I moved out of an apartment at the end of July that my husband had lived in for 5 years. We told them to keep the security deposit of $425 as the carpet was very heavily stained(and had been before we moved in). On september 11th they called and left a message asking for an additional $800 or they would sue for $2500 the full amount of repairs. My husband called back and left a message on the 12th saying that he would pay $400 in october. We did not hear from them again until they called today and left a message asking for $400 this week. They never sent us a list of charges and they did not contact us until over a month after we moved out, but my husband already agreed to pay. The repares were for new carpet and paint. Are these considered normal where replacemnts? What are we required to pay?
