And then, , with the trend back towards insourcing, meaning manufacture of goods in the United States based on what happened with the supply chain and China, , investing in areas along major interstates is probably a good idea to the transportation and logistics is going to be very, , very strong there.

We are in the Seattle market, so reality is that demand so significantly outweighs supply that on new construction you aren't really at risk of not selling, its more for at what price per sq ft it will end up selling for.But one mechanism build in is that there is a $100k buffer where he will hold at least $50k of his build fee until after house is sold.

I have been in talks with a GC in Georgia and his method of building is: He builds everything at costs and doesn't include any markup or fees, he oversees everything, I only supply funding, and we split 50/50 the profits after paying back the bank and all other associated fees.Since I am only supplying the funding for the deal, is there a way I can structure doing this so that this is considered passive income for myself since I won't be involved with the construction or overseeing the project?

I'd tell them you will buy it and install it, however, their rent will be increased $X a month to cover the fact that you've now supplied a washer and dryer. 

The question is how is the profile of the state in regards to landlords, growth for the economy, supply of land, and is this house attractive enough on the exit to garner an aggressive bid if you were to sell in the next up market cycle in 7, 12, 15, 21 or whatever years?

Real estate is a complex asset class due to the lengthy process of increasing supply.

Our response stressed that we take great care of the pool with weekly maintenance, that they enjoyed having the temperature in the high 90s, and we are glad they liked all of our pool and beach supplies, etc.  

I always wonder because the more people say an area is great to invest in, it seems it will drive up supply of houses.

Utilities, taxes (property, local vacation, & income), landscaping, furnishing / decorations / amenities, pest control, & supplies (soap, TP, etc) are the big ones on my STR calculator that you didn't mention.I'd also recommend using the enemy method to determine expected income.

As long as there is a good thesis as to why the demand will remain high for shorter stay rentals  and most importantly (1) the use is allowed, (2) the use requirements are protected by in place permitting and licensing and (3) the permissions are transferable through a sale you will be on the right side of the supply/ demand equation.
