Paste a link from idealista and get a free property audit in seconds: know the real price of the apartment, the real tax cost and hidden risks and liabilities no agent would ever tell you.
Olá Product Hunt! I'm Mikhail, maker of SirJohn.
Buying a home in Portugal usually means trusting the asking price, the agent, and your gut - while the deposit is non-refundable.
Our team wanted a second opinion that isn't selling you anything.
Paste an Idealista link and SirJohn runs a full audit in seconds:
Know the apartment's real price down to the penny with our accurate AI model trained on years of data.
Uncover hidden liabilities and tax costs (that no real estate agent will tell you).
Run 36 risk checks on the property—from noise and flood risks to radiation exposure.
Check the rental license and calculate your potential yield on the fly.
Uncover hidden secrets behind the district's infrastructure.
It's free and doesn't require a signup.
Would love your feedback, especially from anyone who's bought (or is buying) in Portugal. AMA!
