You should not pay 70k for ~$650 in rent ($850 - HOA).I don't personally like anything with HOAs because I don't have control over when they are raised and each time they are cuts into your monthly cash flow and (double whammy) puts downward pressure on the asset value.The HOA doesn't cover any insurance? 

If you can get a job first that will allow you to lock down that first house hack to cut out your housing expenses that will likely be a good way to go.

So that was a waste of time since we only signed a few leases - 4 I think - 30-60 days each.

I wouldn’t waste my money.

But I would like to start smart and limit wastes of time.

This is exactly why I have all my sellers force buyers to do inspections right in the beginning - because it really sucks to go all the way through the approval process and have the buyer walk away after over a condition issue that could have been found and negotiated earlier, and now its just too late and everyone involved wasted months of their time for nothing.

And your broker may or may not be okay with being cut out of the deal.Can it be done, but complicated.

Ouch, that cuts. 

A multi-single member LLC in Wyoming seems a very odd choice unless you mean a Series, but that will still get each Child Series (as with all Series) subject to the $800 minimum a year Franchise Tax.The only irrevocable trust would be one for your Primary & secondary residence - but then it is expensive to break that, you have to figure out your life expectancy to anticipate the trust ending before the end of your life to get any tax advantages and the QPRT no longer has the incredible tax advantages it used to (though it might in 2026 when/if it reverts back to the old structure) since the sweeping changes of the Tax Cuts and Jobs Act (TCJA) in 2017. 

I would take out ALL metal plumbing and update waste pipe to PVC and supply to pex.HERE, we have a lot of rust, calcium deposits, and lime, besides grit ruining faucets etc.
