cashpumpkin Start free trial
A Chrome extension for rental investors

Know if a rental pays before you make an offer.

Paste a listing and Cashpumpkin shows the real cash-on-cash return, with every cost the listing leaves out, and the most you can pay and still hit your target.

No account. No credit card. Then $9/month, cancel anytime.

The Cashpumpkin workspace: a table of saved deals with cash-on-cash return, cash flow and max offer for each, filed by state and city.
The real number

A listing shows rent and a mortgage. You also pay for everything else.

Same house, two ways to look at it. Cashpumpkin fills in the costs a listing never mentions, using public data for that ZIP code.

How it works

From listing to answer in about ten seconds.

Paste a listing

Copy the listing text or link, or just type the price, ZIP and bedrooms. Cashpumpkin pulls out the facts it needs and throws the rest away.

See the real return

Rent for the area, this week's mortgage rate, the property tax a buyer actually pays, and every cost a listing leaves out. Then your max offer.

Track every deal

Each paste becomes a saved deal, filed by state and city and ranked by return. Move the good ones through your pipeline to an offer.

What you get

A workspace for rental deals, not just a calculator.

Plus cash flow, cap rate and DSCR for every deal, scored against your own target.

Questions

Good to know

Do I need to create an account?

No. Install the extension and your 7-day trial starts right away, with no sign-up, email or card. If you decide to subscribe, you enter your email and card on a secure checkout page run by ExtensionPay and Stripe. You'd use that same email to unlock Cashpumpkin on another computer later.

What happens when the free week ends?

Cashpumpkin asks you to subscribe for $9/month to keep analyzing. Your saved deals stay on your computer either way, and you can still download them all as a CSV.

How do I cancel?

Open Cashpumpkin, go to Your numbers → Your plan, and click Manage or cancel subscription. You can cancel anytime and you won't be charged again.

Where do the rents and tax rates come from?

Public government data: HUD's Fair Market Rents for rent, US Census data for property tax rates, and Freddie Mac's weekly survey for mortgage rates. HUD's rent is on the conservative side, so you can always type in your own.

Does it work with Zillow, Redfin or Realtor.com?

You can paste a listing's text or link from any site. Cashpumpkin reads only what you paste, on your own computer. It never opens, scrapes or overlays listing websites, and it doesn't use their estimates.

Can I get sold comps?

Yes. Paste a page of sold homes you've found and Cashpumpkin reads the comps from your paste, or type in your own.

Which browsers and markets does it support?

Google Chrome (and Chrome-based browsers like Edge, Brave and Arc) on a computer. The built-in data covers the United States.

Stop guessing. Start with the real number.
