Has anyone had to clean out a parent's hoarder house and property?

I had to do the very same thing all by myself about five years ago; my Mom had Alzheimer's, and I had no idea how bad the hoarding situation had gotten. It's a monumental, emotional drain. I spent three weeks straight inside that house, sleeping on the floor, and worked straight through for three weeks to go through her four bedroom, three bathroom house (with a full garage, basement, and porch stacked up about five feet high in every direction). I came up with a game plan for the house, and knew my goal was to rent it out by XYZ date, so that was a great incentive to get it cleaned up. Please message me back if you would like an outline of how I organized the clean-up. Basically, you need to decide on how many piles or subsets you will need, and designate certain areas of the house for each sorting area. Charity, Auction, Storage, Trash, Take to Mom, and Shred were my sorting sets. Please message me if you would like the details; I don't want to bore anyone with the layout or planning stages. You will need six or seven large tarps (different colored tarps work best).

rent a dumpster,, use it. That is what I did.

Is 1-800-gotjunk an option?

I don't know if this is an option for you but we sold my hoarder uncle's place as is, the house was a tear down anyway.
