I like miami and columbus because miami is land locked and the opposite. columbus is very affordable. both are the highest net migration cities by head count in their respective states 

Now my only risk is time if I don't like it and have to migrate.

Another argument might be that you can never tell when a neighborhood is going to crash in its property values, or when people will migrate to a nearby one that is flourishing.

I guess we would see more migration to the south and midwest.

Appreciation is never a guarantee so you follow migration and development trends to hedge your bets.

It was at that time, we began our migration out of MF to self storage. 

It's not a migration to the town from Charlotte as suggested, although statewide growth has been consistent, Kings Mountain is a bit far from the economic gravitational pull of the Charlotte metro area, and the out-pacing in pricing is due to the casino, not so much a shelter from higher prices in Charlotte. 

Per this NY Times article, the average American knows around 600 people.https://www.nytimes.com/2013/02/19/science/the-average-american-knows-how-many-people.html#:~:text=The%20average%20American%20knows%20about,do%20you%20know%20named%20Kevin%3FPer the US Census Bureau, the average American moves 11.7 time in their life, which based upon an approximate lifespan of 84 years, works out to be about every 7 years.https://www.census.gov/topics/population/migration/guidance/calculating-migration-expectancy.html#:~:text=Using%202007%20ACS%20data%2C%20it,one%20move%20per%20single%20yearSo, if the average American knows 600 people and they each move about every 7 years, that means that the average American knows around 85 people that move in any given year.How many of those moves do you want to be involved in?

I moved to columbus and so did thousands of other people for the opportunity and the economic development. look at the net migration patterns. that's what drives development, economies, etc. if you have some data to back up your investment thesis I'm all ears. but my focus is on Central Ohio new construction economy.

Your calculations are spot on  I just had a bid on a Hud  property which turned out to be a unusual email from Chronos  The home was under contract and the buyer left the water on or there was a leak and caused about $10,000 in damage (according to Hud) They migrated some of the damage pressured tested the water and it was back on market I bid a net of $171,000 or so to net (list price was $195) and received an email from Chronos that the minimum acceptable bid was $171, 321   i was able to up my bid to the acceptable amount and now have it under contract This was the first time Chronos  directly intervened in a bid The only bad thing is I am only allowed to activate the electricity and not the water and gas Also cash is an option on the contract and they treat hard money as cash   Electronic signatures are also acceptable goodbye blue ink
