Well got a quick primarily offer for a mortgage offer after viewing and making an offer which was accepted sent in 3 months of pay slips a p60 2 bank statements utility bills and passport. was well on the way to hopefully getting a firm offer from a lender get and lender came back with a 75% mortgage so we had the other 25 percent. I work offshore so it was good to go or so i thought was off shore for 3 weeks and then asked for terms and conditions of employment which I sent and another 2 weeks pass wanted more payslips 1 day before due to go offshore again, got back more pay slips needed as bank couldn't get their head round how I am paid as get it on a 2 week pay 2/3 weeks pay 2 weeks no pay .this was after me and my wife phoning office on the friday" NO answer to calls or emails" when they said a final decision would be made And now sellers are giving only a week and they asked for another bank statement to check wage slips and deposit!
