There is very little benefit to being worth 100 million as compared to 5 million if you have normal desires. in life. 

Personally, I would sign the termination and move on.When you do owner financing, you are typically selling to someone that can't qualify through a normal lender.

We go through the normal purchase and sale process over about 50 days. 

The issue being is it’s a little above my normal price range and a little outside my normal investing area.

It's about an hour from where I would normally invest but a deal is a deal.

If by chance you're just trying to do a normal refi then you don't need to wait 6 months unless you want to.

You should be able to take any normal business expenses associated with RE including section 179 and normal depreciation.

If you think pure mathematically, the amount of tenants out there who are going to stay 5+ years and move during "normal" months is always going to be drastically lower than the folks who move ever 1-2 years and all months of the year. 

Does this seem like normal procedure?

Things (in general) are less likely to fall apart if agents are involved, assuming this is a normal owner occupied deal.
