Sounds like my fiancee; she's right there with the whole pretty-ifying things and whatnot.
However, I've been very focused on getting the most notable issues (found on the inspection, and noticed personally) resolved first. What I call "functional" fixes, e.g. things that I know will cause damage down the line.
So far we've done gutters, had the sewer lines scoped with a camera, and while the basement isnt great, it was definitely retrofitted with a sump and drainage system by professionals at some point previous. Electric is new as of 2004 (looks like it was gutted as a result of a small fire) and all work was permitted and inspected by the city.
On the water front, we're at a low point in the neighborhood, so I'm addressing that right now (the city has a water management program called "RiverSmart" that allows you to get remarkably marked down landscaping / dry wells / rain gardens via associated contractors), so we're actively pursuing that now then we'll re-review our situation on that front. No obvious water damage is present, just evidence that it's been an issue at one point or another.
Let's see here.. lots of fixes past that that are mostly cosmetic. Two bathrooms and a kitchen that were totally redone by the previous owner in a way that's embarrassing at best, and ugly as hell at worst (but functional!). Old windows across the board.
Eventually I'd like to get each window replaced, full-frame, but doing that room-by-room while not replacing the metal siding at the same time seems to be somewhere between "challenging" and "impossible". Perfect world would be to do a bathroom gut in the worse condition one, replace window full frame while NOT replacing siding, and doing that room by room. Then eventually doing a whole new siding job.
Ahhh, so much. Nonetheless, function and protection from future damage has been to foremost concern. Cosmetic is annoying, but not much else.
