W/ all due respect to Mr.

Life is too short to waste time hating anyone.4.

There are some that are great, unfortunately there are some that will waste your time.

he removed part of a load bearing wall.  

But if you are gonna rent upstairs and live there, start saving as much money as possible from your end since you should be living almost free don't waste the next 5 years not planning/working towards your next deal 

For example cat pee can indicates the need to replace carpet and even possibly walls or sub-floor.

I had experience with a basement that had problems that were hidden behind wall and purchase was in the summer.
