Unless you are buying super cheap homes for under 100k each, or are purchasing homes in areas with consistently declining population, you will likely not hit these 'rules'.The median home in the US is valued at 231k according to zillow. 

The population of the city has grown consistently for the last 10 years, it's relatively close to where I live, and I am think it has the potential to be a great rental market.

Look at the population increase estimates on Charlotte, PHX, Huntsville, ect...

I would recommend Columbus because of our job and population growth.

@Alexander ParadaHouston as a market is a good one, Texas in general has one of the lowest unemployment rates and highest population growths in the country.

There is a long list of categories that you can look up from the population count and age statistics, Housing stats including median home values, rental and vacancy rates, crime rates and lots more.

All others populate from the MLS through IDX, which can be hours or days later. 

Educated work force, high employment growth, income growth and population growth.

My towns population is only 9500, so my strategy will probably not work in NYC.Look at your competition. 

Like to meet like minded investors to share ideas/strategy on potential markets using population and job growth data.
