Auctions create urgency, competition, and transparency that can drive prices above expectations.

When Private Treaty Works Best

  • Complex site — unusual constraints require developer due diligence
  • Conditional sale — DA conditions, extended settlement, or leaseback needed
  • Limited buyers — the site suits a specific developer type
  • Premium pricing — you want to negotiate from a strong position without public price disclosure

Private treaty allows more flexibility in terms and conditions, which can be important for development sites.

The ACRES Approach

ACRES recommends the sales method based on each site's specific characteristics. Often, an expressions of interest (EOI) process offers the best of both worlds — creating competition while allowing conditional offers.

Frequently Asked Questions

Which method typically achieves a higher price?

It depends on the site. High-demand sites often perform best at auction. Complex sites with limited buyers typically achieve more through private treaty.

Can developers include conditions at auction?

Standard auctions are unconditional. However, many development site sales use an EOI process that allows conditional offers with a competitive framework.
