Value adds are always a great opportunity to generating additional more money.If you have extra space on your property, consider applying for an ADU. 

Something like a house hack, rent out extra bedrooms in your unit, rent by the room, mid term, short term rent the owner occupied unit on busy weekends (and go stay with friends/family)...get really scrappy.

Or add an extra garage.  

I want to upgrade my house up a notch in the couple years and get a couple little extras like that.  

Yesterday, the landlord stated that it was their impression that we had agreed to painting not only the two rooms but extra rooms as well and now they are saying they are going to void the clause and raise the rent back to $3200, or we have to paint extra rooms not agreed upon.

- Rent out the extra bedrooms in your unit to roommates or for even higher rent on Furnished Finder.- Rent out the other unit as STR or MTR for max cashflow - which will require you to become an expert at those businesses.- Learn how to do your own repairs & rehabs to save money now.

Insurance is expensive, there is a lot of extra maintenance like painting or electric in common areas that don't apply as much with smaller units. 

Highlight the “family-friendly” perks, like extra beds, pet policies, and flexible terms.

The tenants have paid and if someone is thinking about moving out then an extra surcharge that hits if they aren't out in time for us to turn the place for a lucrative AirBNB short term rental can help massage the move out timing.That said with MTR we do not have the cleaning costs that eat up a lot of STR gross, and its lower hassle in some ways.  

But it fits with the current portfolio I hold in that town and doesn't take much extra work for the returns I get.
