Very topical thread!
We have just withdrawn our offer on a property as the vendors point blank refuse to consider renting and have only just made an offer on a property where the sellers haven't even found anywhere yet, so we have no idea what the resulting chain/timescale might be.
We are cash buyers with the funds literally sitting in the bank.
Our offer was accepted in February. Full survey done and we have incurred costs for a builders visit to estimate for (not insignificant) work identified by the survey, plus our legal fees.
We are moving back to the UK from elsewhere and need to confirm dates with international removers who get booked up months in advance.
We now need to make a short notice dash to the UK to find another property and it is looking highly likely that we will end up putting all of our belongings in storage so as not to lose the removal slot.
If you want to sell your house then, realistically, there comes a point when you actually have to leave the property!
