We don't live in the urban jungle and live in very safe area's of the metro areaOak Park, Warren, Eastpointe, Roseville, Redford, Livonia, Lincoln Park, Dearborn Heights, Farmington Hills, Clawson, Southfield, Southgate, Trenton, Wyandotte and on and on and on.Detroit has lost half of its population. 

Adding in a population stability, I was set with that area. taxes are high and cash flow is more difficult than some other areas away from major cities, but cash flow is not impossible.

Some businesses, not so in RE really, may generate x dollars quickly and level off and remain constant, an example might be taxi service where demand can be met rather quickly, business levels will remain rather constant in a community du to population and where regulatory constraints may limit the number of vehicles in service, rates charged and limitations to competition.

It isn't enormous, but has a large enough population base and is an economic center for the area.I have a friend who does very well in north canton, not to be confused with canton proper.

Now were left with a majority local born population for the first time in decades.

Both have extremely strong job markets (I would argue some of the most stable and strongest in the nation) and both have population growth.

In order to pursue this I am looking for cities with growing populations over 10k, with an average age below 40, stable long term employers and an average household income of under $50k.

@David T.In our market we have about 45% or so of our population that rents so we dont really see a shortage of renters in our market. 

On top of a heavily blue collar population in whole.

I personally manage 100 units of similar apartments in the city of West Palm Beach, FL which has 100k population vs 20k in Gardner.
