Fort Worth Local Market Note
Informational onlyFort Worth has grown into one of the largest U.S. cities while keeping entry prices below neighboring Dallas, drawing investors to neighborhoods like Polytechnic Heights and the Near Southside. The Alliance corridor's logistics employment supports steady workforce-housing demand. As across Texas, effective property tax rates near 2% are the biggest line item to verify before closing.

How to Use This Rental Property Calculator (Mini Guide)
This is a quick underwriting pass to estimate cash flow and NOI using vacancy, reserves, and operating expense assumptions — so you don’t buy “paper cash flow.” These defaults are pre-filled for Fort Worth, TX. Always replace them with your real numbers when you have them.
What this calculator measures
It estimates: monthly cash flow, NOI (income after operating expenses), and simplified returns.
It’s meant to answer: “Does this deal survive real expenses and still cash flow?”
Inputs that matter most (verify these first)
Market rent (not seller rent): validate with comps.
Vacancy: even great rentals go vacant — 0% is unrealistic.
Taxes + insurance: often change after purchase and vary by location.
Reserves (maintenance/CapEx): prevents ‘cash flow’ disappearing after a roof/HVAC/turnover.
3-minute underwriting workflow
Enter purchase price + financing terms.
Enter market rent + realistic vacancy.
Enter taxes/insurance (or start with defaults, then refine).
Keep reserves non-zero unless you have strong documentation that it’s truly turnkey.
How to interpret the output
If cash flow is barely positive, one repair can flip the deal negative.
NOI helps compare deals across markets. Cash flow tells you if the deal pays you monthly after debt.
For accuracy, treat rehab, closing costs, and initial reserves as part of your cash invested.
Next steps
If it fails: don’t force it — price is likely too high or rent is overstated.
If it passes: stress test vacancy and expenses, then build a fuller 5–10 year model.
