Since I'm taking such a cash hit, I asked the sellers agent if they would be able to designate some portion of the sale price ($200k?)

How many Due on Sale clauses have you actually seen enforced?

Kyle,Before you do this call your lender or who ever is serviing the mortgage and find out if they allow a transition into an LLC or if they have a "Due on Sale Clause". 

You can find comparable sales in 2017 and use that dollar/acre figure to arrive at the fair market value then. 

You'll need to get good at figuring out what each property needs on each deal.  

Since they can't do each property individually, they use comparable sales to make broad generalizations to determine percent changes.

It means that you, as the purchaser, cannot close on the purchase of the property until (subject to the terms of the contract) the seller identifies a new asset to acquire with the proceeds of the sale. 

Quote from @Keilon Morton: I am looking to secure my first tax sale and need another investor to go in on the deal.

From an email I received from FF:New year, new rental goals! There’s never been a better time to step into the booming mid-term rental market. Since you’ve shown interest in listing your property with Furnished Finder...

Purchase price: $187,000 Cash invested: $15,000 Sale price: $259,000 I got tired of moving place to place and worrying about finding roommate, security deposits and not having enough money to deal with maintaining someone elses home.
