Mortgage Payment — The Full PITI Picture
The amortization formula gives only principal and interest. Your real monthly payment adds property taxes, insurance, and — below 20% equity — PMI, which protects the lender, not you. Escrow accounts bundle these so you pay one number; the calculator's tax/insurance fields reproduce the PITI total.
Rate matters more than price at long terms: on $400k at 6.5% for 30 years, P&I ≈ $2,528. At 5.5%, ≈ $2,271 — $257/month, $92,000 over the loan. Points (1 point = 1% of loan prepaid) buy rate down; the break-even is usually 4-6 years of ownership.
Worked Example: $400,000 Home, 20% Down, 6.5%, 30 Years
Loan: $320,000; r = 6.5%/12 = 0.5417%; n = 360
P&I = 320,000 × [0.005417 × 1.005417^360] ÷ [1.005417^360 − 1] ≈ $2,022.62
+ taxes $500/mo + insurance $120/mo (no PMI at 20% down)
Total PITI ≈ $2,642.62 — and the first payment includes only ≈ $289 of principal
Interest over 30 years: $2,022.62 × 360 − 320,000 ≈ $408,143
You'd pay back more in interest than the house cost. One extra payment per year (biweekly schedule) cuts ~6 years and ~$95k of interest — principal prepayment early in the loan is worth the most.
Frequently Asked Questions
How much house can I afford?
Lenders cap housing cost at 28% of gross income and total debts at 36-43% (DTI). On $100k income: ≈ $2,333/month housing max. Better rule: keep PITI under 25% of gross so maintenance (1-2%/yr of home value) and life don't squeeze you.
15-year or 30-year mortgage?
15-year rates run ~0.75-1% lower and the same $320k loan costs ≈ $2,712/month but only ≈ $168k total interest vs $408k. Choose 30-year for cash flow flexibility and invest the difference only if you actually will — the guaranteed 6.5% 'return' of paying off early beats most investing for risk-averse households.
When should I refinance?
Classic rule: refinance when the new rate is ≥0.75-1% lower and you'll stay past the break-even (closing costs ÷ monthly savings — typically $2,500-5,000 costs ÷ $200+ savings ≈ 1-2 years). Also refinance to drop PMI, switch ARM→fixed, or shorten the term.
How does PMI disappear?
At 22% equity it auto-terminates (conventional loans, current on payments); you can REQUEST removal at 20% based on the original schedule, or earlier with a new appraisal showing 20% equity. FHA loans keep MIP for the life of the loan unless you refinance to conventional.

TL;DR
Learn how self-employed buyers and investors can qualify for mortgages using liquid assets or property cash flow.
Getting a mortgage without a W-2 can be tough. This page helps you:
- Understand DSCR for real estate investors.
- Qualify for a home using 'Asset Depletion' logic.
- Calculate accurate monthly payments outside traditional boundaries.
Explain Your Inputs: Why We Need This Data
To model an asset-based or DSCR scenario, we still need standard inputs:
- Property Value & Down Payment: Critical for LTV.
- Interest Rate: Note that DSCR and asset-based loans typically carry slightly higher rates than traditional W-2 mortgages.
Interpretation Guide: Actionable Context
Applying this to your application strategy:
- For Asset-Based: Lenders divide your total liquid assets by the loan term to calculate a qualifying monthly income figure. Use our calculator to see if this 'income' covers the resulting payment.
- For DSCR: Ensure the expected monthly rent of the property is greater than the monthly payment calculated here (a ratio of > 1.0).
Explainable Logic: The Math Behind the Tool
The core amortization math remains identical for non-traditional loans.
The Formula: M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]
The difference lies in underwriting, not the amortization schedule itself.
People Also Ask (PAA)
Can I get a mortgage based on assets instead of income? Yes, asset-based mortgages (or asset depletion loans) allow borrowers to qualify by dividing their total liquid assets by the loan term to create a qualifying monthly income figure.
What does DSCR mean in real estate? Debt-Service Coverage Ratio (DSCR) is a metric used by lenders. It compares a property's generating cash flow (rent) to its debt obligations (the mortgage payment).
Are interest rates higher for non-traditional mortgages? Generally, yes. Because lenders perceive loans without strict W-2 income verification as higher risk, they compensate by charging an interest rate premium, often 0.5% to 1.5% higher.
