@Elan Adler,
Thanks for the story of your experience. Over the long hold I would expect that you will find a good appreciation. When I talk with investors about the build to rent opportunities in the sunbelt we talk about finding areas of growth like you have found. Nation wide we are still a long way behind on numbers of homes needed. When you find a good market that shows steady growth, you get in the way of obvious appreciation.
I would agree that the Cap Ex numbers for new construction are far lower than other homes. most of the investors that I work with are planning on moving the investment before most of that Cap Ex would be needed.
This type of investment works well for the investor that is not looking for another job. As others have said, no REI is totally passive, if you find the right group with all venders in place, the investors that I work with find it can be a pleasant transaction.
Best of luck with the investment
