subject to

[Lee S.]

I've not seen the answer to this question and i'm hoping someone can help.  I understand subject to and roughly how to handle a deal like that.  What I don't understand is how to handle a subject to deal where the price agreed upon does not match what is owed on the loans you are taking subject to?

Example, (these are made up numbers):  House worth 200k, current loan on house is 80k and I have an agreement with seller for 115k.  They are willing to do subject to on the 80k.  What options are there to deal with the other 35k?  Do you make a note?  Cash?
