Oh, we are in the midst of this as I write.... not quite a deceased estate, but my mum has moved into a nursing home, and we need to clear out her house, ready to rent.... its a 4 storey, 6 bedroom beauty, with lots of very nice furniture, and antiques, and jewellry and cash hidden in socks/ drawers/ behind cupboards etc etc. So, every single item needs to be checked thoroughly. Fortunately, my dad did do a lot of tidying and organising before he died. But still there is alot to sort out.
So far, its taken us a year to sort through, and I'd say we are maybe half way!
Some of my family live a fair way away, and all of us work full time and have busy families. Our approach was that firstly, we wrote a list of all the major items, and sent around via email to say which items were top of our list to inherit, to work out if there were any major potential conflicts. We then organised a couple of days where we could all travel to the house to clear out every room into a couple of central locations, and again place our "bids" in for particular items which we wanted. Once that was done, the really hard part started...... what to do with the rest. We have sold some items on ebay, thrown alot away, etc etc. There are still 2 rooms full of knick knacks, and numerous items of furniture.
Basically, what we have left are the valuable items that no-one in the family wants, and the junk items which no one wants. Both are difficult to get rid of. We are looking at auctioneers for the valuable items, and either a garage sale or the bin for the rest.
I can't imagine how we could have done this from a distance, unless we had got removalists to pack everything and put it into storage. But I guess if you were happy to just throw everything away, then you could arrange for a cleaning company to come and do that. Or if you knew someone locally who'd be willing to arrange garage sales, that might work.
My thought is that it is probably easier to take a flight, spend a week or so there and get it all sorted out.... otherwise you'll be like us and it will take forever!
