Real Estate — Offer Tracker

An editorial offer-management board for a single listing, pairing a photographic property header with a live stack of buyer offers. Each row shows the buyer, agent, bid amount with over- or under-ask delta, cash or financed badge, contingency terms, status pill, and timestamp. A counter-offer composer logs the seller's response, while accept, reject, and reopen actions recompute the highest and leading offer, summary stats, and the spread against list price in real time.

Offer Tracker

A focused negotiation board for the listing agent on a single property. A photographic, gradient-rendered header anchors the page with the list price, key facts, and a running readout of the current leading offer. Beneath it, a summary band tallies active offers, the highest bid, the spread over or under asking, and how many bids are all-cash.

Every offer is a refined card: buyer and representing brokerage, the bid amount with an over- or under-ask delta, a cash or financed badge, contingency term chips, a colour-coded status pill (Submitted, Countered, Accepted, Rejected) and a relative timestamp. The leading offer is highlighted with a brass accent and a “Leading” badge — accepting one bid automatically steps any prior acceptance back, and rejecting a bid pulls it out of the leading calculation.

The counter-offer composer lets the seller respond to any open offer with a revised price and toggleable terms. Sending a counter flips the buyer’s offer to Countered and logs the seller’s counter as a new line in the history, then recomputes the highest bid, spread, and leading offer. Inputs format thousands as you type, and a small toast confirms each action.
