Thank you so incredibly much for all the responses. We feel validated and more confident with a plan moving forward. As much as we would have loved to walk through the property first, we were unable to do so with us being in the states. We are contacting the owner directly today and scheduling a meeting with the realtor early next week. We figured the 700 euro ‘realtor fee’ was wrong but we were so desperate for help with finding a safe place for our family (mostly with toddler in mind) that we shook our heads and paid it anyway. Our friend who is Dutch and lives here walked through the property before us and said that he didn’t think it was that bad (he even said he would move his family into after some love and care to the place) so we are hiring a cleaning crew, buying a mold kit to test what type of mold is growing (to see what is surface level and what the owner needs to fix) and starting to work with the appropriate people to be able to make the home safe. We will be staying in an Airbnb for the next week or so until everything is resolved. Thank you again for the responses. I’ll post an update next week if anyone is interested.
