How do I find out if its an A, B, C, or D class neighborhood in my town? 

$800 lot rents usually mean a tenant class that can afford to buy.

Property Class: Looking more at class B now vs Class A or CAgreed, I think B will be the strongest. 

With depreciation, cash out refis, and 1031 exchanges, real estate income is in a class all its own.Ps.

@Adam Tafel and I teach a class on the subject.

Is it more of a C or D class neighborhood?

Plus a lot of online classes about landlord-tenant law, about operating rentals, and investments in general.

Back of the envelope, there's plenty of margin for cashflow.Most of my experience has been investing in B and C-class multis in Providence, RI where units are closer to $80,000 a unit in decent condition, renting for $900 a month.

Last I checked, they still had an income and net worth test, but even lower middle class people could qualify.That being said and to Chris's point, regulatory filings and operating costs on such a venture can add up. 

Here in Oakland, and the Bay Area in general, prices have consistently gone up over the last 9 years or so, but they had slowly started to flatten.....and that was before Covid 19. in 2016 I saw a Duplex in Deep (As in "D" Class area) East Oakland that went for $369K and in the middle of last year it went for $500K.
