The lady I spoke with was very motivated because her husband is sick and the house has too much upkeep.

That is the only possibility I could think of as the bank loan would be on the land with the house and the contract with them would be for the remaining land.

So look at it this way, you're going to send 500 letters a month for several months without any real motivated calls.  

What's their motivation?

This motivated seller wanted to sell their 1940's wood frame house that needed EVERYTHING!

Get your motivation from people who actually do it not outsiders. 

Making us go into the detailed settings just to remove someone doesn't promote camaraderie--as I suspect was the initial motivation for making it harder to remove people than it is to add them; it just makes me more apprehensive when I accept new requests because now I know how convoluted it is to try and remove people--and even then, it doesn't work.  

A bad deal will always remain a bad deal. 

Not because your creating motivation with your mail, but because the potential seller may not be interested in selling when you send the first round, but in round 3 their situation may have changed and they are motivated now.

And it needs to make sense the way underwriters think.It's all very deal specific.I write the Motivation Letters for my clients that say exactly what underwriters want to read, and have them "check for accuracy" before signing them.
