    Every cost, line by line

  3. Compare strategies

    Short-term vs long-term

  4. Check the comps

    The data behind the numbers

  5. Get it done

    Agents, lenders, managers

Set a budget. See which rentals in it make you the most.

Tell us what you can put down and where you'd buy. We estimate what new listings would actually make you each month and bring you the few worth a look.

  • “The best real estate user experience”

    I've never been familiar with real estate before but want to start investing. I've used it now for multiple properties. It's been so easy to use, the best real estate user experience. No more car sales people!

    AKAlex KouzaFirst-time investor
  • “My favorite tool to analyze STRs”

    I'm loving it! I have 2 leads I'm working with and it's been helpful to analyze homes they're looking at. I've also used it to help a couple of real estate agents provide analysis to their clients. It's my favorite tool to analyze STRs!

Questions before you try it

Something else on your mind? Write to us and we'll answer.

Every estimate is built from comparable properties: properties near the one you're looking at, of a similar size, that recently sold, rented or hosted guests. Our valuation model gives the closest matches the most weight, and the report shows every one so you can check them. ChatGPT and Claude don't pull those comps for you, so their answer can change each time you ask. Ours comes from the same comps every time. It's still an estimate, so you can change any number if you know better.

The right investment starts with your needs. See what you could actually make.
