... do try to get estimates for all the 'shortcomings' of the home. Again, you can use that as ammunition for your bid price. Just don't be disappointed if the Seller takes the position that all, or a lot, of your 'items' are cosmetic. Electrical issues that need to be brought up to code and water leaks and the like are the KINDS of things that are necessary to make a home habitable, AND safe. Keep throwing that at him.
I, too, will say that sometimes, we get over-zealous. That's not meant to insuate you HAVE to listen to us. In most cases, our 'advice' speaks for itself but weigh it with your OWN position. If you want the home that bad, do buy it, but be thoroughly aware of its 'shortcomings'. I think that's all we're saying.
I wish you the best and in due time, I'm sure someone will be here to help you if you need it.
