What would you do?

Hello Not sure if this is the correct place to ask but this is my current situation

This will be my 3rd/4th time selling and buying a house.

Fortunately I have a large amount of equity in my house to use as a deposit on next house

I have now sold but cannot find a place that is our forever home.

My buyers are now moving very quickly and getting abit pushy

I do not want to loose the sale

I can ( will be a pain ) but move into a family members home and a place to store our belongings for free.

Have a AIP and mortgage offer will not be a problem ( have advisor )

My question is should I carry on with sale and hold back as much as possible until we do find a place and risk potentially loosing sale or move out and wait till something comes up?

Houses in my area seem to be either dropping or just not selling at the price so agents are dropping them. Is it a risk??

Anyone had this situation?
