So examples: my monthly trip to the apartments to sweep walk ways?

If OP's "friend" can use this opportunity to solve the FTL problem and beyond... that's much more innovative than picking up a part-time job.

When I owned my landscape business years ago before I sold it, on of my clients was a 14 unit apartment complex. 

@Fradel Schaechter props to you for wanting to add value to apartment syndicators.

They look like a brand new apartment and, on a total unit rehab, we don’t spend more than $10-$12k.

I currently live in the DFW area and rent a 1 bedroom apartment for around $876 a month, maybe $1000 with water, electricity, internet, etc included; my lease ends at the end of May.

SFHs and town homes are more common here than multi-family or apartments.

Or, do we look into changing the zoning and combining the lots so we can build a larger apartment building?

Average renter stays 2 years in an apartment 4 years in a house.

I have owned a couple single family rentals, and I am looking to make the move into smaller apartment buildings.I have found a 24 unit building, and I am wondering what the average price per door I should be offering.2 bed / 1 bath apartments go for about $650/MO. here in Michigan.
