# How to Analyze a Rental Property in 15 Minutes | KREC

## Screening a Rental Deal in 15 Minutes: The Lender's Quick Test

Most rental deals can be ruled in or out in about 15 minutes. Here's the quick test, plus the costs that turn a DSCR into real cash flow.

Short answer

Screen a rental in four steps: estimate market rent from comparables, estimate the full payment including taxes and insurance, divide to get the DSCR, then subtract vacancy, repairs and management to see real cash flow. A deal can pass the lender's DSCR test and still barely cash-flow, so check both.

Key points

- Rent ÷ full payment = DSCR.
- Then subtract vacancy, repairs and management.
- A passing DSCR doesn't guarantee cash flow.

### The four-step screen

1. **Rent.** Pull three to five comparable rentals nearby.
2. **Payment.** Estimate principal and interest at your down payment, plus taxes, insurance and any HOA.
3. **DSCR.** Divide rent by the payment. Around 1.0 or better is in range for many programs; see [what DSCR you need](https://keyrealestatecapital.com/blog/what-dscr-ratio-do-you-need).
4. **Cash flow.** Subtract vacancy, repairs and management from what's left.

**Deal sheet: Quick screen, illustrative**

|  | Amount |
| --- | --- |
| Market rent | $2,400 |
| Total payment (PITIA) | −$1,950 |
| DSCR | 1.23 |
| Vacancy, 5% of rent | −$120 |
| Repairs, 5% of rent | −$120 |
| Management, 8% of rent | −$192 |
| **Monthly cash flow** | **$18** |

This deal passes the DSCR test at 1.23 but cash-flows just $18 a month after realistic costs. That's a thin margin for a long hold.

### Quick fixes when a deal is close

- Negotiate the price, which lowers the payment
- Put more down or buy down the rate; see [what half a point does to your payment](https://keyrealestatecapital.com/blog/half-point-rate-difference)
- Self-manage, if you're local and willing
- Pass, and keep looking
