We live in a neighborhood that has 6 lots remaining that the builder hasn't mowed all year. They promise to do them, but never do. I've encouraged the board of our HOA to give the builder 72 hours to get them mowed and remove the debris. If they don't, we do it and bill them for it. If they don't want to pay, we put a lien on the empty lots. I was thinking of offering to do them for $40/lot(They're all about 1/3 of an acre on average). Do you think something like that would stand up if we went that route?
