60-second analysis

One address — a full investment memo.

Every property becomes a dashboard: renovation cost (line by line), monthly revenue, occupancy, ADR, net profit, payback. Each number carries the source it came from and a confidence band — neighborhood cohort where we have one, city or country level where we don't.

Questions

Everything we get
asked, answered.

Still curious? hello@decumara.com
Where do your numbers actually come from?
Revenue and occupancy come from Inside Airbnb listing exports, converted to euros at the ECB rate on the day of the snapshot. Property prices are the thinnest part of our data: only a few markets so far carry portal-sourced prices; elsewhere they are estimates, and the result says which. Renovation costs come from a sourced supplier and index catalogue, priced per city where we hold city data and per country otherwise. Every result names the source it used and the level it fell back to.
How accurate is the renovation cost estimate?
It is an estimate, not a quote. Every line item ships with a range and a confidence band, and the result tells you whether the price came from city-level data, a country baseline, or a wider fallback. Use it to sanity-check a contractor's quote — not to replace one.
Can I use this in a city you don't list?
If your city isn't among the 416 we cover, the estimator falls back to the nearest comparable market with a clearly-labeled lower confidence score. You can also request a city and we'll tell you where it sits in the queue.
Do I need to upload anything?
Just an address. Floor plans, photos, and target finish level are optional but improve confidence. The free tier needs no card.
Is Decumara for investors or owner-occupiers?
Both. Investors lean on Revenue + Renovation. Owner-occupiers tend to use the Renovation Estimator standalone — to know what a fair quote looks like before they sign one.
