See your best and worst property at a glance
Net profit per door — after the mortgage — across your whole portfolio. Monkey Riot turns 40 rent statements and invoices a month into one number that tells you which property to fix first.
Only 50 founding places · free trial at launch · built by active landlords.
Illustrative — your numbers, your portfolio.
You own the portfolio. The spreadsheet owns you.
- ✕ 22 rent statements and 15 invoices landing in your inbox every month.
- ✕ A tab per property, a formula you're scared to touch, and a gut feeling instead of a number.
- ✕ No idea which property is quietly losing you money after the mortgage.
One final number per property. Ranked best to worst.
Monkey Riot reads what you already have and gives every property a Property Efficiency Score — so the decision jumps off the screen instead of hiding in row 47.
Chaos in. Clarity out.
Drop it in
Your spreadsheet, a CSV, or a Google Sheet link — messy is fine. No reformatting, no re-keying.
It ingests
Monkey Riot reads the labels and lines up rent, costs and mortgage per property — automatically. You can also connect Gmail so rent statements and invoices import from your inbox (read-only).
You see the snapshot
PES for every door, best and worst ranked, and the one property costing you money — at a glance.
Bloomberg for property investors.
Property Efficiency Score
A single 0–100 score per property, so performance is obvious without a finance degree.
Profit after the mortgage
Real cash left per door each month — not gross yield vanity metrics.
Spot the money pit
See which property eats its profit in maintenance before it eats your year.
Where your risk sits
Know how exposed you are to one tenant, one street, one lender.
Costs creeping up
Catch the slow rise in costs across the portfolio before it hits your margin.
The number, live
Portfolio cashflow that updates as the data lands — no month-end scramble.
Before you ask
Do I have to leave my spreadsheets? +
No. Keep working however you work — drop the file in and Monkey Riot reads it as-is. We meet your data where it lives.
Is my data safe? +
Your portfolio is yours alone — isolated per account, encrypted, hosted in the UK/EU. We never sell or share it.
Who is it for? +
Hands-on landlords and investors with a handful to a few dozen properties — people who run the portfolio themselves and are done living in a spreadsheet.
How do I get started? +
Sign up, import your portfolio from a spreadsheet or add properties manually, and Monkey Riot scores them straight away. It takes minutes.
What will it cost? +
Simple monthly pricing that scales with your portfolio. Start with a free trial — no card required.
