I am interested in building rentable SFHs in Houston.

It reminds of the people who go into the casino, and melt down at the table when bust on there last $ and start screaming at the dealer that they "should have" won that hand, gotten so-n-so's card blah-blah-blah....     

I’m exploring emerging areas like San Antonio, Houston, Austin and Dallas.

Think lakefront properties in small towns, destinations with new attractions (casinos, amusement parks)...Another idea is investing in properties suitable for accessory dwelling units to create dual-income setups, especially in cities with relaxed ADU regulations.

Showing a level of expertise to do something hard or exciting certainly piques the interest of a guy with money and no RE experience.We lived in Houston and self managed properties in Oregon and Maine that we snuck away to in the summer.

There's been a few Houston developers on Biggerpockets podcast episodes.One that comes to mind is Donovan Adesoro. 

65%, 70%, 75%, 85%?

I am in the Houston area where I build most of my commercial projects for my construction company.

I live in North Georgia and a few people have said the town in general has declined since the casino was built but I figured that would draw more interest and the numbers still look pretty good.

Just to mention a few:- Wynn Casino (First Casino in the GCC states) in Ras al Khaimah- Al Maktoum International Airport (set to become the worlds busiest airport)- Palm Jebel Ali (the second palm bigger and more luxurious)- Expo City (Regions largest exhibition center)Its a lot of information but I believe it gives a simple explanation to the complex market here.Let me know if you would like to know more about the market and if you would need guidance into exploring the possibilities here!
