Frequently Asked Questions

Non-QM loan types?

Bank statement: 12–24 months bank statements as income proof. Self-employed friendly. DSCR investor: NOI / debt service ≥ 1.0–1.25x qualifies, no personal income docs. Foreign national: passport, foreign bank statements. Asset-based / asset depletion: liquid assets divided by 60–180 months. Profit & loss: CPA-prepared P&L only. ITIN: alternate ID for non-citizens. All carry rate premium 0.5–2.0% vs conforming, plus higher down (15–25% typical). Lender pool narrower.

How does this debt analysis fit a workout strategy?

Workout, default, and recapitalization decisions depend on the gap between in-place debt and current asset value. Lenders evaluate cure cost, foreclosure timeline + cost, broker price opinion (BPO), and borrower equity. Borrowers evaluate equity in the property, refinance feasibility, and forbearance economics. This calculator provides one input to that multi-factor decision.

Discounted payoff (DPO) vs forbearance vs deed in lieu?

DPO: lender accepts less than full balance to avoid foreclosure cost, common with non-recourse and underwater assets. Forbearance: payment deferral 6–18 months, balance accrues, useful when value will recover. Deed in lieu: borrower transfers title to lender, faster than foreclosure but lender takes full risk. DPO often best when borrower has new capital + lender wants quick exit.

Special servicing dynamics?

CMBS loans transfer to special servicer at default or maturity default. Special servicer compensation aligns with workout, but timeline is 6–24 months and fees stack ($25–250k+ in costs). Whole-loan and balance-sheet lenders move faster but with less flexibility. Bridge and debt fund lenders most flexible. Time-to-resolution and total friction cost should be weighted in any borrower scenario.
