I'm in line with the thinking around the population trends and the migration towards Southern states in particular.  

It clearly shows to where business are starting and to where they are migrating.

@John Woodrich we do have a positive migration

It was caused by a collapsed chimney flue allowing the water from the furnace condensation to collect in the chimney, which migrated to the walls.

Even that may result in a reoccurrence as fleas can probably migrate that short distance or possibly find a way through the walls.

All three had positive net migration numbers (Houston had negative net migration because of the hurricane/flooding in 2017).Lastly, a lot are saying that Houston markets are already over saturated with investors,  the property prices are too high,  etc.Since I am trying to narrow my market search in investing in a 2-4 unit property would you guys agree that I should eliminate the Houston markets above and focus on Norman OK, Winter Garden Fl, and Boerne TX?

I am in south Florida and do most of my work in Miami-Dade, Broward and Palm Beach County and the macroeconomics and job growth accompanied with massive in migration from millennial's is continuing to excite me.

Here's an article I wrote here on the site that will help bring you up to speed on what's happening in the market. https://www.biggerpockets.com/forums/621/topics/396725-millennial-migration-to-sacramento-2017---here-comes-the-rushLet us know if you have any specific questions and we'll try to get you pointed in the right direction!

And therefore, housing expenses go up – whether it’s rent or purchase price.It’s simple supply and demand.If you’ve read some of my other posts here about millennial migration and the trends affecting the Sacramento and Stockton housing market, you’ll understand why there has been a sudden increase in demand for Central Valley housing as of late:https://www.biggerpockets.com/forums/621/topics/396725-millennial-migration-to-sacramento-2017---here-comes-the-rushhttps://www.biggerpockets.com/forums/627/topics/528157-stockton-the-last-bastion-of-housing-affordability-in-californiaThis trend isn’t stopping either… more and more millennials are turning 30 every year (over 4 million) and the average age a woman has her first child is 28.

Before I start this discussion, I wanted to post the link to the Article with the title "Population migration patterns: US cities Americans are abandoning" but don't go to the link YET.
