Rented!

So I'm pretty stoked I've found tenants for my house. I couldn't really afford to go on maternity leave and have my house sit vacant. A family of five will be moving in next month, after I move out of here and into the construction zone that is soon to be Our House. I didn't meet all five family members - the couple brought their youngest, an eight-year-old, along to see the place. The girl was polite and talkative and made eye contact with me, which I believe reflects well on her parents. Is it wrong to judge potential tenants by their offspring? I was hoping for a retired couple or maybe a smaller family (five people are really going to wreck havoc on my water pump), but I got good vibes from the kid.
