My 5-Minute Rental Deal Screen Framework
One of the biggest mistakes new investors make is spending hours underwriting deals that were never worth looking at in the first place.
After looking at a lot of rental deals, I’ve found that most of them can be filtered out in about 5 minutes before you ever open a full spreadsheet.
Here’s the quick framework I use to screen deals before going deeper.
1. Rent vs Purchase Price
First thing I check is how the rent compares to the price.
For small rentals I usually want to see something around 0.8%–1%+ of the purchase price in monthly rent before I spend time underwriting.
Example:
$350k purchase → ideally $2,800–$3,500/month in rent
If it’s way below that, the deal usually struggles once financing, taxes, and insurance are added.
2. Taxes vs Purchase Price
This one quietly kills a lot of deals.
If the property taxes look extremely low relative to the purchase price, I assume they may adjust after the sale and I run the numbers using a higher estimate.
A deal that only works with artificially low taxes usually isn’t a real deal.
3. Insurance Reality Check
Insurance costs have been rising quickly in a lot of markets.
Before underwriting, I usually sanity check whether the assumed insurance number is realistic for that property type and location.
4. Financing Stress Test
I'll quickly estimate the loan payment using a conservative rate and typical DSCR terms.
If the deal only works at best-case financing, it’s probably too fragile.
5. Cash Flow Cushion
Finally I check whether the deal still produces reasonable cash flow after:
- Vacancy
- Maintenance
- Property management
- Capex reserves
If it barely breaks even on paper, it usually gets worse in real life.
Most deals fail somewhere in these five checks, which saves a lot of time before getting into detailed underwriting.
