Ugh, no offense to the OP, but can we just get rid of this whole topic? 

Maybe it's best to continue to build up cash so that when there is a correction, you can buy for cash-flow then.I don't want to hijack the OP's thread, so feel free to PM me to continue our conversation. 

But OP I am in a market that varies widely for STR but most places here aren’t restricted....yet.

These are just two random savages who are trying to weasel their way into becoming the OP's tenants.

The OP stated that he was passionate about renewable energy; this is what I was commenting on.A buddy of mine is a mechanical engineer.

I wouldn't pay me 10% to do it.Another thing is the OP doesn't have any experience at this so they are learning on the job.

The short answer to the OP is this.... 

Does anyone have a sample "IRA LLC" operating agreement (or web link to an op agreement) which you would mind sharing?

Anyways, as you can see, there are so many little details and nuance that to make a blanket answer that airbnb arbitrage is good or bad doesn't do the OP any justice as it all depends on the specific deal's details.Oh and to those who say that STR are a lot of work, at least in my experience, buying either a single family house, condo or apartment that isn't more than a million dollars will have a lot of difficulty attracting a GREAT property manager. 

In the case of reinvestment op zone investing is much easier because you do only have to invest profits.
