This also has the effect of slowly improving your tenant pool by adding people with more disposable income. 

Keep in mind you will have cleaning fees in your expense column, but those should also be included in your income column in addition to your nightly rate. 

The interest charge is negligible 4.75 and it is tax deductible, for a net effect of 3.5% (assuming 33% tax).  

I'm curious to know if anyone has had luck with virtually staging their properties.  The thought is that the potential buyer can walk through the property with the listing pulled up on their phone and have an example ...

You don't need to worry too much about that.Benefits of assigning: You get your fee and walk away, Super easy and clean for youBenefits of double close: Your investor will never know what you are actually making on the deal

So it's like someone slipped and fell on your property after a snowstorm and it's "you mean you  didn't get someone to clean up the snow?" 

In my case it would have effectively been impossible to assert that the loss property was NOT QBI eligible, and yet the others are?

That does not mean you just simply pay less, it will have effect on your entire investment (longer commutes to check on things, lets buyers / renters, more days on market, lower rents, lower appreciation, etc).You will still need about 30-50k in cash to make this happen (20-25% down, repairs, closing cost and other expenses so keep that in mind.You also said "cashflow from day 1".

The biggest mistakes I have made were when I assumed I was strong enough to overcome the psychological effects of dealing with debt. 

It's going to take a lot of cleaning, plus the windows and such that you mentioned.
