You cant be doing this without a lawyer
and this is something you need to ask yourlawyer
yes increased fee, however the upshot is that bydoing it badly you maybe giving them security of tenure
The real issue is that you are signing for a property with vacant possession, ermwhen it is not, in fact you have sitting tenants
Bad News, youwant to get a lawyer in on this at the beginning rather than sortinng it out in a year or two
Use the phrase sitting tenants to your lawyer who is handling the transaction and see the look on his face !
