HAP - the perfect recession-proof income?

Full time LL here.
As so many people are now measuring the potential effects on their income over the coming months, I’ve realised that the only rental I consider to be a risk is the one that is a family with traditional income jobs.
All other rentals are in some form of government rental assistance programme (Fas, HAP, permanent disability).

I’ve been surmising if HAP the ultimate hedge against income drops in a recession ... it’ll arrive every month, as long as the tenant pays their quite small contributions. I have excellent tenants and excellent relationships with them, yet at the moment I’m feeling far more secure in the HAP ones.

(I don’t mean rental price drops btw, when the gov may drop their contributions in line with market falls, that’s just the ebb and flow of the market).
