Taking care of Estate business

My sister and I with much support from our husbands have been spending almost every weekend cleaning up the parents' home and property for the estate yard sale.  Their home sold As-Is due to some very bad building decisions regarding the add-on sunroom's roof slope.  That area of the house leaks severely and the parents were too sick to care much and my brother who lived with them and was their primarily caretaker really didn't have the time or knowledge to fix it.  So now the area has mold and would not pass any FHA or traditional loan inspection.  Thank goodness that we were given a blessing from a buyer who purchased the property as it was for cash.  There is only one condition to the sale: all trash is to be removed.  And that is the nightmare my sister and I are currently trying to deal with.  The parents were married 50 years and never, ever threw anything away.  My brother lived with them for about 12 years and also never, ever threw anything away.  It is a mess trying to clean and sort and decide what is trash and what may have resale value.  My brother-in-law found a very large rattlesnake skin in the tractor shed.  Needless to say where I am not going any longer.  We were given another blessing from a family business associate who took all the canning jars, including the ones filled in 1998 and are still full.  In return my sister and I have one less thing to empty and clean.  I will be creating and posting an e-book on what I have learned about the probate process in Alabama.  I hope to upload it to either Amazon or i-Tunes.  I found the resources available to deal with this process lacking.  No one should have to pay a lawyer to know this information.
