9 SALES EXPRESSIONS OF INTEREST Expressions of Interest, EOI or Best Offer By… is a method where buyers have to submit an offer by a specified date. At the end of the sale period you as the homeowner can review submissions and choose the expression of interest that appeals to you the most. If an acceptable offer is not found, the property may be placed on the market as a private treaty sale or EOI may be called again. Expressions of interest provide you with the benefits of a private treaty sale but with the urgency of an auction without the potential stress. Buyers however are submitting offers ‘blind’ without much feedback on the strength of their offer. This can sometimes be frustrating for the buyer.
