If it was an amazing piece of property and/or if I offered seller financing with great terms and I marketed it well, it could sell in 1 - 3 months.I'm not sure if we're heading into another 2009, because that was a very extreme downturn, but over the past few years, most people I know have been offering a minimum of 40% of market value for land right, with many of them going even higher.

You can 1031 exchange a portion that makes sense for you (office right now is market specific and an opportunity if you know what you're doing), and take the other portion as "BOOT" and pay taxes on that portion. 

My main thing is in how little people have explained this concept to me.

Do you lend in TN and how much do you allow the seller to finance and how much does the buyer still need as a down payment please? 

It really depends on how quickly you think you can pay back the loan.

For example, how does this deal look if the rehab costs 30% more and takes 6 months?

First of all- how much is this park worth to you?

Appraisers do not like being told how to do their job!

The value I ad How did you find this deal and how did you negotiate it?

I know I need to learn all local regulations, why the property is available, if the current tenants have leases, all of the financial analyses (Let me know if any of you have come across something I might not know), section 8, available grants, and possibilities to finance the deal if the numbers work.
