Hi. To make long story short, the house we are in, we had verbal agreement with owner we were supposed to be buying the house. The house needed repairs and improvements which we have done. the repair and improvement cost was supposed to be used for our down payment. We have put alot of money and labor into this house. Now we just found out he has put it up for sale for double what he was going to sell to us for. can we file a lien for the repairs and improvements we have made. is there anything we can do, We are current on our rent, I'm furious he is doing this after we just put all this money into it.
