I like 3/2 brick or block houses (so I don’t have to paint) and are in the sunbelt (Specifically TX and FL markets with growing populations over 100k) because I don’t want pipes freezing, since we started investing while we were overseas.  

However, if you're really looking to grow that money, this isn't something I would recommend as it's not expected that these lots have a ton of upside in the near future.

The city is developing quite fast and prices keep growing year after year.

And building my portfolio and growing it as time goes by. 

Also they're not looking just to make money, well some of them are, but MOST are looking for a second home for their families and children to grow up with the same summer and holiday experiences they had as a child. 

The growing list of issues include multiple poor quality tenants damaging properties and breaking leases with no recourse, and non-existent communication/accountability from property management to the point where I have zero faith in their personnel correcting the issues I'm experiencing. 

I've noticed a trend: the OG's that went through the GFC 2008-2010 meltdown are fine with a low return on equity and cash on cash return, avoiding mortgages and paying with cash, while the Young Bucks are all about maximizing leverage, $0 down strategies, creative financing, "infinite returns", growing the portfolio to the moon as quickly as possible and measuring it by number of doors as the primary metric instead of equity/ actual wealth. 

Granted that is a Business, but it was still preferable for us and the seller.Get in with low payments then as you stabilize and grow the payments do to but you aren't scrambling in the beginning making high pressured decisions. 

Columbus' mixed economy and growing numbers make multifamily properties good.

I'd like to start building a portfolio in more of a nascent market that has more room to grow in coming years.Perhaps Santa Fe still has some room to grow, as you suggest?
