What our users say
“We bought a flat in Madrid directly from the owner. What we liked most was having the earnest money contract ready the same day, without having to find a separate lawyer.”
“I'm a seller and I didn't pay anything. My buyer signed up, generated the contract with our details and we both signed it from our phones. Much simpler than I expected.”
“We were worried about the utility transfer because it was our first purchase. Having the checklist with everything we needed to do really took the stress away.”
“I used the mortgage comparison tool and the notary finder. I didn't know the buyer chooses the notary by law. That alone made it worthwhile.”
