I can't comment about the sale price question but I do know from personal experance that most solicitors appear to want to do nothing to upset the lenders. Maybe, just maybe, this is because the lenders are involved in property purchasing that forms a significant element of the solicitors income. If they upset the lenders then that lender can make life very difficult for them; "Don't bite the hand that feeds you?"(posted 8190 days ago)I've had various solictors tell me I don't have a case, or else they have dragged their feet for months doing nothing but charging me fees.
When I located a solicitor who did no property purchasing work at all I was able to obtain quality advice about my situation. Advice that has proved to be correct.
Good luck.
