I would bet good money that they are paying below market rates.In case you missed it: get rid of them.Spruce the property up, study the market to determine a fair market rate, and find a renter that is willing to pay the market rate, pay the deposit, and abide by your agreement.Not everyone is cut out to be a good landlord.
