# What you can and can't claim in a property ad
A listing promises "guaranteed 8% rental yield" and "five minutes to the station." Neither survives a regulator's second look. The yield depends on occupancy nobody can guarantee, and the walk was timed by an agent who jogged it. Both are the kind of claim that gets ads pulled, fines issued, and brokerages named publicly by consumer protection bodies. This lesson shows you how to write ad copy that sells hard without crossing the line into misrepresentation.
Real estate marketing sits under general advertising law plus sector-specific consumer protection rules, because a home or investment property is a high-value, low-frequency purchase where buyers can't easily "try before they buy." Regulators treat this asymmetry seriously.
In the UK, the Advertising Standards Authority (ASA), the independent regulator of ads across media, enforces the CAP Code (Committee of Advertising Practice Code), which requires claims to be "legal, decent, honest and truthful." The ASA has upheld complaints against agents for unqualified "guaranteed yield" claims on buy-to-let developments, because a yield is a forecast, not a fact (ASA rulings database).
In the US, the Federal Trade Commission (FTC) polices deceptive advertising under Section 5 of the FTC Act, and the National Association of Realtors (NAR) Code of Ethics adds member-level obligations around truthful representation. Fair housing claims are policed separately and heavily, more on that below.
Across the EU, the Unfair Commercial Practices Directive (UCPD)
The common thread: a claim is fine if it's substantiated, qualified, and not misleading by omission. It's a problem if it's a guess dressed as a fact.
Rental yield, capital appreciation, occupancy rates: none of these can be guaranteed unless there's a contractual mechanism actually backing the guarantee (for example, a developer offering a fixed rental payment for year one, in writing, as part of the sale contract). Absent that, use "estimated," "projected," or "based on comparable lettings in the area as of [date]."
Rewrite example:
"Five minutes to the station" is a classic ASA complaint magnet. The standard defense regulators expect: state the method. Was it walked, driven, or estimated by mapping software?
Rewrite example:
"Best value in the area," "unbeatable location," "hottest investment opportunity." These are usually treated as puffery (exaggeration no reasonable person would take literally) and tolerated in most jurisdictions, but they become actionable the moment they imply a factual, checkable claim. "Best value" is puffery. "Cheapest price per square foot in the postcode" is a factual claim that must be true and sourced.
This is the highest-risk category in the US. The Fair Housing Act prohibits ads that indicate a preference or limitation based on race, color, religion, sex, national origin, familial status, or disability. This is not about intent, it's about how the ad reads.
Phrases like "perfect for young professionals," "no kids," "walking distance to church," or "ideal for able-bodied tenants" have all triggered enforcement action or fair housing complaints, even when unintentional. The Department of Housing and Urban Development (HUD) actively monitors advertising language, including on platforms like Facebook, which paid a settlement over ad-targeting tools that allowed housing advertisers to exclude protected groups (HUD fair housing advertising guidance).
In the UK and EU, the Equality Act 2010 and equivalent national laws impose similar restrictions under different mechanics, barring discriminatory preferences in housing ads.
Rewrite example:
"Eco-friendly," "green building," and "energy efficient" are increasingly regulated as greenwashing risks. In the EU, the Energy Performance of Buildings Directive (EPBD) requires an Energy Performance Certificate (EPC) to be referenced in marketing material for sale or rental listings, with the actual rating (A to G) disclosed, not just a vague sustainability claim. The UK has parallel EPC disclosure rules enforced by local authorities. Advertising "energy efficient" without citing the EPC band is a common compliance gap.
Rewrite example:
Before a listing or campaign goes live, especially for new developments, run it through a structured check rather than relying on a single reviewer's judgment. A practical pre-launch checklist:
1. Every quantitative claim has a source and a date. Yield figures, square footage, distances, comparable prices: each needs a named source (agency data, official floor plan, mapping tool) and the date it was pulled.
2. Every superlative is either provably true or downgraded to opinion language. "Best" and "unbeatable" should be rare and defensible; prefer specific, checkable comparisons.
3. No claim implies a preference for or against a protected group. Read the copy specifically hunting for lifestyle language ("perfect for," "ideal for") that could be read as exclusionary.
4. EPC or equivalent energy disclosure is present wherever "green," "efficient," or "sustainable" language appears.
5. Forecasts are labeled as forecasts. Rental income, appreciation, ROIROIReturn on Investment: the ratio of net profit to the cost of an investment. A 300% ROI means each dollar invested returns $3.Voir la définition complète → projections: all need "estimated" or "projected" plus the basis.
6. Images match reality. Staged photography, virtual staging, or renderings for off-plan developments must be clearly labeled as such (many regulators, including the ASA, require "computer-generated image" or "CGI" labeling on unbuilt properties).
A simple internal flagging structure works well operationally:
CLAIM: "5 minutes to the tube"
STATUS: unverified
FIX: replace with distance + method + estimated walk time
OWNER: listings copy team
DEADLINE: before MLS/portal uploadVérification des acquis

2. An agent advertises a buy-to-let property with 'guaranteed 8% rental yield.' Why is this claim problematic under advertising rules like the CAP Code?

Regulators rarely fine over a single ad. Action tends to follow patterns: repeat offenders, egregious fair housing violations, or claims tied directly to financial loss (an investor who bought based on a "guaranteed yield" that never materialized has a stronger complaint than someone annoyed about a walk time).
That said, portals themselves increasingly self-police. Zillow, Rightmove, and other major listing platforms have their own content policies that mirror regulatory standards, partly to protect themselves from liability as publishers of third-party content. A listing rejected by a portal's automated compliance filter (for banned words like "guaranteed" or unlabeled superlatives) never even reaches the regulator, it just costs you time and a rewrite.
