Happened to DD1 and sil even 10 years ago. They had an offer accepted on a house just outside London, in Surrey. Then the owners begged them to wait for a few months, as they didn't want to move the kids mid-term- and DD1 and sil agreed to help them out as they understood re kids changing schools mid-term and had to continue renting until Christmas. Sellers then got in touch and said they were still agreed to seel, but wanted 20% more as the market had gone up significantly in the 3 months they had had to wait to help them out.
They told them to ?!?!? if you get my gist. My they then missed out on lots of houses for exactly the reasons you state- as they both worked and Estate Agents expected them to be available to view houses at the drop of a hat... which neither of them could do.
