Rent affordability is slightly better outside Northern Ireland, at 29 per cent of household income.
“Positively for both tenants and landlords, this year we’ve seen stability in UK rental price growth, with increases remaining broadly in line with the rate of consumer inflation,” said Martin Totty, chief executive at HomeLet.
“For landlords, there remains a sustained demand for property, with the private rental sector continuing to provide the market with both flexible and long term housing options.
“Private residential landlords will continue to play a key role in the wider UK housing market. Whilst the outlook for property investors remains positive, one of the key concerns for the market in 2019 would be a potential lack of supply in certain regions.
“The government’s squeeze on private landlords via taxation changes and more regulation could discourage their continued participation in this important sector. Unlike the trends we saw in 2018, any reduction in supply could lead to rental increases that are above the rate of consumer inflation.”
