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.

The most you can bid and still hit your minimum profit. Write it down before the auction — never bid a dollar past it.
Fix & Flip Calculator
Net profit and ROI from purchase, rehab, holding, closing, ARV and selling costs — the costs beginners forget, included.

A fast, defensible rehab number before you make an offer: per-square-foot base plus kitchen, baths, roof and contingency.
