How your analyst works
Three minutes between the listing and a defensible decision.
01
We check the listing against the official registers
Floor area and age against the Cadastre, energy certificate against the ICAEN register, asking rent against the declared rents in your census tract.
02
We compute the legal rent and the real return
Legal maximum rent under the official SERPAVI methodology. Your region's transfer tax (ITP), the income tax for your situation, vacancy months and every cost the portals ignore.
03
We give you the verdict and your number
One figure: the Total Return (IRR), including leverage, neighbourhood appreciation and taxes through to the sale. We compare it with the area average so you can see at what price the deal becomes attractive.
We don't opine. We cross-check official registers.
This analysis cross-references 36,000 census tracts and millions of rents declared to the Spanish tax agency. Every figure carries its source, so you — or your bank — can verify it.

For serious buyers
“At this price, the return falls below the area average.”
That is a good analysis too. CasaROI is built for people buying their second or third rental flat: it tells you what a good adviser would, with the sources in front of you, before you sign the deposit contract.
