Ultimately, supply needs to exceed demand for their to be any meaningful reduction in short term house prices.
I think people unaffected by death, divorce and debt will be reluctant to move and do any major financial transactions in a recessionary environment. So I would imagine demand will be low.
Death and debt may cause supply, if the debt rate continues to grow exponentially and if there is mass unemployment/salary reductions in the middle sectors, but these are unknowns at this stage. So I agree with posters who say that if there is a marked impact on house prices, it will come sometime in 2021.
I think what may potentially impact house prices even more, is the change of behaviours and requirements of house buying. People may look to buy bigger more expensive places to accommodate working from home, they may also want to be around nature more. Who knows...
I don't think there will be mass movement of people out of cities, as people will need these social hubs even more so, given social distancing creates more 'isolated' home lives and people may want to be close to established social networks and general buzz.
I noticed a lot during lockdown, that many people with gardens were still going to parks etc, as they craved seeing other people and just the general buzz of life around them. I don't think that will change.
