I'm also pondering whether rental will be hit badly during the crisis.

What I think:

Unemployment increase, might cause rental demand to go down as job seekers may not need to rent a place for work.

Tourism hit badly, units doing Airbnb/Homestay will be vacant, thus more unit supply in the market, making rental rate more competitive.

Covid19 make ppl stay home more, so demand for rental will increase?

Ppl reluctant to commit to illiquid asset like property, thus prefer to rent more than stay, increasing rental demand?

Ppl might downgrade during the crisis, thus bigger units might be affected?
