If you are still of record ownership to the property that has a mortgage upon it that is being paid or not being paid, you need to read the terms and conditions of the mortgage or trust deed securing the loan upon the property in that its terms and conditions set forth what the lender can and cannot do as far as demanding occupancy or posting a notice of abandonment.You need to send the lender a letter advising it of your intent to sell the parcel and keep a copy of it for your records and that for marketing purposes the property is not going to be occupied and that it is not abandoned.Good luck.
