Connecticut- the thing is - there is no security deposit left, based on the damages done already. We not talking wear and tear, but broken window by kids playing ball in house, holes made in wall, etc. I can inform her what the interest would be (if there was security left)but I have no intention of paying her interest now before she move. She just needs to pay her late fees now and start paying rent on time. The suggestion to have three months record to show cronic lateness sound fair. If there is any other ideas, please help me.
