I understand that as a leftist myself the ownership of many buildings sounds capitalist and I should not support that, however in this situation the trouble is with the system and not with the people that own the buildings.
I think in the UK you have to prove you have sufficient liquidity to pay off a loan and maintain it or you have to get loans that don't surpass 20% of general annual income (this could be completely wrong though). Landlords that have been here a while will not have much to worry about if they were preparing for a crash to pick up new properties, some have threefold in certain growing regions here in value so a lot of liquidity could probably still be found even if the rate halves or something.
Saw a news article today asying a lot of real estate has started to stagnate due to covid 19 and it'll cause more problems over the next year or so immediately for definite...
A lot of people will struggle to do viewings and get listings and if people want to stay in a house to see how it feels are you going to have a 2 week period between people so no one catches anything how's that going to work?
A lot of people will say you can do virtual viewings but who trusts estate agents not to "touch up" photos or hide creatin things... Painting the day before a dry spell and then pretending there is no damp/mould is possible if you can't smell it or anything...
