Genuinely not sure which way to go on this one - we've noticed on many occasions now that the french doors on the first floor balcony of the property we let are open (not just unlocked - wide open) during the day every time we pass, when neither of the tenants cars are parked outside (there is a drive with 2 spaces). On one occasion, I had to stop by to collect something from outside of the house, it appeared that nether tenant was in, but the doors were wide open again. Its a small house so pretty evident to me if someone is in or not. Its quite a through-route and friends and family often comment they've noticed the same when passing.
They're otherwise very good tenants and until now I've just thought, well its none of our business really, its an unfurnished let and if they get burgled its their problem. Not only that, if anything its reducing the risk of condensation and mould (always one to look for the positives, me). We recently performed an inspection and are very happy with their standard of maintenance etc.
We've gone backwards and forwards between ourselves over this, it could be that we are mistaken and they actually are in, their cars may be parked elsewhere, one of them might have taken a night shift job and sold a car etc etc. Its on my mind today as I'm renewing their contracts and come across the clause that includes a clause about their duty to secure the property when absent from it.
I know most people will probably say have a polite word to them about it, but they have made it very clear they like to to be left well alone unless absolutely necessary, as they have every entitlement to be as tenants.
WWYD?
