COMPLETE RENTAL UNDERWRITING
This analyzer follows the same operating order as the DLS rental engine: scheduled rent minus vacancy gives effective income; operating expenses produce NOI; amortized debt service then produces cash flow, DSCR and cash-on-cash return. Cap rate always uses the all-in basis, not just the purchase price.
CRIM Property Tax Estimator
Estimate the annual CRIM contribución from the assessed (1957) value, exemption and your municipality's rate — before you buy, bid or sign.

BRRRR Calculator
How much cash you pull back out at the refinance, and whether the property still cash-flows after.
