There are lots of legal resources available to indigent persons and if you do end up in court, you are far less likely to prevail (and far more likely to pay damages to the tenant who has already taken advantage of you and the seller) when you start with that strategy.Your first step should be to call the housing department of the relevant municipality and ask them what your obligations are.
