A deal screener, built on three AI platforms
Personal project · 2026 · Design · Build
A quick profitability check for rental deals: enter price and income, and cash flow, cap rate and cash-on-cash return update live. I built the same tool on v0, Replit and Claude Code to compare how each platform handles a real problem.

The problem
Before full underwriting, investors need a back-of-the-napkin answer: does this property make money, and is it worth a closer look? Most deals get screened out before anyone opens a spreadsheet.
What it does
- Starts from two inputs, purchase price and monthly income, and estimates the rest.
- Shows monthly cash flow, cap rate and cash-on-cash return at a glance.
- Stress-tests returns across a grid of price and rent scenarios.
Comparing AI platforms
I built the same tool more than once to see how each platform’s defaults, constraints and design language held up against a real underwriting problem. The live version runs on v0; this is an earlier build on another platform.
