I am certainly not the right person Brendan I agree, By the way when I said the tennants I meant owners, I am only offering advice as a friend , The girl asking for advice is dealing with an estate agent, Solicitor and an engineer. The engineer did find problems with the drains and my friend got a quote from him as to the cost of rectifying this, It is not substantial but her solicitor is advising her to sort it out herself after the sale as it might put off the vendor, I would understand it if she was paying a bargain basement price but she is paying the full asking price, Her solicitor will contact the estate agent today to see if the vendor is willing to sort the problem but was told this would be unlikely, The only advice I offered her as of now was to ask her solicitor to contact the estate agent and see how the vendor views the situation given that my friend is the only potential buyer, and she is willing to pay the full asking.
