We have a piece of rental property. We have a management firm that books it and subsequently takes care any incidental issues that come up. Major things they let us know so that we can arrange/approve of before they fix anything. Changing batteries in smoke detectors, replacing light bulbs, weed wacking are minor and they take care of them without asking. We only live an hour away from this property but this is what they do - and they charge us for it. I can't imagine that the real estate agency doesn't have this kind of service in place to cope with properties whose owners are no longer close to the property. Just simple things like monitoring the air/heat systems, mowing the lawn, weed control, bushes trimmed, etc. all seem to be things that a REA should have in place already for this home and perhaps should have been part of the original contract/arrangement. They're acting like this is the first time they've had a property where the sellers have moved out. Did they perhaps want you to sign on for such a maintainance service and you declined so that is why they're letting you know about such a minor issue as batteries?
