@Scott Mac and @Bill B. give good advice.Pull the toilet to see if the subfloor or supporting joists are damaged. 

My wife and I are still in the 'learning phase' as real estate investors, but we know for sure that in the next year (a) we will be converting our primary residence in to a rental, and (b) buying another house that will be our primary residence for 1-2 years so that we can qualify for an owner occupied mortgage.

If you want to do BRRRRs, it's probably better to stick to B or better neighborhoods, as they appraise better and have a higher likelihood of getting your equity out!

Lets assume B-C class neighborhood in Atlanta or surrounding towns.

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620, many blemishes, but should have no evictions in last 2 years.

I live in Hawaii and Los Angeles and will be in LA in two weeks if you want to meet up and process a plan B.   

Quote from @Christina B.: Emotional support animals are covered under FHA.

Class B. in an emerging market.

Gut it out until the end of January with this person and either a) play more hard ball about the vehicle and other stuff b) play it softer and just gut it out with them2.

Absolutely, we have a top Office Broker working with us to find and secure B class office assets.
