Expired valuation Issue

53North

Long story short:

Mother in nursing home since 2020 and her bungalow requires selling to pay her fees. It's a part ownership 70/30 and was valued at £200k so mums share of the value is £140k. We accepted an offer of £141k in April 2021. Buyer was in a chain and their buyer dropped out, but they got another buyer one week later so all was good.

The process has dragged on for months much to the frustration of both us and the buyers but seems to be the norm when a housing association is in the loop. Finally at the point of contracts signed and waiting to exchange when the housing association solicitors said the valuation had expired in October (didn't even realise valuations had an expiry) and that they would not approve exchange until another valuation has been provided. Thing is, prices have increased by 10-15k in the area and we feel it's unfair to go to the buyers at the eleventh hour asking for more money. But if the valuation comes back as +10-15k we've been told we can't still accept the original offer of £141k.

The estate agent says it's not been anyones fault but I feel it's not unreasonable to have expected one of the sollicitors (ours or housing associations) to have raised the issue of the expiring valuation prior to Oct?

Anyone been in a similiar situation or any advice on how best to proceed?

Cheers
