I see this all the time lately. The blue lockboxes are Supra boxes. They cost about $75 each.
The vendor box and the front blue box belong to the current lister of the home.
We do our homes this way, too, with a Supra box for Realtors, appraisers and inspectors and a vendor box for any tradesmen we send into the house — and also to have a spare key on the property. For reasons that seem obvious to us, we don’t put the two lockboxes in the same place.
The blue box in back belongs to the last listing agent, for whom the home didn’t sell.
I’d have to run the lockbox to know for sure, but when I see more than one blue box on a property, my assumption is that the previous agent has left the business. Otherwise, why leave a $75 asset hanging on the hose bib?
We’ve thought about offering $20 for the release codes for these orphaned lockboxes: A little dough for you, and we’ll pick up the lockbox.
A sad story, but it’s not the liquidator’s job to weep over the mess, but simply to clean it up.
