We have had a good offer in to let our house but it is from three boys (!) aged 19-20 who are at Imperial College in London. They want to take the house for three years (not until I hav seen how they get on for a while for sure) and I just wondered if anyone has some good questions or points that I could raise ahead of time. I am not thrilled at having three boys who have just left home but need to get it rented out as am paying two mortgages currently. Any ideas pleasssssssssse.
