Local rent context feeds every analysis, so the biggest assumption starts with data.
From listing to cash flow
Turn Zillow scrolling into deal screening.
CashFlowPanel reads the listing you're already viewing, builds the rental math, and shows whether the numbers deserve a closer look before you spend time on the wrong property.
Works on Zillow & RedfinMarket rent data and local compsReads only the listing you analyze
Works inside the listing pages you already browse instead of sending you to another tool.
Reads supported listing pages only when you ask CashFlowPanel to analyze one.
Open a listing, analyze the deal, adjust assumptions, and review the read in place.
Built for early-stage rental investors
Listing sites tell you about the house. Not whether it's a deal.
Listings show details, not returns
Zillow and Redfin are great for finding properties. They're not built to answer whether the rent, debt, taxes, and reserves actually work together.
One rosy assumption hides a bad buy
A Zestimate-style rent or the 1% rule can make a losing deal look fine. CashFlowPanel surfaces the costs that actually change the outcome.
Made for screening, not spreadsheets
Most investor tools assume complex workflows. CashFlowPanel is for screening on-market rentals clearly and quickly while you browse.
How it works
Three steps from listing curiosity to a clear read.
Open a Zillow or Redfin listing
Keep your normal browsing flow. CashFlowPanel sits beside the listing instead of making you open another tool.
Analyze in one click
Pull price, taxes, HOA, beds and baths, plus a RentCast rent estimate with local comps, without leaving the page.
Review the deal read
See cash flow, break-even rent, cap rate, and cash-on-cash return, built from the rent estimate and your own financing assumptions.
The same panel, two real deals
Watch it call a good deal from a bad one.
These are real CashFlowPanel reads on live Zillow listings. Same financing assumptions, different numbers.
CashFlowPanel read
This deal stands out
At $149,900 with $1,750 projected rent, it clears break-even with $230/mo in cash flow.
Monthly cash flow+$230
Break-even rent$1,439

Real rent data inside
Start with a real rent estimate, not a guess.
Each analysis pulls a RentCast estimate and local rent comps into the same view as price, taxes, HOA, debt, vacancy, and reserves, so the biggest assumption in the deal stays visible from the start.
