How to Know If a House Is Overpriced: Five Checks and an Offer Formula

An asking price is one person's opinion of what a stranger will pay, printed in large type. Buyers treat it as a fact and negotiate around it; sellers count on exactly that. This guide gives you five checks that turn the opinion back into evidence, a way to read the tempo of the local market, and a formula for the offer itself: an anchor, a walk-away number and the clauses that protect you. It is the pricing chapter of our pre-offer checklist, what to check before buying a house; the value question comes first because it changes every other number in the deal.

Why the asking price is a marketing number

Three inputs set most list prices, and only one of them is evidence. The agent brings a comparative market analysis built on recent sales. The seller brings a target: the loan payoff, the cash needed for the next purchase, the figure a neighbor got three years ago. And the listing appointment brings competition between agents, some of whom win the contract by naming the highest number in the room and planning the cut for later. NAR's Code of Ethics has a rule aimed at that habit. Standard of Practice 1-3 forbids a REALTOR® who is trying to win a listing from deliberately misleading the owner about market value, and Standard of Practice 11-1 requires an opinion of value prepared for any purpose other than winning a listing or helping a buyer frame an offer to state its basis, its date and whether the property was inspected³. Optimism is not prohibited, and a listing's price history usually shows where it crept in. How sellers and their agents pick between at-market, just-below and aspirational strategies is set out in the guide to pricing a house to sell; read it as the other side's playbook.

The national backdrop in 2026 favors the skeptical buyer. The median US list price in August 2026 was $424,500, 1.0 percent lower than in July and 1.3 percent lower than a year earlier, the tenth straight month of year-over-year declines². Local markets diverge from that, which is the point of checking locally: in Los Angeles County the median existing single-family home went for $946,950 in August 2026, 1.7 percent more than a year before, while the wider Los Angeles metro area stood at $850,000 and California at $901,420⁴. A list price that would be fair in one of those three geographies is wrong in the other two.

How to know if a house is overpriced: five checks

Comps first, always. Fannie Mae's Selling Guide, the rulebook for appraisals behind conforming mortgages, requires three closed sales at minimum, normally no older than 12 months, and treats current listings and contract offerings as supporting data only¹. Your offer will be tested against those sales a month after acceptance, so build it on them now. Where to find closed prices, how to verify them and how to adjust them is covered in the guide to finding comparable sales; why smaller homes carry a higher price per square foot, and how that skews check two, is explained in the price per square foot guide.

Checks three to five describe the seller's position, not the house's value. A listing at 95 days in a ZIP code where the median is 40 has told the market something, and the market has answered. The sale-to-list ratio adds the missing piece: if closed sales in the neighborhood are running at 96 to 98 percent of their final list price, an offer at 97 percent is normal, not insulting.

Reading market tempo: days on market, inventory and pending sales

Tempo is the speed at which the local market clears, and it decides how much of the five-check discount you can actually collect. Four national series set the frame for August 2026: 60 median days on market, unchanged from a year earlier; active listings at 1,140,000, up 3.6 percent year over year and the fastest growth so far in 2026; new listings of 401,760, 0.1 percent below a year earlier²; and the National Association of REALTORS® Pending Home Sales Index, which rose 0.3 percent from July but fell 4.7 percent from a year earlier, with declines in all four regions⁷. More homes for sale, fewer contracts signed: that is a market in which the seller waits for the buyer.

The financing side tightens the screw. Freddie Mac's weekly survey for September 24, 2026 averaged the 30-year fixed at 7.03 percent; twelve months earlier the same series read 6.30 percent⁸. Every buyer at a given monthly budget can borrow less than last year, so the pool of buyers for any list price is thinner. Read the local version of each series before you write: Realtor.com's files carry days on market and price reductions down to ZIP code⁵, and an agent can pull the same month's closed sales from the MLS.

Condition, disclosures and the photos-versus-reality discount

Wide-angle lenses, staging and a sunny afternoon add tens of thousands of dollars to a listing's apparent value, and the gap closes the moment you walk in. Note what the photos skipped: the roof, the electrical panel, the yard's slope, the neighbor's wall. Then ask for the seller's disclosures before you offer, even where the law only requires delivery later. In California the seller's disclosures about the property go on the Real Estate Transfer Disclosure Statement, the form prescribed by Civil Code § 1102.6⁹, and a second form, the Natural Hazard Disclosure Statement under § 1103.2, states whether the lot sits in a FEMA special flood hazard area, a high or very high fire hazard severity zone, an earthquake fault or seismic hazard zone or a dam inundation area¹⁰; the flood zone by address guide shows how to read the FEMA map yourself before either form arrives. Two more location checks belong in this pass and cost nothing: the official crime statistics for the area, read the way the crime rate by address guide describes, and the modeled noise level at the address, which the road noise and property value guide shows how to look up.

Everything you find here is either a price adjustment or a contingency. A roof at the end of its life is a number to subtract from the comps' indicated value, in writing, in the offer. An unpermitted garage conversion is a question for the building department and an inspection item. This is general information, not legal or tax advice.

Building the offer: anchor, walk-away number, escalation clause, contingencies

Anchor. Your opening number should sit inside the range the adjusted comparables support, toward its lower end when tempo is slow and toward its upper end when the house is fresh and showing well. An anchor below the range invites a rejection without a counter; an anchor at the ask ends the negotiation before it starts.

Walk-away number. Decide the highest price you will pay before you write anything, and derive it from two figures: the top of the indicated range, and the monthly payment you can carry. At 7.03 percent over 30 years, every $10,000 of borrowed price adds about $67 a month in principal and interest (computed on the survey rate⁸). A $30,000 stretch is $200 a month for three decades.

Escalation clause. In a competitive situation, an escalation clause raises your offer automatically above a competing bona fide offer by a set increment up to a cap. Set the cap at your walk-away number, require proof of the competing offer, and remember that the clause reveals your maximum to the seller.

Contingencies. Inspection, financing and appraisal contingencies let you leave the contract if the house, the loan or the lender's value falls short. The appraisal contingency matters most when you offer above the range: if the appraiser's three comparables¹ do not reach your price, the lender lends on the lower figure and you either cover the gap in cash or renegotiate. Earnest money and a short inspection period make an offer stronger without adding a dollar to the price.

A $749,000 Los Angeles bungalow tested against a $700,000 to $735,000 range

A hypothetical example with invented figures. A two-bedroom, one-bath bungalow of 1,050 square feet, built in 1948, on an interior street in the eastern San Gabriel Valley of Los Angeles County, listed at $749,000 after one cut from $775,000, 74 days on the market. Average condition, original kitchen, detached one-car garage. The county's median single-family price stood at $946,950 in the same month⁴; this is a starter house well below it.

The five checks, in order. Comps: the adjusted prices cluster between $702,000 and $733,000, so the indicated range is $700,000 to $735,000 and the ask of $749,000 is 2 percent above the top and 7 percent above the bottom. Price per square foot: the listing asks $713 against $689 to $699 for the three sales. Days on market: 74 against a national median of 60², and the local ZIP code median, pulled from Realtor.com's files⁵, is 45 in this example. Price cuts: one, of 3.4 percent, in a month when a fifth of US listings were cutting². Sale-to-list: the agent's MLS report for the ZIP code shows closed sales at 97 percent of final list in the example.

The offer: anchor $705,000, walk-away $730,000, a 12-day inspection period, financing and appraisal contingencies, earnest money of 3 percent. The cover letter states the three sales, the adjusted range and the tempo in four sentences. Two things the buyer does not do: offer "5 percent under asking" ($711,550), which would credit the seller's optimism; or pay the ask because the house is charming, which with 20 percent down and a 7.03 percent loan⁸ would add about $235 a month to the payment, against the anchor, for 30 years.

The value range and market tempo that go into the offer letter

CheckValue produces an AI valuation report for one address, and for a buyer its use is narrow and specific: in about two minutes it delivers the parts of the five checks that take an afternoon by hand. The value range with its point estimate is check one in written form, resting on comparable sales the report lists with their adjustments. Price per square foot compared with the district average is check two. The market tempo, the report's estimate of time to sell in the area, is the local half of check three, the piece a national median cannot give you. Because identical inputs for an address return an identical result, the range you attach to your offer is the same range the seller's agent would get by running it, which makes it hard to dismiss as a buyer's wishful number.

What it is not: an appraisal, an inspection or a forecast of how many other buyers will bid this week. It does not look inside the house, and the lender will still order its own appraisal. Enter the listing's facts as advertised and check the value range and market tempo for the listing address in the preview before you decide whether to buy the full report; the sample reports include a completed Los Angeles report with the range, the comparables and the tempo section.

When to walk away

• The seller counters above the top of the indicated range and the tempo says other buyers are not lining up²⁷: let the listing age.
• The appraisal comes in below the contract price and the seller refuses to meet it: the lender has just told you the comps' verdict¹.
• The disclosures⁹¹⁰ or the inspection turn up work you cannot price with confidence: a foundation, a slope, a title issue.
• The monthly payment only works if you refinance later; at 7.03 percent⁸ that is a bet, not a plan.
• You have started explaining to yourself why this house is the exception to the comps.
