Two, even if the city would allow it, the entire neighborhood would hate you, including the university, the local residents, the students & the large property owners.

Two years later I bought another single family with 5% down conventional mortgage and turned my former residence into a rental. 

Their location is more important than houses.The biggest problem with house rentals is that there are not enough units at one place and they usually costs more than you think to turn them over for a new resident. 

@Aditya Namjoshi - see notes below.1) The BRRR approach is typically used for your primary residence so living in SoCal and investing out of state isn't possible (I don't want to sound negative).

We show a majority of our homes to an interested resident. 

It looks like if I want to buy, since I am now classified as a non-resident, I would be looking at a minimum 35% down payment.

Our situation in a broad stroke:We will be completing an addition on our primary residence.

My situation: I have one rental that was my personal residence before getting married and moving into my wife’s house.

However, as a non-resident foreign national, they don't have an SSN. 

After a year of primary residence, can I jump right into an FHA loan with another quadplex?
