Landlords in Ballymena (BT42, BT43 and BT44) usually come to us with a council letter, a fire risk assessment or a house they have just bought. We price from whichever you have.

- A licence is needed where 3 or more people forming more than two households live as their main home and pay rent; the NI HMO Unit at Belfast City Council licenses for every council.
- Space and amenity standards come from the HMO (Living Accommodation Standard) Regulations (NI) 2019 and the licence conditions.
