Also remember that Fort Worth and to a lesser extent McKinney are very diverse cities.

- The market: How diverse is the local employment? 

Things I'm looking for:Population growth, diverse industries/job base (all the usual stuff that indicates long term growth)I'm debating between single and multifamily but I'd love to find a market that has small multifamily properties in A or B (maybe C+) neighborhoods (some places I've looked at only have these in D class areas)Cash flow but also some appreciation, can be moderate for both I'm not looking for anything crazyA less expensive market than San Diego (the cost of entry here is nuts)Things I want to avoid:Markets that are all cash flow and no appreciationMarkets with very low average income and very low property values like MemphisTexas because I'm concerned about the power gridAnywhere that's prone to hurricanes or flooding, especially areas that are newly prone to hurricanes & flooding due to climate changeAnywhere with a disproportionate amount of violent crime.

I would also look at diversity of industry.  

West Philadelphia is diverse and changing.

The population has been growing here year over year over the last decade, it is home to The Ohio State University which has over 50,000 students that live here along with those that visit, and it also holds a diverse range of young professionals and traveling nurses to fill the demand of the multiple business corporations and hospitals stationed here.

Ohio is a great market for real estate investing because it has a strong and diverse economy, favorable tax incentives, affordable housing, and a strong rental market.

@Tunde OsilajaSome folks have already mentioned this, but Chicagoland is a very diverse market, where you can find anything from an A-D class property and high to low returns.

There are thousands of hows, that’s what’s so great about RE you can have a totally diverse portfolio under this one umbrella
