Mike, loved your story about the kitchen and car!
I would look into doing the foundation work and the bathrooms. Most buyers balk if there are structural issues, with a foundation being a major concern. Re: bathrooms, I would have your agent come in and give you counsel on what he/she is seeing in homes these days. Just keep it neutral for the next buyer. You don't have to spend alot, but for the bathrooms, they do need to be nice and of a cohesive design and color.
Without knowing the extent of what needs to be done, if you are finding it unaffordable for yourselves to do, keep the quotes from the contractors you have had in, so that these numbers can help price the house when you go to sell it, or can be used for negotiation purposes during the inspection contingency.
