I have a house in Washington that has developed a septic issue.

I don't know about multifamily, but for sf rentals it a good market, rents are growing, population is growing, lots of new development, but prices are still lower in redeveloping neighborhoods  than other parts of dfw.  

It was a huge practice space for musicians and it was bought up by a developer and he did the VERY uncool thing of booting every artist out of it. 

The housing development of condo type in my city has been increasing in the last few years.

But if i am looking a property for a housing track they will give me for free a developers package which is a huge 3 ring binder with all sorts of data  from demographics utlities zoning and if I request a full title search.. this all for free.. with the expectation if i buy that development they are going to get 10 to 50 million in title policies.. from my retail buyers.  

Quick questions to those that know Bergen Lafayette / Greenville Jersey City real estate and developments well.

What I don't like is it's hard to identify optimal investment pockets.Dayton, OHPrice to rent seems lower than Kansas City.

Is it based on the rent or cost of property or density or the developments in that neighborhood? 

I am first narrowing down on a few States, then get to counties, then to cities and then to neighborhoods - leaning a lot toward the SouthOnce I have narrowed down a few cities/neighborhoods, I will look for realtor agents in that area primarily through BiggerPocketsIdea is to identify a killer agent with whom there is a connection.  

@Jonathan Klemm Im tryning to use it as a strategy to identify an appreciating markets.
