key Takeaway
A mortgage is simpler, cheaper, and easier to get. A construction loan is built for a completely different job. You can't use a mortgage to build from scratch, and a construction loan isn't meant for buying an existing home.
- Mortgage = buying something that already exists
- Construction loan = building something new from the ground up
- The right loan depends on what you're doing with the property
Construction-to-Permanent Loans: The Hybrid Option
If you're building a home you plan to keep (either live in or hold as a rental), a construction-to-permanent (C2P) loan combines both steps into one.
How it works
You close one time. During the construction phase, the loan works like a standard construction loan with draws and interest-only payments. When the build is done, it automatically converts into a permanent mortgage. No second application. No second closing. No second set of fees.
One closing vs two closings
Without a C2P loan, you'd need two separate loans: a construction loan to build, then a mortgage to pay off the construction loan. That means two applications, two appraisals, two sets of closing costs (2-5% of the loan each time), and the risk that you don't qualify for the mortgage after construction.
A C2P loan eliminates all of that. You lock in your permanent rate before construction starts. You know exactly what your mortgage payment will be when the build is done.
| Feature | Two Separate Loans | Construction-to-Permanent |
|---|---|---|
| Closings | 2 (construction + mortgage) | 1 |
| Closing costs | Paid twice | Paid once |
| Rate lock | Construction only; shop for mortgage later | Both phases locked from the start |
| Requalification risk | Must qualify again for the mortgage | No requalification needed |
| Best for | Borrowers who want to rate-shop later | Borrowers who want certainty and lower costs |
Pro Tip: For most owner-builders, the C2P loan is the better deal. You save $5,000-$15,000 in closing costs and eliminate the risk of not qualifying for a mortgage after the build. The only reason to use two separate loans is if you think rates will drop enough during construction to offset the extra closing costs.
What Happens During Construction: The 5-Draw Walkthrough
The draw process is what makes a construction loan different from any other type of financing. Here's how it works on a $500,000 construction project.
| Draw | Phase | % of Loan | Amount | Interest Accrual |
|---|---|---|---|---|
| 1 | Foundation | 15% | $75,000 | ~$625/mo (on $75K at 10%) |
| 2 | Framing + roof | 20% | $100,000 | ~$1,458/mo (on $175K total drawn) |
| 3 | Mechanicals (electrical, plumbing, HVAC) | 20% | $100,000 | ~$2,292/mo (on $275K total drawn) |
| 4 | Interior finishes (drywall, flooring, cabinets) | 25% | $125,000 | ~$3,333/mo (on $400K total drawn) |
| 5 | Final completion + certificate of occupancy | 20% | $100,000 | ~$4,167/mo (on $500K fully drawn) |
How each draw works
- Complete the phase. Your contractor finishes the work outlined for that draw stage.
- Request the draw. You submit a draw request to the lender with documentation and photos.
- Inspection. The lender sends a third-party inspector to verify the work matches the approved plans.
- Funds released. Once the inspector signs off, funds are released within 3-7 business days.
Notice how your interest payment grows each month. At the start of the project, you're paying $625/month. By the end, it's $4,167/month. This is a key planning detail. Budget for your monthly payment at the highest draw level, not the lowest.
Draw schedules vary by lender and project. Your lender will set a schedule based on your specific build plan and budget.
Interest reserve option: Some lenders build the expected interest costs into the loan itself. Instead of making monthly payments, the interest accrues and is added to your loan balance. This preserves your cash flow during construction but increases the total amount you owe when the build is done.
When Construction Isn't What You Need
Not every project needs a construction loan. If the property already has a structure on it, there are faster and less complex options.
Renovation project? Use a fix and flip loan.
If you're buying an existing property and renovating it (new kitchen, bathrooms, adding square footage), a fix and flip loan is the better fit. Fix and flip loans fund both the purchase and renovation, close in 7-14 days instead of 3-6 weeks, and have a simpler draw process. They're designed for investors who buy, improve, and sell.
Construction loans are for building from scratch on vacant land or after tearing down an existing structure. If any of the original structure is staying, you probably need a renovation loan, not a construction loan. Read our fix and flip vs hard money comparison to understand the renovation financing options.
Buying an existing rental? Use a DSCR loan.
If you're buying an existing income property that doesn't need major work, a DSCR loan lets you qualify based on the rental income the property generates, not your personal income. DSCR loans offer 30-year terms at 7-9%, making them ideal for long-term holds.
How to tell which one you need
| Your Situation | Best Loan Type | Why |
|---|---|---|
| Building from the ground up | Construction loan | Only option for new builds on vacant land |
| Buying + renovating to sell | Fix and flip loan | Faster close, simpler process, covers rehab |
| Buying + renovating to hold | Fix and flip + DSCR refinance | Renovate with short-term loan, refinance into 30-year |
| Buying an existing rental | DSCR loan | Qualify on rental income, 30-year term |
| Building to hold as rental | Construction loan + DSCR refinance | Build with construction loan, refinance when stabilized |
Key Takeaway
Construction loans are for ground-up builds. If you're renovating, buying, or refinancing an existing property, there's almost always a faster and cheaper option.
- Renovating to sell = fix and flip loan
- Buying to hold = DSCR loan
- Building from scratch = construction loan
How to Qualify for a Construction Loan
Construction loans have stricter requirements than a standard mortgage. The lender is financing a building that doesn't exist yet, so they need more proof that the project will succeed.
What lenders require
- Credit score: 680+ for most programs. Some go to 620 with a larger down payment and strong compensating factors.
- Down payment: 10-20% of total project cost. If you own the land, the equity can count toward this.
- Detailed construction plans: Architectural drawings, engineering plans, and a detailed scope of work.
- Itemized budget: Line-by-line cost breakdown with actual contractor bids, not rough estimates.
- Licensed general contractor: Most lenders require a licensed, insured GC with a track record of similar projects.
- Building permits: In hand or application in process before closing.
- Cash reserves: Enough to cover the down payment, closing costs, and several months of interest payments between draws.
Mortgage vs construction loan qualification
| Requirement | Mortgage | Construction Loan |
|---|---|---|
| Credit score | 620+ | 680+ |
| Income verification | Pay stubs, tax returns | Same + sometimes more detail |
| Appraisal | Existing property | "As-completed" appraisal based on plans |
| Building plans | Not required | Full architectural + engineering plans |
| Budget | Not required | Itemized with contractor bids |
| Contractor | Not required | Licensed, insured GC required |
| Permits | Not required | Required before closing |
Pro Tip: The most common reason construction loans get delayed or denied is incomplete documentation. Get your plans, budget, and contractor information together before you apply. A complete package on day one can cut weeks off the approval timeline.
Commercial Construction: What's Different
Most content about construction loans focuses only on residential. But commercial construction financing works differently and is often a better fit for investors and developers.
What qualifies as commercial construction
- Multi-family buildings (5+ units)
- Retail or office space
- Warehouses and industrial buildings
- Mixed-use developments
- Hotels and hospitality
How commercial differs from residential
Commercial construction loans are underwritten primarily on the projected income the property will generate once complete, not your personal income. The lender looks at the market demand for the space, pre-leasing commitments (tenants who have signed leases before the building is done), and the developer's track record.
Rates are typically 8-12% during construction, and the loan converts to a commercial mortgage or gets refinanced into a DSCR loan once the property is stabilized (usually 75-80% occupied for multi-family, or anchor tenants in place for retail/office).
Key differences from residential construction loans:
- Down payment: 20-30% (higher than residential 10-20%)
- Experience: Almost always required. Lenders want to see 2-5+ completed commercial projects.
- Pre-leasing: Many lenders require 30-50% of units or space pre-leased before funding.
- Personal guarantee: Often required alongside the project entity.
- Environmental review: Phase I environmental assessment required for most commercial sites.
Why this matters for investors: If you're building a small multi-family project (5-20 units) or a mixed-use building, don't assume residential construction loan rules apply. Commercial lenders evaluate these deals differently. Talk to us about your project and we'll match you to the right program.
Frequently Asked Questions
Is a construction loan cheaper than a mortgage?
No. Construction loans have higher rates (7-12% vs 6-8% for mortgages) because the lender is financing a property that doesn't exist yet. You also pay inspection fees at each draw stage and 1-2 origination points. However, you only pay interest on the amount drawn during construction, so monthly payments start small and grow over time.
What are the cons of a construction loan?
Higher rates, stricter qualification (680+ credit, detailed plans, licensed contractor), more documentation, draw inspections that can slow down the project, short terms (12-24 months), and the risk of cost overruns. You also need cash reserves to cover expenses between draws.
Is it harder to get approved for a construction loan than a mortgage?
Yes. Mortgages need proof of income, credit, and a property appraisal. Construction loans need all of that plus detailed building plans, an itemized budget with contractor bids, a licensed general contractor, building permits, and a project timeline. The lender takes more risk, so the bar is higher.
Do I need 20% down for a construction loan?
Not always. Down payments range from 10-20% of total project cost. If you already own the land, that equity can count toward your down payment. Strong credit (700+) and experienced builders often qualify for the lower end of the range.
What is a construction-to-permanent loan?
A construction-to-permanent loan combines the construction phase and permanent mortgage into one loan with one closing. During construction, you make interest-only payments on drawn funds. When the build is done, the loan converts to a standard mortgage. This saves a second set of closing costs and locks in your permanent rate from the start.
What happens if the project goes over budget?
You cover the difference from your contingency reserve (smart builders include 10-15% above the estimated budget) or out of pocket. For large overruns, you can request a loan modification from the lender, but it's not guaranteed. This is why budgeting with a 10-15% contingency buffer is critical for every construction project.
