Now if you are seasoned and portfolio is mature and you are not as concern about maximizing income then I can see a migration to SFH might suit someone.  

And now you have Democratic cities such as San Francisco, Chicago, Los Angeles allowing rampant migration, crime and retail theft to continue which affects everything from business to every day life. 

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?

That means any outgoing migration is fully offset plus a lot of people. 

It’s now estimated that Texas has 31.29 million residents, up from the 2020 count of 29.15 million.But Texas also ranked as the top state in the nation for domestic migration and natural increases over the past year.

Plus, I'm migrating to real estate from being a full-time Software engineering Contractor, so I have the aptitude for building a contracting business.To protect myself, I plan to operate my new real estate contracting business as a business, and not under my personal name.

My “reasoning” is based on two points1- the current system of property records filing in a million different jurisdictions with expensive title searches necessary for almost every title transfer and mistakes still being made can be made much less expensive, much faster, and much more reliable through migration to some sort of “blockchain” National registry.2- Numerous investments have been divided into, and offered as tranches of the whole.  

The supply and demand are pretty balanced.Most of our growth over the past 5 years is from in-migration from more expensive states.

My wife and I are leaving California(my last duty station...fulfilled my contract and now a Veteran) and going to migrate to San Antonio.

For one, and this is just my personal opinion based upon all my DD...I'd get into markets where the job growth is substantial as is the migration, purchase 'B' class properties so your ability to raise the rent at a minimum 3.5% national average is achieved annually and many other factors I'd suggest as well, but the biggest would be to look elsewhere other than Memphis, etc.As for getting to 1,000 units within 20 year's it's very possible!
