Since it is highly unlikely a loan can be obtained for that amount through a conventional lender, you will be making a cash purchase. As Brian indicated, your costs are small a few hundred, five hundred at the most.
However, you fail to reveal what you are buying, (a house for $35,000 suggests this is only the beginning of your real costs) the situation of the property, what the contract states and what the seller may be imposing on you.
Based on what little is revealed...a few hundred should do it.
There are a lot of folks on Truia inquiring if there is homes availble for $35,000. are there more?
