If you’re heart-set on SD, there are several UCSD-area 2br/2ba condos in the 200k range that could be cashflow breakeven (not positive).
I’ve been thinking about the same thing… but then drove by UCSD the other day and they are completing MASSIVE new housing dorms. Wouldn’t surprise me if everyone could live on-campus (finally), which would kill the private rental market.
(Sidenote: I would never try to have a rental around SDSU, but UCSD kids are a different story. In general the state school vs university distinction is pretty valid anywhere.)
