Solve both payment and cash constraints together, including price-dependent taxes and loan-dependent PMI under your own DTI assumptions.
Solve both payment and cash constraints together, including price-dependent taxes and loan-dependent PMI under your own DTI assumptions. Supporting calculations and limitations are shown alongside the result, with relevant local examples.

Front-end capacity is monthly gross income times the entered housing-DTI limit. Back-end capacity is income times the entered total-debt limit minus existing monthly debt. The lower of those two limits is used.
When taxes are entered as a percentage, they depend on home price. Loan-dependent PMI and percentage down payments can also vary with price. These amounts are recalculated inside the bounded price solver rather than subtracted afterward as unrelated fixed costs.
Required cash equals down payment plus the price-based closing allowance and any fixed closing cash. A candidate price must satisfy both this cash limit and the total monthly housing ceiling.
PMI is an explicit user-entered fixed monthly amount or annual percentage of positive loan principal. No lender-specific rate, eligibility condition or automatic 20%-down cancellation rule is invented. A zero loan has no modeled PMI.
No. The alternative rate is applied to a separate solve with the same income, costs, cash and DTI assumptions. The calculator also shows housing cost at the original estimated price under that stress rate.
No. These DTI thresholds are user-configured planning assumptions, not universal lender requirements. The solver is bounded to 100 bisection iterations and a $10 billion software ceiling; property values, costs and underwriting require independent confirmation.
