I'm thankful that USPS never was able to get their hands on sending/receiving emails (remember?)

You are going to spend a bunch of time wringing your hands about an LLC and not about the property itself

And how many properties did you have, when you decided to handed to a property management company?

I'm assuming this is the one you're referring to but there also are a couple traditional RV Parks here with a handful of full time or at least long term traditional tiny houses on trailers.

I’m just asking for my own selfish motivation / inspiration and to dial in a buy and hold strategy.

This means your holding costs and your funds for vacancy have to be accounted for.

I haven't discussed with the seller one-on-one as to why they would hold the note, although I understand the benefits of why one might.

Investment Info:Small multi-family (2-4 units) buy & hold investment.

So essentially you will need money for ten percent of the purchase price, the first portion of the rehab, and holding costs to pay the hard money payments monthly and taxes/insurance. 

Managing an STR a very hands-on 24/7 job if properly managed with a decent occupancy rate.
