Hopefully you kept really good records and didn't mix the money into personal accounts.

Property mix of three buildings. one in 1980 and other two prior 20 years, all connected now with connecting walls.

I have a single family home that is in a mixed-use area which currently allows for a 60' apartment building but will rezone to allow 70' in about 2021. 

@Scott Passman emotions and money don't mix well, so we have to look at data.

Also 7 cap is quite low for mixed use but don't know which area either...

Its a Mixed use property with commercial space on the first floor and residential on the second floor.

I worry that you may be mixing your want and desire to help folks with being a landlord.

What I've found is a 36,000 sf mixed-use property, all-brick, built 1914. 7 huge garage bays in 2 separate wings of the building, a storefront that needs serious work, one finished 2-bedroom apartment, and 2 upper floors that are completely gutted and ready to build out. 6 electric meters in the photo, likely shared oil heat for the whole place, all new windows, new roof, new sprinklers, masonry looks OK from pics and street view. 

A List Broker can offer suggestions to optimize a list for your area, including some of the newer motivated owner occupied segments to mix. in This can be good since as @Brian Midden says, in most markets  Absentee Owners are getting a lot of offers.You might be able to get better pricing than with ListSouce

What it all looks like when they leave is an interesting consideration.I have very mixed feelings about our surveillance society.
