💡 What is DSCR?
Debt Service Coverage Ratio (DSCR) = Monthly Rent ÷ Monthly Loan Payment (PITIA). A ratio of 1.25x means rent is 25% higher than your payment. Qualification is based entirely on property rental income — no tax returns or W-2s needed.

This clears the lender at 1.05x, but after typical vacancy, management, and maintenance it nets 0.75x — below 1.00. The lender approves; the deal still loses money each month. Pressure-test it in the Stress Matrix →

IO recast model

Uses the current balance and rate. IO assumes 10 years without principal reduction, then a 20-year recast at the same rate; actual product terms, pricing, and underwriting can differ.

These are scenario changes, not lender terms or approval outcomes. Confirm rent, pricing, and financing assumptions before acting.

The after-tax edge — what other brokers don't quote
≈$85,000sheltered in year one

Most DSCR shops quote a rate. A cost-segregation study reclassifies ~25% of the building into 5/7/15-year property that takes 100% bonus depreciation under OBBBA — roughly $85,000 of first-year deductions on this deal. After-tax return is where serious investors actually decide.

See your after-tax IRR →

Modeled from your numbers — actual depreciation depends on your basis, income, and a cost-seg study; recapture (§1250, up to 25%) and NIIT apply at sale. Confirm with a CPA.

TX is a high-risk insurance market. Get a bindable quote before you commit to this deal — an unconfirmed premium here is a stop, not a footnote. It's the other silent DSCR killer, and the number above assumes coverage you can actually buy.
