There was a huge reaction to RTÉ's investigative documentary about renting in Ireland

Some of the content of the documentary was quite shocking.

Nightmare to Let, an RTÉ Investigates documentary six months in the making, promised to deliver some shocking home truths about the rental market in Ireland and grim though some of those truths were, it certainly lived up to that promise on Thursday night.

Amongst some of the discoveries in the programme was that Dublin Fire Brigade was forced to close three multiple occupancy buildings with over 120 tenants between them, including one building with over 60 tenants.

A fire safety expert described the conditions in another building as "the worst he had ever seen".

Furthermore, it was also revealed that only 4% of rental properties were inspected last year and of those that were inspected, more than two-thirds were not compliant with the regulations.

If that wasn’t bad enough, there was a 100% failure rate in four districts – Kilkenny, Louth, Offaly, Limerick city and county.

Tenants, meanwhile, described having to share two toilets between 24 people and another spoke of staying in the “horriblest place I've ever been”.

From a landlord’s point of view, meanwhile, the programme documented the case of one landlord potentially making over €26,000 in gross income a month from four properties with 108 tenants.

Not surprisingly, given the extent of the revelations, there was a massive reaction to the documentary on social media on Thursday night; if you didn’t catch it, you can watch Nightmare to Let on the RTÉ Player.
