Savills suggested raising it to 614k.
Anyone know the chances of getting more than 4X your salary as a single person on 71K
Yes, it's possible. I think this is called an exception, and in my experience some lenders give exceptions more easy than others. I think they have an amount of exceptions that they can do or willing to do per year. One lender told me that if I was asking for an exception to the 4x, to make sure to not ask for say 4.01x, it's better to ask for 4.1x, 4.2x, etc. assuming that you can afford that.
