'AITA to be concerned about my in-laws renting out 2 rooms of their house, to 4 strangers, and then leaving the country?'

"AITA to be concerned about my in-laws renting out 2 rooms of their house, to 4 strangers, and then leaving the country?"

So, my in-laws recently finished extending and renovating their house, and it’s now a 4 bedroom house they are happy with. They always talked about renting out a room to make more money.

However, I learned yesterday that they plan to rent one room out to a family of 3 (mum, dad and 9 year old), and then one room to a postgrad student. However, the in-laws are also planning on flying out to their native country for a couple of months (FIL is flying out on New Year’s Day, MIL will follow a week or two after).

My brother-in-law will be there, but he’s not particularly engaged or knowledgable (34 and always lived at home -he lives in the 4th bedroom).

I think this is a risky decision. These people are strangers (supposedly they’ll be credit checked by SpareRoom or something) but they’ll be broadly unsupervised from after a couple of weeks in. And leaving aside security concerns, I’m wondering what happens if the tenants have an issue with the house, considering it’s newly renovated.

I raised this with my wife (in private) to see if she was also concerned, she got mad at me, and said I was being judgemental. Is it just me who thinks what they’re doing is a bit risky?
