We are currently starting to do flips to fund our STR acquisitions, are people typically buying properties through wholesale or using a realtor?

You can always ask for a copy of the SS Card along with ID and Pay stub.Yeah, they have to verify you because you are requesting other peoples information.

I'd either rent a window unit AC or buy a roll-around indoor unit from Lowes/Home Depot.

. $1,180,000 to THEM (this is the $1,425,000 DUE on the WRAP AROUND Note - MINUS the $245K due on the 1st lien payoff -leaving $1,180,000 to them) Q- Who would buy such a Note ? 

The people involved have a particular amount of assets(equity) and no or negative monthly cash flow. 

Can you hold on to anything you buy for 2 years before reselling? 

How would I advertise the spaceI was also considering buying a few tiny homes and placing them on the empty portions of the lot.

When I had my property management company (and the people I sold it to and manage my properties continued it) the policy was late fees are split 50/50, which I think is the ideal scenario.My rational was it takes more time and effort as a PM to collect when a person isn't paying, and at the same time the owners might not receive the rent when they should, so 50/50 compensated us both. 

Buy it, fix it up, and build up equity to reposition into a bigger asset.With the profit from the house hack, you do have certain tax exemption.
