Deeds and transfer taxes in a sub2 deal

[Markeilsha R.]

I have two questions about doing a sub2 deal. When writing the contract and the seller is just selling for the price of the existing mortgage an delinquent taxes, how does that get reflected in the contract for the transfer taxes? Basically if the mortgage and taxes come up to 75k and that's all they want, is there an actual cost since the owner isn't getting any money in their pocket? How would I phrase that? In this case would it be better to do a quit claim deed or a special warranty deed? I tried to get advice from a local title company, but they only do simple translations.
