No, they wouldn't. You have to increase the floor space significantly or bring up the BER by 7 ratings.
With the proposed changes you have the following choices:
1. Re- rent now within the current RPZ rules. Your rent won't increase but it seems that the current rules on no fault evictions will continue for the duration of this lease.
2.Wait until post 1 March 2026 and re-let at market value. Keep in mind that if you are a small landlord (3 properties or less) you will be entering into a fixed term lease with minimal rent increases and minimal rights to evict during its duration. At the end of 6 years, you can evict for sale etc. and increase the rent to MV. If you don't end the lease, a second 6 year term starts on the same basis. Keep in mind you may find a Sinn Fein government with an eviction ban and rent freeze in place at the end of the six years.
3. If you lease post 1 March 2026 and you are a large landlord, the rules are more stringent. You can never evict save for tenant breaches. Otherwise the 6 year rules re. rent increases apply.
Honestly, I think I would sell. I don't think the temporary increase to mv is worth the lack of flexibility or the risk.
