Free Houston deal calculators
The same engines that run inside Slatebeat, opened up and free to use. No signup, no email, no limits — Harris County property taxes, Texas insurance loads and current hard-money terms are built into the defaults, because a calculator that assumes a 1% tax rate will lie to you here.
Flip Screener
Maximum allowable offer
Set ARV and rehab, get the highest number you can pay and still clear your target. Models what actually eats a flip: a 95% exit, hard-money points and interest on a drawn balance, and the months you didn't plan on. If the ask is above the MAO, you walk.

Cap rate, DSCR, investor bid
The same house priced as a rental instead of a sale. Cap rate, lender DSCR, what a yield buyer actually pays at each target cap — and the rent-to-price ratio that replaces the 1% rule in a county where taxes run double what that rule assumed.

Because the math is not the hard part. Every number here is arithmetic anyone can do in a spreadsheet — what takes the time is knowing which assumptions are honest for this market, and then finding the data to fill them in. The assumptions are baked into these tools and documented on every line. The data is what an account is for.
