The property she lives at was last sold in 2018. Not sure if she mentioned how long she lived there but it’s not social housing. The house was about €110,000 so quite cheap (by most housing standards in the UK and Ireland anyway!)
(Also, for the benefit of someone who wanted to verify who I am: OW20-9)
I've looked up the address on the residential tenancies board directory and it's on there as a 3 bed house (every house that's rented in Ireland has to be on that list).
So her house is a rental property. As far as I can find on Google, Air BnB/ short term holiday lettings do not come under the remit of the residential tenancies board so it wouldn't be on the list for that. It also doesn't cover rent-a-room schemes (where the landlord and tenant cohabitate in the same property).
You also have to renew your listing every year so it's unlikely she used to rent it out and just doesn't anymore.
I can't say I'm 100% sure on this but it does seem like from that info that she's the tenant of the house while also advertising it on Air BnB etc.
Also, did anyone else see the Reddit comment from someone saying they used to work with her in Domino's in Ireland? Interesting stuff.
