Land Contract on a future short sale

[Josh Nabors]

I have a question concerning a land contract/ subject to deal.

I will be proceeding with one of these deals, however, I have a question. She is "selling" the house to me for 75k but currently owes 98k. Essentially, I am land contracting a short sale. Whenever I buy the property in the next 2 years,  will I own it free and clear even if she owes the difference still?

What sort of things should I be on the look out for?
