I manage properties and one of my owner's favorite sayings is "You can't rent a good house in a bad neighborhood." Very true.
Don't buy a house with fuses...if the electrical hasn't been upgraded to a circuit breaker box, make sure you get an estimate on how much it's going to cost to put one in. This can get mucho spendy if too much has to be ripped out, rerouted or permitted.
Termites aren't too big of a problem here, but carpenter ants are, they can make a real mess.
Check the water pressure, if it's too low everywhere in the house, you might be looking at a new water line or if it's just the hot water, the water heater may be clogged with gunk. Water heaters aren't a huge deal though.
Don't buy a house with a flat roof....you're from Portland, you know why, LOL
If the bathroom is all tiled, especially the shower surround and the tub is a mess, pulling the tub can be a major pain. I can give you the name of a good company that puts an insert into the tub rather than refinishing it. Saves you money, hassle and refinishing just doesn't last, especially if you have kids.
I'm sure I'll come up with some other stuff if I think about it. LOL
Oh, and I know a couple of good realtors if you need one. And no, I don't get a commision
