An idea.,  2.  

I think it's good advice to check for proper SEC registration. 

Any ideas of next steps would be greatly appreciated.

HI John, Investing in Columbus Real Estate is a great idea.

Also, if you are intending to flip it and even hold it for over 1 year, its still a flip.Knowing that, you can only 1031 investment property which it looks like you understand.I have no idea what hainvg LLC's has to do with qualifying for anything on your post.i wouldn't let the "tax consequences" drive your business decision. 

I'm not sure that 'one per quarter' is realistically achievable (or even a good idea?)

We’ve done a lot of improvements and renovations to it in the last year and half and this year plan to use a HELOC to purchase our first BRRRR.We’ve always known the rental market here is strong due to the military presence, but had no idea of the improvements happening around the Murchison area.

That's all to say, I don't think it's a good idea. 

any ideas / advice will be greatly appreciated.

I have turned to a few private lenders some have considered the idea but the fact that they don't do business in Puerto Rico hinges my efforts.
