After the seller fee, an Equipter sold at auction typically nets you several percent less than the winning bid, and the money arrives weeks after you decide to sell. The buyer premium widens the gap further, because bidders count it in their budget. Below is the fee-by-fee math, using the published terms of auction houses that sell Equipter RB4000s and a real 2025 sale.
SLC Rentals is an Equipter-only shop that buys RB4000s outright, so yes, we have a stake in this. The fees below are the auction houses’ own published terms, and we’ll also tell you when an auction really is the better call.
What does it cost to sell an Equipter at auction?
Auction costs come in three layers, and only the first shows up on your settlement statement:
- Seller fees. The auction house deducts its fees before it pays you. Purple Wave’s standard seller agreement, for example, charges a $100 listing fee per lot plus a seller fee percentage that is set per agreement. Get the percentage in writing before you consign.
- The buyer premium. Buyers pay a premium on top of the winning bid, and bidders set their bids with that cost in mind. Premiums vary a lot by house: Purple Wave’s standard agreement sets a 10% buyer premium on the winning bid, while PA Auction Center in East Earl, PA charges 10% capped at $500 per item, plus 2% for online bidders. On a $23,650 unit, that is roughly $2,365 at Purple Wave versus $500 to about $970 at PA Auction Center. You don’t pay this premium, but it is money the buyer spends that never reaches you.
- Logistics and waiting. You haul the unit to the sale (or it is picked up where it sits, depending on the house), wait for the sale date, and then wait for settlement. Purple Wave’s standard agreement pays sellers within 15 business days of the auction or of receiving your title documents, whichever is later. Most lots sell “as is, where is.”
What do RB4000s actually sell for at auction?
Used RB4000s go through auction regularly. Public auction records show:
- A 2019 RB4000 sold for $23,650 on Purple Wave (Wichita, KS) on December 31, 2025, the clearest public sold price we have found. It was an insurance-recovery unit sold with no reserve, listed with vandalism damage, a missing key, possible ignition problems, and no hours reading. Even so, the buyer paid about $26,000 including the buyer premium.
- PA Auction Center (East Earl, PA) and Bright Star Auctions (Middlebury, IN) consigned at least ten RB4000s between them from August 2024 to September 2025, including a 2024 unit with just 25 hours.
- In those records, listings cluster from late summer through December and again in May, when contractors rotate fleets.

The math, side by side
Use that $23,650 Purple Wave sale to see how the fees stack up. Because it was a damaged unit, treat it as a fee illustration, not a price benchmark: a clean, running 2019 should bring more. The seller fee percentage is negotiated, so the table shows 5% and 10% as examples:
| Auction | Selling to SLC | |
|---|---|---|
| What the buyer paid | $26,015 ($23,650 winning bid + $2,365 buyer premium) | No buyer premium: our offer goes to you |
| Seller fees | $100 listing fee + seller fee (5% = $1,183; 10% = $2,365) | No commissions or listing fees |
| Transport | Depends on the house; often your haul, your cost | Pickup included in your offer |
| Time to money | Next sale date, then up to 15 business days for settlement | Typically about a week from first photos to payment; most sellers are paid by wire within 48 hours of signing |
| Price certainty | None until the auction closes | Firm number before you commit |
At that price, a seller paying those fees would net roughly $21,200 to $22,400 before any transport cost, while the buyer paid $26,015. That net figure, not the winning bid, is the number to compare with a direct offer.
When does an auction actually make sense?
Auctions are sometimes the right tool:
- Estate, bank-owned, or dissolution sales where a documented, arm’s-length public sale is required.
- Large mixed-fleet dispersals. If you’re selling ten pieces of varied equipment at once, one consignment beats ten private negotiations.
- You aren’t in a hurry and are willing to bet on two motivated bidders showing up on sale day.
If you’re selling one Equipter and want a firm number with the least hassle, selling direct usually wins. The same comparison applies to the factory’s trade-in program; see trade-in vs. selling your Equipter.

Auction vs. selling direct: FAQ
Who pays the buyer premium at an equipment auction?
The buyer pays it, on top of the winning bid. Because bidders budget for their all-in cost, a larger premium generally means lower bids. Premiums vary by house: 10% of the winning bid at Purple Wave, and 10% capped at $500 plus 2% for online bidders at PA Auction Center.
How long does it take to sell an Equipter at auction?
Plan on weeks. You consign, wait for the next sale, and then wait for settlement; Purple Wave’s standard agreement allows up to 15 business days after the auction or after your title documents arrive. Selling to SLC Rentals typically takes about a week from first photos to payment.
Do auction houses even sell Equipter RB4000s?
Yes. PA Auction Center in Pennsylvania and Bright Star Auctions in Indiana consign them regularly, and national online platforms such as Purple Wave sell them too.
How do I know an SLC offer is fair?
Compare it with your realistic auction net: the likely winning bid minus seller fees and transport, not the headline price. Our pricing guide shows the ranges we work from. If you have questions, talk to us. There’s no pressure, and no commissions or listing fees.
How do I get paid when I sell to SLC?
Most sellers choose direct wire transfer because it is the quickest and easiest, usually within 48 hours of signing. If you would rather have a check, just ask. No commissions or listing fees come out of your payment.
