Multi-par auction software for land and real estate.
Let buyers compete on individual parcels, combinations, and the whole group at once — and sell the property whichever way pays the most. Unovance Global runs the parcel math in real time on a branded platform you own.
A multi-par auction sells a property as several parcels at the same time. Bidders can pursue a single tract, a combination of adjacent parcels, or the entire group — and the seller takes the arrangement of bids that yields the highest aggregate total.
It is the format of choice for land, farms, and development real estate, where the value of the whole and the sum of the pieces are rarely equal. Rather than betting in advance on how to slice the offering, the auctioneer lets local single-parcel buyers and whole-property assemblage buyers compete directly against one another.
Unovance handles the hard part: continuously recomputing every valid bid combination and showing the leading scenario live. You keep control of reserves and confirmation — and because the event runs on your branded platform, the buyers and data belong to you, not a rented marketplace audience.
Everything you need to run parcel-by-parcel competition.
Bid by parcel, combo, or whole
Buyers can win a single tract, a combination of adjacent parcels, or the entire group — all in the same live event, with the platform always offering the parcels in the way that pays the seller most.
Real-time high-bid math
The engine continuously recalculates which standing bids — individual, combination, or whole — produce the highest aggregate total, so the leading scenario is always transparent on screen.
Flexible parcel combinations
Define which tracts can group together and which must sell as a set. Buyers wanting to assemble a contiguous holding can bid the combination directly without an off-platform negotiation.
Reserves and seller confirmation
Set per-parcel and aggregate reserves, then confirm or pass at the close. You keep control of the sell decision while the format pushes competition between local and assemblage buyers.
Frequently asked questions
What is a multi-par auction?+
A multi-par (multiple-parcel) auction divides a property into individual tracts that are sold simultaneously. Bidders compete on single parcels, on combinations of parcels, or on the entire group as a whole. The seller takes whichever arrangement of bids produces the highest total — capturing both single-tract buyers and buyers who want the whole assemblage.
Why is multi-par used for land and real estate?+
Larger land tracts often sell for more when broken into parcels, because each piece reaches its best-fit buyer — yet a single buyer may still value the whole. Multi-par lets both compete at once, so the seller never has to guess in advance whether the property is worth more divided or together.
How does the software decide who wins?+
Throughout the event, Unovance recalculates every valid combination of standing bids and surfaces the scenario with the highest aggregate value. Buyers always see the current leading arrangement and the amount they would need to bid to overtake it, keeping the contest honest and fast.
Can I run multi-par alongside my other auctions?+
Yes. Multi-par is one of 22 formats on the Unovance platform. You can run timed, live webcast, sealed-bid, and multi-par events from the same branded site and the same bidder base — so the land buyers you earn stay yours, not a marketplace’s.
