Could anyone recommend me a good book on investing in multi family homes? 

My turnovers have tended to come because of someone’s need to relocate for a job or family reason as opposed to any other reason.

Is it a single family house and just renting a bedroom?

Imagine if you had one single-family home.

I'm not a fan of the idea of borrowing money from family members, and have never been keen on the idea of borrowing anything from anybody.

My long term goal at the end of my investment journey is to enjoy the journey, play the long game, and  have enough income from my investments that keeps my family well and financially independent.

I want to put a clause in my lease concerning the charging of electric vehicles at my properties which are at present a number of single family homes in Maryland and Florida. 

I have a few single family homes I'm planning to sell as they become vacant.

What would you suggest to your family in this regard?

I am interested in investing in small multi-family and single family properties.
