Vendor has second property to sell - how long to wait?

ca0v123

So our vendor has a second property to sell, due to moving in with family for medical conditions - this is their grandparents house. They’ve found a property that is end of the chain due to a divorce and those sellers are renting rather than buying. 

Both the property we are buying and the other one they are selling have been up since end of November, we had our offer accepted a month ago. How long is it acceptable to wait for them to sell the additional house? We are First Time buyers so it’s a close ended chain essentially but we just cannot proceed until this sale goes through. I appreciate it is past their control and we will wait but obviously it’s quite an anxious time.

thanks

I would continue looking until they are in a position to proceed.
