The age profile of individual landlords is getting older while the number of companies involved in the rental market is increasing.

Meanwhile, rent as a proportion of income is highest for tenants in Dublin and 71% of tenants nationwide are in employment.

These are amongst the findings in a report today on the rental sector from the Central Statistics Office.

The report includes data from several sources and is part of the CSO's so-called "Frontier Series" of publications.

Today's report paints a picture where small landlords still dominate the rental sector but where change is underway.

Between 2017 and 2021, the proportion of individual landlords under the age of 45 fell from 35% to just over 24% as private landlords left the business and fewer entered it.

By contrast, the number of rental properties owned by companies and pension funds has gone up from just under 20,000 in 2019 to just under 30,000 in 2020.

For 44% of landlords, their primary source of income was paid employment with Health and Social Work the top job type followed by Finance and Real Estate activities.

The mid-point gross rental income of landlords was €13,800 in 2017, rising to €15,352 in 2019.

However, 50.5% of landlords had net rental income, which is after expenses are deducted, of less than €10,000. 79.1% had net rental income of less than €20,000.

The rent burden, which is the percentage of disposable income spent on rent, was highest for tenants in Dublin. 40.4% of tenants in Dublin's North Inner City spent over 35% of their disposable income on rent in 2019, the CSO said.

Tenants over the age of 65 are in the age cohort which spend the greatest proportion of their incomes on rents. Almost half, or 49.4% of the over-65's spend more than 35% of their income on rent.

Today's report also noted that 36% of tenants had gross income of less than €20,000 a year.

It also found that 45% of rental properties were built between 2001 and 2010. Just over 38% of rental properties were apartments in 2021.

The report also has extensive information on the BER or energy ratings of rental properties. It finds properties owned by companies or approved housing bodies have over three times the proportion of A or B rated homes, at 32%, compared to individual landlords at 9.8%.

The CSO does point out, however, that of the 385,583 rental properties identified through the Residential Tenancies Board database, only 40.5% could be matched with a BER certificate and 66.8% could be matched to property registered for the Local Property Tax.
