I think there's still a lot of room in the country to do this successfully and where the locals can also benefit.

While it's easy for everyone to post success stories, it's way more difficult to post personal negative stories on an online forum, so thank you for having the courage to do so for our benefit!

Within the last 2 months, I've been approached by numerous investors asking if I do rent by room which I currently do not.

It will familiarize you with the basic terminology and benefits.

There are benefits to having a second LLC over the first. 

Your not getting any STR properties via arbitrage your just managing someone else's property and the owner is getting most of the benefit. 

@Otis Clayton You say "I am at the point that I want a partner with some cash and credit to refi the deals I get from marketing and talking to sellers"Based on that you are looking for someone who has cash and credit, wants to invest/benefit from real estate but does not have time to find deals.Look for someone like that, be clear on their role and your role.

One way to get tax benefits while you're living there could be installing solar panels or upgrading the energy efficiency of the home. 

But, I have used this strategy numerous times when time was much more important than money to a seller.

So how do I socialize the benefit of doing something like taking a 200k ADU construction loan to add $X in top line and $Y after servicing the new note, but with an increased property value etc etc?
