Welcome to the site @Joel Jackson!

Prefab is great because it reduces the amount of tradesman out on the site.

There are also usually affordable housing sites that you can post on.

Ok, I'll bite.....give an example of a home that is affordable, sustainable and desired by many.Remember it is critical that you as the business owner (and your partners/investors) make a good profit after paying overhead and operating expenses.

Maybe try a few different description formats across your listing sites and see if a certain type gets you any additional leads?  

Eventually there's going to be a site that's good for owners, probably a flat fee model, free for users and the savings will destroy VRBO and Airbnb.

I've purchased a few owner-occupied properties in Washington, buying houses and fixing them while living in them before moving on to the next.

One of my clients recently purchased a home in Big Bear for STR and I understand it's going pretty well.Best site to check numbers is directly on Airbnb.

We saw an large initial wave of demand when they chose the site. 

Period.The gain/loss and depreciation recapture are on the owner.
