An unusual situation, something I haven't dealt with before and would be interested to see what people think. I've discovered that my tenants are out of the country for a month and have left their two teenagers (15-17) behind. I found out because the neighbours called me about house parties and anti-social behaviour going on up there. Naturally the kids have loads of friends staying over and are living it up with the parents away. This isn't your average rental property, it's a really high-end house and am very particular about who I rent to as really don't want it to get wrecked. The tenancy has gone really smoothly up to now (4 years) with no issues, they've been ideal tenants and I've been very good to them as well, negotiating a rent way below market rates, but this has shocked me. I wouldn't give kids the run of the place for the weekend never mind a month and am worried about what might be going on up there. From what I've heard already from the neighbours the friends staying over are a rough crowd. Am I being unreasonable? I've already been in touch with the tenant and they don't see the problem as they say their kids are really responsible. Thoughts?
