AI Insights

Use the guide to learn. Use the app to decide faster.

Payment spread

DealCalc AI Insights flags whether the existing payment gives you enough cushion after real operating drag.

Exit risk

If you model a resale, the app checks Projected Profit after cash in and debt carry, not just equity.

FAQs

What should a Subject-To calculator show?

It should show existing debt, Seller Cash, arrears, repairs, Cash Required, Equity at Takeover, Monthly Payment, Monthly Cash Flow, DSCR, and optional resale outcomes.

Why does DealCalc show Rent vs Payment Spread?

It gives a quick read on whether the income has enough room before deeper vacancy, management, and maintenance assumptions are applied.

Can DealCalc model a Subject-To flip exit?

Yes. The app can model a resale path with ARV, Selling Costs, Loan Payoff at Exit, Net Sale Proceeds, and Projected Profit.
