⚡ Quick Answer: The Two Methods Lenders Use
📋 Method 1 — Existing Rental (Schedule E)
- • 2 years of tax returns required
- • Uses Schedule E net income (avg of 2 years)
- • Depreciation is added back
- • Best for: landlords with existing rentals
🏘️ Method 2 — Future Rental (75% Rule)
- • No history needed — uses market rent
- • Lender counts 75% of market/appraised rent
- • Appraiser provides rent schedule (Form 1007)
- • Best for: buying new rental property
Method 1: Existing Rentals — Schedule E Calculation
If you already own rental properties, lenders verify income using your federal tax returns — specifically Schedule E (Supplemental Income and Loss). The calculation is not simply your gross rent. Here's the exact formula:
Schedule E Income Formula:
Net Rental Income = Gross Rents
− Operating Expenses (taxes, insurance, repairs, management)
− Mortgage Interest (if property has existing mortgage)
+ Depreciation (added BACK — non-cash expense)
+ Other Schedule E adjustments
= Qualifying rental income (or loss)
📊 Worked Example: Two-Year Average
| Line Item | Year 1 | Year 2 |
|---|---|---|
| Gross rental income | $24,000 | $26,400 |
| − Taxes & insurance | −$3,600 | −$3,800 |
| − Repairs & maintenance | −$2,400 | −$1,800 |
| − Property management (8%) | −$1,920 | −$2,112 |
| − Mortgage interest | −$8,400 | −$8,100 |
| + Depreciation addback | $5,600 | $5,600 |
| = Net Schedule E income | $13,280 | $16,188 |
| 2-Year Average / Monthly | $14,734/yr ÷ 12 = $1,228/month qualifying income | |
⚠️ Key rule: If Schedule E shows a net loss, lenders add that loss to your monthly debts (increases your DTI). Heavy depreciation often creates paper losses — which is why many landlords with strong cash flow fail conventional qualification. This is where DSCR loans become critical. To get pre-approved using rental income, compare lenders who specialize in investor properties.
Method 2: New Rental — The 75% Rule
When buying a new investment property (or converting your primary home to a rental), lenders don't have 2 years of history. Instead, they use Form 1007 (Single Family Comparable Rent Schedule) — the appraiser determines market rent, and the lender credits you 75% of that figure.
📋 Using Form 1007 (Market Rent)
Appraised market rent: $2,400/month
× 75% vacancy/expense factor
= $1,800/month qualifying income
Requirements: appraisal required, property must be investment (not owner-occupied), most lenders require 20–25% down
📋 Converting Primary Home to Rental
Fannie Mae allows rental income with:
- 25%+ equity in the departing residence
- Signed lease agreement
- 75% of lease rent counts toward income
- No 2-year history required in this case
DSCR Loans: The Investor's Alternative When Tax Returns Hurt
If your tax returns show low income due to depreciation write-offs, a DSCR loan bypasses personal income entirely and qualifies you based purely on the property's rent vs. payment ratio.
📊 DSCR Calculation Example
Monthly Rent
$2,800
Monthly PITI
$2,200
DSCR Ratio
1.27 ✅
$2,800 ÷ $2,200
A DSCR of 1.27 means rent covers 127% of the mortgage payment — well above the 1.0–1.25 minimum most lenders require. No W-2, no tax returns, no personal income verification required.
| Feature | Conventional | DSCR Loan |
|---|---|---|
| Income verification | W-2 / tax returns | Property rent only |
| Personal DTI required | Yes | No |
| Tax return needed | Yes (2 years) | No |
| Rate vs conventional | +0% | +0.50–1.00% |
| Min down payment | 15–25% | 20–25% |
| Min credit score | 620 | 620–640 |
| Max properties | 10 | Unlimited |
| Best for | 1–2 rentals, strong W-2 | Investors with 3+ properties or paper losses |
