Tyler,Within my 20 years of experience as a landlord, if I had $150k and good credit, I’d focus on either flips for fast capital or rentals for long-term cash flow—trying both at once can slow you down.

Name detection is via loan signatures.

If you close with a conventional loan, it will need to be in your personal name.

Quote from @Samuel Coronado: Huntsville long term will get a better % ROI than Atlanta.

Is the mid term rental business that you have a 'rental arbitrage' business?

Since the original loan was apparently for a primary residence an LLC could never qualify because it isn't a person who would owner occupy the property. 2.

Once you do this conversion you can't change it back to a traditional long-term rental. 

It does come down to DTI and what you can show versus what you can qualify for in terms of home price.

Is this structure standard, though, in terms of capping investor returns at 12%?  

Doing so will seperate your investments from your personal assets and protect you from liability. also, one thing you may not know is that you cannot get a conventional loan with an LLC.
