There is no single official figure for the average rent increase in Louth: increases vary by property, tenancy and whether the rent is being reset for a new tenancy. The RTB Rent Index can show how rents in Louth compare over time, while the applicable rent-control rules determine what may be charged in an existing tenancy. Your landlord must follow the relevant statutory cap, timing requirements and notice rules, which can depend on when the tenancy began and whether an exemption applies. Check the latest guidance and rent calculator on the RTB or gov.ie websites, and consider professional advice if you believe an increase is unlawful.
