small multifamily San Diego County

[Ben Matiella]

Hello all, I have been learning about different real estate investing strategies and am most interested in househacking a small multifamily (2 to 4 units).  I want to ask if anyone on here has been able to successfully do this in San Diego county?  I am not sure how many of these property types (specifically quads) are in supply and SD being a competitive market am not sure if anyone has actually been able to cashflow positive on a property of this type?  

Any thoughts on the matter would be appreciated!
