Perhaps if they can get to it via bottom by removing baseboards.

Take some time to get to the bottom of what is motivating you.

@Blaine Conley she bought those back at the bottom of the market IIRC. 

You will need most likely a minimum of $1,100/unit (assuming the $3,315 rent roll is for all 4 units) to even begin looking at this as potential for a rental.Because you are still missing some factors, it will only hurt the bottom line.

I've only included income for the two apartments. the bottom floor is zoned for commercial, that will be bonus money.

Get a neutral lawyer involved if you want to minimize the pain and somewhat control the outcome. 

I’ve seen on BP that the common denominator says the bottom dollar would be $100 for multi family and $200 for SFH.

You have to look at where prices are today in relation to their 2006 high and not how much they've gone up from their bottom.

I have come across an off market property that has a finished top level, and the bottom level is a converted finished living space without pulling permits.

Sometimes you'll buy at the top, other times at the bottom.
