An auction for a house it's pretty tricky. You can either win lots of money or you will sell the house for scrap because you will not have many bidders. Another important thing to keep in mind it's that the bank will evaluate the house and of course that they will give you a small number. If the house it's worth 200.000, they will give you 125.000 or something like that. I would suggest you take a loan from a bank that you can trust. Personally, I've been using Finpedia since a friend had recommended me to try it and I satisfied so far. Of course, there's no perfect bank, but you have to find one that's good
