Seller Net-Proceeds Calculator
Punch in a sale price and see exactly what lands in your pocket after every deduction — no surprises at the closing table.
Grandmother House Scorer
The holy-grail deal filter, as an app — score any listing against the grandmother-house method: good bones, maintained systems, dated cosmetics.
HELOC vs Cash-Out Refi
You need cash out of your house. One question: is a HELOC or a cash-out refinance cheaper for you? Punch in both and see.
1031 Deadline Tracker
Sell an investment property and the IRS hands you two clocks: 45 days to identify a replacement, 180 days to close. Never miss either.
Drive-for-Dollars Logger
Spot a distressed house, log it in 30 seconds from the driver's seat, and build the hit list your mailers and skip tracer will work from.
Sell or Keep?
Moving into a new place and wondering whether to sell the old house or keep it as a rental? Ten-year wealth math on both paths, the rent that flips the answer, and the capital-gains clock you're racing.
Rent Collector
The full landlord stack — properties, tenants, automatic monthly rent charges, late fees, a tenant payment portal, and P&L reports with CSV export.
Reno Budget Builder
Room-by-room rehab budgeting with investor-grade presets, contingency and GC markup built in — then the 70% rule against your purchase price to see if the deal still works.
Bedroom Bump
Student houses rent by the bedroom, not by the house. Underwrite any rental both ways — as-is vs. with bedrooms added — and see if the conversion is a value-add or a fantasy.
Property Tax Appeal
If your assessment is higher than what the house would actually sell for, you're paying tax on phantom value. Comp-based math on whether you have a case — plus the appeal letter, written for you.
Rent-Raise EV
A rent increase is a bet. Enter the raise, your honest walk-away chance, days-to-fill, and turnover cost — expected-value math tells you if it wins, breaks even, or bleeds you dry.
Schedule E Expense Tracker
Log every rental expense against the real IRS Schedule E categories, snap receipt photos, and export a CPA-ready CSV at tax time. Built with JavaScript.
Rental P&L Tracker
See which properties make money and which ones are lying to you — monthly P&L cards, a 12-month cash-flow trail, and wax-seal verdicts from CASH COW to BLEEDING. Built with JavaScript.
Estimated Tax Planner
Quarterly taxes without the April surprise — estimates your annual bill, compares it against the safe harbor, and lays out four penalty-proof payments with due-date reminders. Built with JavaScript.
