There is a house in the better neighborhood I buy in that has blue carpet.  

The lines are not very sharp and one can argue about the cutoffs but thats the way I look at it.Another way is to think about who would live in that neighborhoodA: Doctors, Lawyers, ExecutivesB: Nurses, salespeople, other white collarC: Truck Drivers, Retail Workers, Construction, other Blue CollarD: Welfare/Section 8/Drug dealers.

It's got people from Lee's Summit, Blue Springs, and independence. 

So is it normal for a house to be non active and received offers "significantly' higher out of the blue.

Judges in that area like to make up new rules out of the blue sometimes. 

My take on this is that if I buy rentals in blue collar neighborhoods I am more likely to face these issues on a regular basis, and if I was going to do a lot of business in that area I would consider hiring a part time bi-lingual employee and train him/her to perform property management duties, which we all know are not just limited to screening and signing leases; I want to maintain good communication with my tenants to make sure the property is well maintained.

If you can borrow at under 1% buying blue chip property at 5 or 6% is very smart cash flow investing.

From what I've gathered so far, the #1 factor to look at when evaluating a market is jobs.The chart above shows the total number of jobs available (Green) and the total number of people employed (Blue) in Fresno CA.You can see there's a definite uptrend since the recession (Grey).

Just curious is it even worth the money to pick up seemingly affordable trailers on 1/4 acres or to fix up for rental properties.Seems like the most common type of blue collar housing here.I know a little already regarding metal roofing, newer being easier to finance, etc.Does anyone else buy these?

I circled the areas in blue that are higher priced neighborhoods.
