Sold Yesterday, Relisted Today at +50%: How to Spot a Flip Markup

The most honest appraisal a house ever receives is its own last sale. Appraisers know it, lenders know it — and flippers count on buyers never looking at it. Price history sits in plain sight on every major listing portal, free, and it takes ninety seconds to read. Here is what it showed on one real West Palm Beach property in the fall of 2026, and the pattern to watch for on any house you are considering.

The timeline: 354 Edmor Rd

The property is a two-bedroom 1970 house on a 7,205 sq ft lot in Edmor Estates, West Palm Beach (ZIP 33405). Its recorded history, in order:

• September 15, 2026 — Listed at $1,100,000 (MLS #B26070321). It went pending the same day.
• October 19, 2026 — Sold for $1,000,000. An arm's-length closing, recorded in the ordinary course.
• October 20, 2026 — Relisted at $1,500,000, under a new MLS number (#B26090397). One day later. Fifty percent more.
• October 26, 2026 — Price cut by $350,000 to $1,150,000, where it sat as the "new" listing — with its days-on-market counter conveniently restarted by the new listing number.

Sources: MLS and listing-portal price history for 354 Edmor Rd (MLS #B26070321 and #B26090397), pulled November 2026.

Read that again slowly, because the whole story is in the dates. Between the $1,000,000 sale and the $1,500,000 ask, one day passed. No renovation crew gutted a kitchen in a day. No addition was framed, no roof replaced, no permit pulled, inspected, and closed. Nothing about the house changed except its owner and its price. Even after the $350,000 cut, the ask stood 15% above what the market had just paid for the identical property, days earlier.

The best comp for a house is the house

Buyers are usually shown comparable sales — similar houses nearby — and those matter. But a comp set is an argument someone assembled. The subject property's own recent sale is not an argument; it is a fact. When a house sold last month, that price reflects a real buyer, a real lender, and usually a real appraisal, all valuing this exact building on this exact lot. Any ask dramatically above it carries a burden of proof: what changed?

At Edmor Rd, the supporting cast agreed with skepticism. The portal's own automated estimate (Zestimate) sat at $1,080,600 — below the $1,150,000 ask. The county's just value was $579,685, with $490,144 of that in the land alone: the dirt under this 1970 two-bedroom is the asset, and land does not get more valuable because a calendar page turned. None of that makes the house "bad." It makes the ask a negotiation anchor, and the $1,000,000 closing the strongest evidence of value on the table.

How to read any price history in 90 seconds

Open the price-history table on the listing (every major portal shows it) and scan for these tells:

• A sale within the last 12 months. Find it, note the price. Any current ask far above it needs a documented reason.
• A relist within days of a sale. A new MLS number resets the "days on market" display and buries the prior listing. The history table still shows both — look for two listing numbers.
• Big jumps with no time gap. A +50% move overnight is a markup, not appreciation. Appreciation has a calendar; markups have a keystroke.
• A fast, large cut after relisting. A $350,000 cut six days in signals the first number was a test balloon. Sellers who test balloons will usually negotiate toward evidence.
• Permit silence. A claimed renovation should have permits in the county record for anything structural, electrical, or plumbed. No permits + no time = no renovation.

How to use it at the table

Anchor to the recorded sale, out loud, in writing: "This property closed at $1,000,000 on October 19. Our offer reflects that price plus documented, permitted improvements since that date." Then ask for the improvement list and permits to justify anything above it. If the seller renovated cosmetically before the purchase — paint, landscaping, staging — those were already in the price the market paid. If the appraisal comes in near the last sale (it often does), the gap becomes the seller's problem to solve with a price cut or the buyer's to cover in cash. Knowing the timeline before you offer is what keeps it from becoming yours by surprise.

A flip is not a scam; buying low and selling high is the business. The markup only works on buyers who never see the first price. It is printed on the same page as the second one — and it is one of the seven records a CurbFacts report puts in front of you before you make an offer.
