What is your plan in terms of housing when the house is being renovated? Did you get the renovation professionally costed? As noted above, the cost changed between posts. Can the house be lived in without the renovation as an 80k renovation is quite substantial? Is part of this renovation a nice to have or is everything needed in the short term. I think that while downsizing is perhaps the best option, the way you have been tackling it is somewhat irrational. You created difficulties for yourself in the long run going into arrear with 70k savings, you have put your house for sell and are also sale agreed without having an agreement and a clear plan on how to get the money needed. The amounts you need to borrowed varied from 147 to now less than 100. If I was the buyer or the seller involved, I would run away fairly promptly.
