5 months is likely to be nothing at the moment...
Our situation: We listed our house for sale in mid Dec so we could start looking at places, thinking we might have some interest over the Xmas break. It sold within hours, which was ace, but meant we had nothing lined up. There was little on the market and were told more should appear in the new year... we waited, relaxing more of our criteria and desirable area, and waited, and eventually found somewhere that nearly ticked all boxes in mid Feb. We made a cheaky offer which was accepted. Mortgage meeting and paid for the survey and then lockdown (before the survey was done)... But, I'm now on furlough and have been told from work to not expect to be back until Aug and it will likely be part time. Now, call me crazy, but I'm not willing to move to a more expensive mortgage until I'm back to work full time and have a feeling of job security again... So, say I return part time in Aug and then full time in Sep (which I honestly think is optimistic) - by which time the mortgage approval has run out, so we need to reapply. For that I'll need a payslip (showing full pay), so that will be end of Sep, meaning mortgage meeting in early/mid Oct. Plus some time to get an idea of job security, so we're only going to be in a position to move in Nov (at the earliest)...
To make matters more complicated, we've just received the survey results (apparently the survey was done before lockdown, but nobody has been around to type it up until last week), and the survey is shocking enough we've pulled out of the purchase. So, now we need to find somewhere else (potentially with less commuter-centric bias with a likelihood of prolonged working from home) - so if we find somewhere with a decent upward chain, it could be well into next year...
I've chatted this through with our estate agent who understood and agreed when I explained it all, and apparently our buyers are happy to wait (for now) as there's nothing else on the market they're interested in. So, they've effectively got min 11 month wait from offer to exchange, and their buyers were apparently 3 months earlier, so 14 month wait for them...
When you think about the gated requirements for each stage, like some gantt chart, it's soon clear that anyone in furlough will need to wait to return to full time work, then a month for a payslip (or potentially 4 months to get 3 payslips) to get mortgage approved, which could mean the end of the year for a lot of us. So, in the present climate, 5 months is v unlikely - hell, our present house's purchase was over 5 months (with slow solicitors and the length of the chain) and that was 5 years ago without a pandemic...
