Financial investments are inherently risky. It amazes me how people are such huge proponents of upside gains, but find unpalatable the idea of downside risk.
The housing market is terrible at the moment - if you were to kick the tenant out you'd probably still be waiting until this is over before you're guaranteed to get a new tenant anyway. Plus the usual estate agency overheads. I'm slightly too financially conservative/liberal to say landlords are in the wrong to kick tenants out during this crisis, but only slightly. Which is saying something! I'm glad that in the UK we have some government support to help both tenants and landlords.
