As a landlord who rents my house out 20% below the market rate I'm going read up on this with I Teresa. Foes the freeze occur at the market rate or what rent you currently set?
Depending on how long the freeze lasts for I can't see this working out if say your rent no longer covers your expenses.
I only rent out the one house and in turn rent in very very expensive part of the world that I can't offord to live in ( for work). I'm waiting to see if the new epc ratings become compulsory because I can't get my house above a D without solar panels or a heat pump.
Quite a few landlords will sell up over the next few years, presumably the gap will be filled by large companies or overseas landlords. Maybe that is the best, who knows, we shall see.
My bottom line is the house staying self sufficient and when is doesn't I'm out. So meh, but if it means I need to up my rent to near market value to protect it from a long term freeze below market value as it is now, that's not going to benefit anyone. I doubt my tennants can offord a rise right now. More to read up on.
What I don't like is these clangers being dropped out of the blue, like no evictions during covid ( didn't effect us) but increasingly its not what I signed up to 18 years ago. Long tennacy but overall if they left I would run screaming for the hills to get out of being a landlord. The only way I can do that right now is to evict. I'm too soft for that.
