In CA you can rent ADUs but can only rent JADUs as a separate unit if the owner lives on the property.  

I don't get the term "DSCR loan"   I mean all loans for 5+ units are based more on the property than the buyer.     

Investment Info:Small multi-family (2-4 units) buy & hold investment.

If you are eligible, you can buy up to a four-unit property with zero down as long as you live in one of the units.

Only one tenant smokes and it fills the other units quickly. 

Multi family can range from about $60k-$125k/unit.

That means that you can buy a property with up to four units, since this is still considered residential.

I live in an apartment with 4 rental units and a studio.
