I'm in the lower income market, the majority of the population in the Valley.  

Population is very low but there are many city's within 5 miles. ( yes I did mean 5 miles ) seems crazy but its true.

@Sean Dawson there are a number of reasons why people who theoretically could buy a house wouldn't, and they are a large and growing part of the population of homeowning aged people in the US.Let's start with the 7.3M who lost their home between 2007 and 2014 (and counting, by some estimates to 9M+ before it's all over).

Population is largely low income.

(you could say it was luck BUT I was new in this area an was only willing invest  in counties/town where the census data was showing a stable population gains, past and future)   Noways I have about  $1000 true cash flow for each, including reserves,  dept service etc.......It is called creating wealth from thin air!

Most folks using these methods need to use these methods, that is the majority of the population.

The property is in Pascagoula, MS, which is a little Gulf Coast beach town where around 10% of the population is stationed at the Naval Base there.The gross rental income is a bit over $38K, which is what initially really caught my eye! 

However, in North Carolina MHPs are very good long-term hold assets provided the right  market attributes - a growing population, stable employment and a restrictive land use code (high entry barrier for new MHPs). 

Would you purchase a flat land that is 806,295 sqft that needs to be re-developed in a population of 45,000 next town over is populated at 85,000?

Too bad we don't have a resource that provides a macro economic comparison or ranking by zip code on such things as house sale turn-over, prices, trends, job growth, population growth and inventory levels for things like lots, new homes, etc.
