We put my late parents house on the market at a very realistic price, taking into account it had never been updated. We had lots if viewings, one of whom offered a very low price saying it needed work...well, yes, that’s why it was the price it was!
We took it off the market for a month then put it back on at a higher price. Someone else came along and offered a lower price, which was actually the price we’d originally asked. Result!
If you’re not desperate for the money from the sale, and are still waiting for probate, then I’d just wait and see what happens, three weeks is no time at all.
