Scott and Ron are correct. The buyer is approved first. Then they will go out and the VA appraiser will evaluate the home. unfortunately there is no home attached to your question so it is hard to see why you are asking. The VA is pretty strict about the home being habitable (you can move in and live there) when you buy. For example no broken windows, plumbing must be working, must have an oven/range that works and the Heat works. Now if the home needs quite a bit of work you could always look at doing a FHA 203K loan where you can get extra funds for repairs.
So the best bet is as Ron states speak to a lender and if looking for a VA or whether a FHA 203K loan.
Hope this helps,
