Newbie Question 1st Property
If the house I would like to purchase is seller financing, should I negotiate the closing costs or down payment if required. I would like to buy the property with as little money out of my pocket. Can you submit an offer like that. The house is a bank owned property that is selling for 57,500. It is worth 76,390. 
Everything is negotiable. Whether they accept or not is a different story.
If this is a bank owned property, they will not likely be willing to finance it. Usually the bank just wants rid of the property, tho sometimes they will consider financing.
