During this time, they will negotiate pay off amount in exchange they will send a letter to the credit company stating that you have pay off the loan.  

Put it on a letter and send it to them. 

Make a digital package and some paper copies to bring with you.

I'm not saying there aren't a few of those types of deals, even in my farm areas, but there just aren't a lot of people stupid enough to sell those properties below market, particularly not when there are realtors putting letters on their front doors every week. 

But when you get a love letter from the AG then it gets serious  :)

Where can I find a 'Letter of Intent' to take control of a property I'm interested in wholesaling?

If they are due a surplus, they are probably already getting at least a dozen letters so you would have to really stand out. 

I wrote a letter outlining who our company was and what we wanted to do with the property.

You first deliver to them a Letter of Intent, usually a non-binding document stating your intention to purchase the property for a certain price, type of financing and other criteria specific to this deal.You want to have the actual income and expenses to analyze before you make an offer.  

My last call was from a property owner that is ready to sell a property because she can't visit the property as often as she'd like.She told me that I am the only one out of all the letters she's received that called her back or even answered the phone.
