I'd forget about making your money back and figuring out how to triage the situation and lose the least amount possible. Your options range from sell as-is to total makeover. Your best bet is probably spending enough to have a functional, acceptable house (that is, meets inspector approval, and is at least presentable to buyers) without going overboard. For example if the "second floor bath needs work" means it needs a remodel, not a gut job, a coat of paint and maybe some vinyl flooring will have to do. A missing kitchen would be unacceptable. However a complete kitchen with cheap materials or with recycled / reused materials (a la the recycle stores that Habitat for Humanity run) would be acceptable. Spending 20k on nice tile and appliances would be throwing money away. At your price level people respond to newness more than quality, so even a cheap new countertop for $100-200 will do. Another example, the windows in our house are varying ages, I replaced the three worst ones this year for only $129 each. It's a complete transformation, even though they are low end windows.
Mandatory: lights work, water works, HVAC works, no peeling paint, no noticable leaks, no smells, nothing that draws the eye.
I live in the same type of house as you, though we will not lose nearly as much. It is a mental and physical drain thinking about the chain around your ankle. Personally, my biggest issue is I have no desire to do things half-assed, yet to get everything done cheaply, that is the route I have to take. Good luck!
