there seems to be some confusion here.
at least on my end
Estate sale / estate auction
in my brain I see an "estate Sale" as indoor/outdoor yard,garage,house contents walk around everything has a price sale.
and of course "estate auction", on site, or at an auction house Auction.
am I wrong about what you mean in your areas, by the word sale ?
You are correct Jeff. True estate auctions are usually on site versus at an auction house. Estate sale is an "entire contents" sale with everything priced by the estate sale company.
The bad thing with Estate sale companies versus family run sales are-
1- the prices, usually way too high and many times it's cheaper to purchase the same item on Ebay for less.
Family members will sometimes price a few things they found on Ebay but not usually.
2- They clean out the house. By that I mean all the drawers have been gone through, the beds cleaned out from underneath, the closets searched etc. etc. This lessens the opportunity to find any "hidden treasures". Most of the time family members haven't cleaned out anything. They may have removed a few choice items that they wanted and removed personal keepsakes such as photo albums and such, but even that isn't the case all the time.
3- Because they've cleaned out the house, they've disposed of anything they deemed worthless, which in many instances i'm sure they have thrown out stuff that isn't worthless, especially when it comes to ephemera and related items. As above, family members many times haven't done a thing except open the doors up for you.
4-Because they've cleaned out the house they've already found the really "good stuff" and because they are in the biz. then the possibility is greater that they have researched or already know the market value of most items "found". Family members usually don't care they just want to get rid of stuff, it's less they have to clear out or clean up.
As for estate auctions, the value of the items depends on who is there bidding on it that day. I think some of the bigger companies probably use phone and internet bidding also. Correct me if i'm wrong but, for the most part the only bidders are the ones on site, especially with the small local outfits, at least the few that i've been to. This gives great opportunities for really good deals to be had. That's the whole reasoning behind going to auctions.
That's some of the differences. Estate sale companies are the worse. I have no problem paying a decent price for something. But as bazinga has stated, if I wanted to pay retail, i'd sit home on Ebay and look for stuff.
