My accountant has always told me it's next to impossible to qualify for any type of 'active' management of your property. 

The reverse is almost impossible.

I've tried finding the market cap rate and it's impossible because we have so few sales in any given year.I bought an 11-plex (closed last week) and the best comparable the appraiser could find was a motel that sold three years ago.

Since I've been told that it's very difficult/impossible to find 6%+ cap properties in A Class, how about B/B+ Class?

That said, nothing is impossible but I did want to point out the difficulties you would face looking for that.

If you are funding a purchase and the purchase price is market price, then it is going to be impossible to resell the house at a profit.     

If you're interested in single-family homes, then it will be practically impossible to find anything in the greater Austin area, including Cedar Park and Round Rock, that meets the 1% rule.

For some potential homebuyers, acquiring property financing to purchase a home can be difficult or impossible in the near term.

Just like where you are: I'd imagine it would be really tough to find something that cash-flows in Hayward but it would be absolutely impossible in Woodside or Atherton.  

Do know that in NYC and NJ its tough as costs and competition are high, its not impossible but you need to have a good plan and solid team in place.
