I certainly would.Furthermore, in this particular situation, is the seller aware of the AFR, which is an acceptable federal rate? 

I accept Direct Bookings by the way, and some are sourced from sites like Furnished Finder. 

Just a heads up that I've never had luck getting an owner financing deal accepted through a realtor, as most agents don't understand seller financing.

The signed lease is sufficient as a legally binding contract, confirming their acceptance of the new rent amount.

Yep, that's the risk that you accept unfortunately - lack of liquidity and control.

Hello,I am trying to find out whether or not Fannie/Freddie accept K1's from MLP's in my stock portfolio account. 

You don't know how the process works so I don't know why you think you would be getting offers accepted without a pre-approval or proof of funds.You get a pre-approval with a lender you know and every time you make an offer, you just have them adjust and confirm the date and the new property address.

Perhaps you could provide the ESA documentation to the insurance company and have them provide in writing to accept or decline the insurance. 

I've mentioned a few times where Cozy has an issue in that they don't permit you to choose which payment types you will accept. 

The 2 year lockout period means that they will not accept additional payments beyond the minimum payment (trade-off is that sometimes you can get them to go for interest only).
