Thinking that you can sell your house one day and move into the new house you buy the next is a mistake in this climate, in my opinion. It will cause you untold stress. You would be very very lucky for both these events to coincide perfectly.
The sale of your own house may fall through, the purchase of your new house may fall through - due to reasons only emerging a few weeks into the sale processes.
I think you should plan an interim stage where you are renting or moving in with relatives for a while before you buy your new house. You are now being rushed into buying a place at the full asking price when you haven't even sold your own house yet.
Maybe you have the savings to buy the new place outright and it is not dependent on selling the old house, in that case it's different.
