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 — no copying addresses into a separate calculator, no re-typing numbers into a spreadsheet.
Works on Zillow & RedfinMarket rent data and local compsReads only the listing you analyze
Reads the live listing
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 screening rental deals
Listing sites tell you about the house. Not whether it's a deal.
Same house. Two verdicts.
The only difference is the rent number. An optimistic guess flips the verdict on the exact same deal.
Optimistic rent guess$2,400/mo+$310/mo cash flowLooks like a winner
Rent from local comps$2,050/mo−$40/mo cash flowLoses money every month
CashFlowPanel starts from local rental comps and the costs that actually move the outcome — so a guess never gets to call the deal.
Listings show details, not returns
Zillow and Redfin find the house. They can't tell you whether it pays.
Deal calculators live in another tab
Other analysis tools make you copy the address, switch tabs, and retype the numbers — for every single listing.
How it works
Open the listing. Click once. Read the verdict.
A full deal read in less time than it takes to flip through the listing photos.
Open a Zillow or Redfin listing
Browse the way you already do. The panel sits beside the listing, ready when you are.
Analyze in one click
Price, taxes, HOA, beds, and baths come straight off the page, with a rent estimate built from local comps.
Read the verdict
Cash flow, break-even rent, cap rate, and cash-on-cash return — plus a gauge showing the rent this deal needs to work.
Under a minute per listing, including second thoughts. Obvious passes take seconds.
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.

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. Pro Deal Reports plot the comps on a map around the property so you can sanity-check the estimate street by street.
RentCast estimate$2,400/mo
Low$2,125
