Hi,
First of all, a great post and a very pertinent question.
The only problem is, that a lender will not give you a loan for the purpose of stamp duty.
so you have 2 options:
1. Get a creditcard and use the cheques they give you to pay the stamp - normally at a high APR so not great, but if your parents are going o give you the money, it will be for a short period and you can pay it off asap.
3. Look to get a loan for something else that the lender wil accept e.g. car, debt consolidation etc. This would free up the necessary cash to pay the stamp.
Personally I'd go for option A.
As for the kidney sale, I believe that bottom of the market has dropped out for 2nd kedneys :-)
