Thanks, Kate! Good luck with your renovation project and the cat odor -- it's a tough thing to deal with! The last tenant was there for over 12 years, and her health declined over the last few and she simply was not able to keep up with the demands of her home and her multiple cats. She's a family friend, so we tried to be as understanding as possible, but we just didn't realize how bad it was until she moved out.
When we sold our other childhood home 7 years ago, we did very little to it -- replaced some old light fixtures, painted, and that was about it, even though the kitchen and baths had never been updated since it was built in the 70s. It sold very quickly nonetheless. This one was a little tougher, but it's an older house with more issues!
