The next option is to get the device (you can get on Amazon) that shows the meter for what one unit is pulling versus the other.

Hey Nithin, one of my client's closes today on a next gen home that they plan on renting out the separate unit.

Today we have 540 units in a few states and things are not without challenges. 

The pro development and affordable housing advocates use the term NIMBY, but I suspect it is the rare person that buys in a single family zoned area that would be thrilled to have 17 units (qp16 additional units added) in the lot next to them.My initial protege was the land source on this effort.  

Use of Euro-style wall units for air-con.. 

Start with Reonomy or Costar to identify all the 100+ units in your target market (on and off market) and then see if you can get into direct contact with some owners.

In this case, how many cats do you allow in your units?

Quote from @Jaycee Greene: Quote from @Jeffrey Eschbach: Investment Info:Small multi-family (2-4 units) buy & hold investment.

Just make sure the town is ok with the land being zoned for multi-units, and look into construction costs, financing options, and permits ahead of time.
