Frequently Asked Underwriting Questions
What is a DSCR Loan and how is it calculated?
DSCR stands for Debt Service Coverage Ratio. It divides the Gross Monthly Rent by the Total Monthly Mortgage payment (PITI). A DSCR of 1.20x or higher means the rental income exceeds the monthly debt obligations by 20%, satisfying institutional lending criteria.
How does MamaBroker beat traditional retail banks?
Traditional banks carry heavy branch overhead and sell only their proprietary balance-sheet products. MamaBroker operates as a direct institutional wholesale conduit, accessing capital from 40+ wholesale lenders with lower spreads and customized covenants.
Does this financial calculator send data to third parties?
No. The entire amortization and cashflow engine runs 100% locally in your browser using pure JavaScript mathematics. Zero data is transmitted, stored, or exposed across any external network.
Can I model multiple exit horizons (5, 10, 30 years)?
Yes. The interactive equity chart computes total principal paydown and conservative 3% annual compound appreciation for every month across the full 360-month loan amortization lifecycle.
