Generally if the buyer is going to occupy the owner/renter ratios aren't as important (might just be FHA but not conventional), and if the buyer is going to keep it as a rental then also not a deal breaker. 

The reality is they probably won’t put as much TLC into the property as you would, but I don’t think it’s a deal-breaker for expanding your portfolio.

But if, while unhappy, nothing you've found is a deal breaker i would go ahead with an inspection.

., one of the many relevant laws is Equal Housing Opportunity (EHO) which forbids discrimination on many bases including - you guessed it - physical disability.If you intend to discriminate against a U.S. citizen who otherwise meets the income requirement you have set up in your business, you'd better be able to defend that action in front of a circuit court judge.By the way: EHO is a Federal statute.

Switch the breakers one by one to isolate that particular line.

I have to make sure that the breakers are accessible to both units 24/7 (they are now on the outside of the house; so no problem there).

Circuit breaker has flipped (basic I know, but you didn't explicitly say you checked the breaker so its worth double checking)2.

The framing is most likely rough cut so the drywall will need to be floated, when the walls come down you need to upgrade the electrical since I can also bet the electrical is not properly insulated, you need GFCI by sink, you have to have an arc fault breaker on the bathroom outlets and switches and those need to be on their own breaker by code. 

I'm particularly concerned with things like what's acceptable for egress, and when is moving a breaker box worth it.

I tried calling Circuit court and they do not have specific list.
