There are quite a few individuals and companies that have attempted these at some scale, and traditional construction beats them out on cost all things considered.

Brokers are more for investors that are looking to scale and obtain various kinds of financing to shop around for.I'd highly recommend looking at the companies website and their reviews.

I use Ferrell-Calhoun, but they are a Southern company with limited availability outside of the South.

You want to buy any new properties in a LLC but also depending on how much you want to scale your real estate biz, you may want to create a holding company LLC and a S-Corp if you get large enough.

Title companies often have standard docs they may make available.

So when you sell the asset, that payoff is in the loan file and title company knows to pay that off and pay you the gravy. 

Yes there will eventually be some but it’s the name of the game and good customer service goes a long way.

The LTR is nice, steady cashola without a lot of customer service issues a STR brings. 

The cost is likely dependent on the level of customization and depth needed. 

Moving forward--have full photo documentation of the damages and estimates to repair, and have the manager tell the tenants if they cannot pay in full or with weekly payments, (scheduled to be paid off in full BEFORE the last month of the lease) the management company will move forward with legal action.
