Even if the home was incredible with a great rehab its still going to be in a low quality area which will still attract low quality tenants giving you a statistically overall bad experience.

Every neighborhood will have a median income - statistically speaking.

Very interesting statistics and I like your thought provoking questions.

Statistically nationwide crashes are non existent.

Investors of seller-financed loans (aka real estate paper) now have measurable statistics on industry trends and sophisticated financing models.

I've been told to look at trends such as the City's GDP (Gross Domestic Product), MSA (Metropolitan Statistical Area), and HAI (Housing Affordability Index).My question is where do you all tend to look for these metrics and are there any other key market indicators that you prefer to take into account? 

Learn your market-study the schools, the neighborhoods, the crime statistics, which price range house is the selling fastest.

What demographics and statistics do you look at before investing in a market?

The other side is in excellent condition and rented to a long term tenant who pays $1,350.00  We are thinking about this as  BRRR but are concerned about the probable lack appreciation, about the crime statistics, about not owning anything else in this town and the  high taxes.
