Questions from international investors.
Do you speak English?
Yes. We work in English and Spanish, and your client area, reports and video calls can be in English. Legal documents in Spain are signed in Spanish; we explain every clause.
Can I buy without travelling to Spain?
Yes. We view on your behalf, show you each flat by video call, and you can sign at a Spanish notary with a power of attorney granted in your country.
Do you guarantee a yield?
No. We give estimates based on comparable data and show every cost before you decide.
How are you paid?
Our fee is agreed in writing before we start and is paid only by the buyer. We never charge both sides of the same deal.
Can you manage the flat after the purchase?
Yes: refurbishment, furnishing, tenant search and monthly management, long-term, by the room or mid-term.
