LISTING VERIFIER
Is That €500K Apartment Actually Worth €500K?
Foreign buyers in Lisbon pay 15–30% more than locals for the same properties. It's called the "price variance" — and agents know you don't have local SIR transaction data. Paste any listing. We'll tell you if it's overpriced, duplicated, or a ghost listing — before you waste time viewing it.
Verify any listing in 2 minutes
Enter the key details from any portal listing (price, size, location, basic description). The Listing Verifier compares it against recent SIR transactions and local benchmarks, then flags price variance, likely ghost listings, duplicates, and missing information.

RED FLAGS
What We Catch
⚠️ Price variance (most common)
What it is: Agents know you can't check SIR transaction data. So they price properties 15-30% higher for foreign buyers.
How common: We detect this in about 1 in 3 listings scanned.
What it costs you: €50,000–€150,000+ on a typical Lisbon property.
How we catch it: We compare the listing to actual SIR sales data in the same building and street. If it's 20% above recent transactions, you'll see a red flag.
What to do: Never make an offer without verifying first. If flagged, use the data in your negotiation — or walk away.
Ghost Listings
Properties listed but not actually available. Used to generate leads, test market interest, or bait-and-switch tactics.
Impact
High - Wastes time, leads to pressure tactics
Detection
Cross-reference with multiple sources, agent verification
Unrealistic Prices
Listings priced significantly below market (too good to be true) or way above market. Both indicate problems.
Impact
High - Scams, hidden issues, or unrealistic expectations
Detection
Price analysis vs. comparable properties
Duplicate Listings
Same property listed multiple times with different prices, agents, or descriptions. Indicates confusion or manipulation.
Impact
Medium - Confusion, potential scams
Detection
Image and address matching algorithms
Misleading Images
Stock photos, outdated images, or photos from different properties. Property may look different in person.
Impact
Medium - Wasted viewings, disappointment
Detection
Image reverse search and verification
Incomplete Information
Missing critical details: energy certificate, property taxes, condominium fees, or legal status. May hide problems.
Impact
Medium - Hidden costs or issues
Detection
Information completeness analysis
Real verification example (Príncipe Real)
Listing: 3-bedroom apartment in Príncipe Real, 120m², asking €680,000 ("recently renovated").
Recent SIR sales (last 12 months): similar 3-beds on the same streets have sold between roughly €4,800–€5,200/m². The Listing Verifier benchmarks this property at about €5,000/m², suggesting a fair value band of roughly €580,000–€610,000.
At €680,000, the apartment is priced in the top end of the market for the area with no terrace, no parking, and only cosmetic upgrades. The tool would highlight likely price variance and missing documentation (e.g. no energy certificate, unclear condominium fees) as red flags.
Negotiation insight: instead of treating €680,000 as fixed, you go into talks knowing that a realistic target is closer to €600,000 and that you should request full documentation before scheduling multiple viewings.

FAQ
Frequently Asked Questions
Common questions about listing verification and protecting yourself from overpriced or fraudulent listings.
A foreigner premium is when properties are priced 15-30% above market value specifically targeting foreign buyers who may not know local market prices. Sellers and agents exploit information asymmetry—foreigners often don't have access to SIR transaction data or local market knowledge. Common in tourist areas (Chiado, Bairro Alto) and expat neighborhoods. The Listing Verifier compares listing prices to real market values to identify these premiums.
Combine verification with a buyer's agent
AI verification gives you instant red flags. A vetted buyer's agent gives you market knowledge and can verify listing status directly. Use both for maximum protection.
