We bought through Atlas with an inspection trip to area. They are estate agents and They guided us and obviously the people we used and continue to use such as solicitors were those they took us to. We bank with Bankinter our solicitors whom we pay commission to ensure all our deeds wills and original nie documents are kept safe and continue to advise us. We have insurances with Mapfre.
Most important is that You must have good solicitor we use Aroca Sequirer. They are based at Punta Prima . They speak many languages with excellent English.
I believe inspector homes offers support on here as an estate agent . There are people on site who also work for Urmosa and I believe you can access info on the Urmosa site.
Good luck
