The short answer
Do not throw anything away, do not donate anything, do not sell anything, do not let anyone take anything, and do not price anything until a company has walked through the house. Those five sentences cover most of what follows. They sound extreme, and families push back on them for an understandable reason: a full house is overwhelming, doing something feels better than doing nothing, and it seems obvious that the pile of old magazines in the garage is trash. But an estate sale company earns its commission by finding value in an ordinary house, and it cannot find what is already gone.
None of the mistakes below comes from carelessness. They come from good intentions, grief, and a house that needs to be empty by a date. Knowing them ahead of time is most of the protection you need. The companion to this guide, how to prepare a house for an estate sale, covers what you should do in the same weeks.
1. Do not throw anything away
The first instinct in a full house is a dumpster, and it is the most expensive instinct there is. What looks like junk to a family sells at an estate sale in a way that surprises nearly everyone the first time: half-used cleaning supplies, old tools, tangled costume jewelry, boxes of buttons and sewing notions, cables, holiday decorations, canning jars, garden pots, vintage magazines, worn linens, the contents of the junk drawer. Buyers who come for the small things fill their bags from tables of exactly this, and a company will lot it, price it and sell it in a weekend.
The bigger risk is what is mixed in with it. Cash, jewelry, savings bonds, coins and papers are found in coat pockets, books, shoe boxes, freezers and the backs of frames in a great many houses, hidden by someone who then forgot or never told anyone. A dumpster does not check. Our guide to hidden value in an ordinary house lists the places worth a look, and the honest rule is that if you have not looked, you should not throw it out.
If something genuinely has to go before the company arrives — spoiled food, a broken appliance leaking on the floor — fine. For everything else, wait. A company would far rather clear what does not sell after the sale than learn the family filled a dumpster the week before.
2. Do not donate or give things away early
Donating feels like the kind, responsible version of throwing away, and it has the same effect on the sale. Charity pickups take furniture, books, kitchenware and clothing — which is to say, a good part of what would have been sold. The family gets a receipt for a value it estimated itself, and the estate loses the sale price. There is a place for donation, and it is after the sale, when the company has sold what it could and what is left is what nobody bought. The guide on donating unsold items and getting a receipt explains how that works, and estate sale versus donation compares the two honestly for a small estate.
The same goes for giving things to neighbors, friends, the caregiver or the church. Each gift is generous and each one is also a decision about the estate's property, which, if you are an executor, is not entirely yours to make. Rules on what an executor may give away vary by state and this is not legal advice, but as a practical matter the safest course is to sell first and be generous with what remains, or with the proceeds.
3. Do not let family pick through the house without a plan
Every company has a version of this story. The family is quoted on a full house at the walk-through. By the time setup starts, the dining set, the silver, the good jewelry, the tools and the grandfather clock have gone to various relatives, and what remains is the ordinary furniture and the kitchen. The company's estimate was built on the pieces that are now missing, the advertising it planned has nothing to headline, and the buyers who spend the most have no reason to come.
Family members are entitled to keep things, and a good sale still leaves room for that. What goes wrong is the way it happens: first come, first served, with a truck, before anyone has agreed what is being kept and what the estate needs to raise. The fix is to decide together, before the walk-through if you can and certainly before setup, and to remove what is being kept in one go. Our guides on what to keep from a family home and dividing personal property among siblings are written for that conversation, and handling family disagreements over an estate sale is for when it does not go smoothly.
Tell the company before the walk-through, not after
If the family is keeping the best pieces, say so before a company quotes. A company that prices its work on a house that then shrinks by half may raise its rate, add a minimum, or decline the job, and none of that is unreasonable. Being told up front is what lets it quote honestly.
4. Do not sell the best pieces yourself first
A related mistake, and often a more expensive one. A dealer who knocks on the door, a neighbor who has always admired the desk, an online listing for the jewelry, a buyout offer for the whole garage: each of these puts quick money in your hand for exactly the things the sale would have led with. Quick offers on the best pieces are almost always low, because the person making them knows something you may not about what they are worth, and because you are being paid for speed. The estate buyout versus estate sale guide goes into when an outright offer does and does not make sense.
It also removes the sale's advertising. A company photographs the sterling, the mid-century furniture, the coin collection and the workshop full of tools, and those photographs are what pull serious buyers across town on a Saturday morning. Those buyers then also buy the ordinary things. Take the headline items out and the whole sale draws less.
If you suspect a piece is worth a great deal, the answer is not to sell it quickly; it is to find out. The guide on how to find out if something is valuable gives a research method anyone can follow, and a good company will tell you when something belongs at a specialist auction rather than on a table in the living room.
5, 6 and 7. Do not price, clean out, or stage the house
Do not price anything. A company prices from experience of what its buyers pay in your area, and that experience is most of what the commission buys. A family's stickers are reliably wrong in both directions: too high on the furniture, which the family remembers being bought, and too low on the things nobody recognized, which is where the money often is. Every sticker then has to be removed. If you want to understand how the pricing will actually be done, the guide on appraisal versus estate sale pricing explains why an insurance value and a sale price are different numbers and why that is not a mistake.
Do not clean out closets, drawers or the garage. A company sorts every drawer itself, because that is where the small valuable things are. Boxing things up to be helpful means the company has to unpack them again, and something packed in a sealed box is something that does not get priced. Clear a path, deal with any smell or pests, make sure a bathroom works, and stop there.
Do not stage. A house that has been tidied so that the rooms look nice is a house in which a buyer cannot see what is for sale. Companies stage in their own way: tables in every room, things brought up from the basement and out of the attic, the closets opened, the kitchen laid out by category. Leave the walls, the shelves and the furniture where they are. The one exception is safety: a loose stair, a hazard on a walkway or a rug that slides should be fixed before anyone walks through.
One call saves a great deal
Before you rent a dumpster, book a charity pickup or spend a weekend emptying the garage, phone the company you are talking to. Every company has its own preferences about what it wants left untouched, and the answer takes them a sentence.
8 and 9. Do not leave the wrong things behind, or the house unsecured
The opposite mistake is just as common: leaving things in the house that should never be sold, and then being surprised on Saturday. Personal papers — bank statements, tax returns, anything with an account number — are found in every desk and most closets, and a company will put aside what it recognizes, but it is not there to read every envelope. Photographs, letters and keepsakes end up in a box of frames priced at two dollars each. Prescription medicines should go back to a pharmacy take-back program, not into a bathroom lot. Phones, computers and drives hold a lifetime of data and should be wiped or removed. Firearms are subject to rules that vary by state, most companies will not sell them, and they should be secured and discussed with the company and, if needed, an attorney. The guide on documents, photos and personal papers covers the paperwork in detail.
Do not leave the house unsecured during the weeks before, either. A house known to be empty, with a death notice in the paper naming the address, attracts attention. Change or account for the keys, keep the small valuables locked away, and be careful how widely the address and dates are shared before the listing goes up. A company will usually publish the street address only shortly before the sale for the same reason.
10. Do not rush the contract, or the date
Grief and a closing date make people sign quickly. The first company to return the call gets the job, the contract is skimmed, and the sale is set for the earliest weekend the company can manage. Each of those is a mistake with a cost attached. Get two or three companies to walk through and quote, because rates, minimums and what happens to the unsold items vary far more than families expect — the guide on getting estate sale quotes shows how to compare them fairly. Read the contract with the contract checklist beside you, particularly the clauses on unsold items, the payout timing and cancellation. And look for the warning signs before you sign, not after.
On the date: a full house usually needs a company one to three weeks of setup, and a sale that is advertised for a week draws better than one announced on Thursday for Friday. If the house has to be empty quickly, say so at the walk-through and let the company tell you what is possible. Sometimes the honest answer is that a clean-out with a few pieces sold separately serves the estate better than a rushed sale, and it is better to hear that from a company than to discover it at settlement. The week-by-week timeline shows what a realistic schedule looks like.
What to do instead
Secure the papers, the keepsakes and the small valuables. Decide together what the family is keeping and remove it in one go. Fix anything unsafe and leave everything else exactly where it is. Then get a company through the door before you do anything irreversible. You can describe the estate once and local estate sale companies will reach out to you, free, or browse companies near you first. The guide to preparing a house for an estate sale is the other half of this one, and the complete estate sale checklist keeps the whole process in order.
Frequently asked questions
Should I clean out the house before the estate sale company comes?
No. Clear a walking path, deal with any smell, pests or leaks, and make sure a bathroom works, but leave the closets, drawers, garage and basement alone. The company sorts every drawer itself, and what a family clears out as junk is often what would have sold. If something must go, ask the company first.
Can family members take items before an estate sale?
Yes, but decide together what is being kept and remove it before the company quotes, or at the latest before setup begins. Pieces taken after the walk-through change what the company priced its work on, and the best pieces are usually what the sale would have been advertised around. Whoever is executor should also check what they are permitted to give away; rules vary by state and this is not legal advice.
Should I sell valuable items separately before an estate sale?
Usually not. Quick offers from dealers and neighbors on the best pieces tend to be low, and removing those pieces takes away what the company would have used to draw buyers. If you suspect something is genuinely valuable, research it first and ask the company whether it belongs in the sale or at a specialist auction. A good company will say so.
Should I price items myself before an estate sale?
No. Pricing from local experience is most of what an estate sale company is paid for, and family pricing tends to be too high on furniture and too low on the things nobody recognized. Every sticker then has to be removed. If you are running the sale yourself rather than hiring a company, that is a different question, and our do-it-yourself guide covers how to price.
Is it bad to donate things before an estate sale?
It costs the estate money, because a charity pickup takes furniture, books, kitchenware and clothing that would otherwise have been sold. Donate after the sale instead, when the company has sold what it could, and get a receipt for what is left. That way the estate is paid for what had a buyer and still supports the charity with the rest.
