SMART VALUATION (AVM)
Real Transaction Prices, Not Just Asking Prices
See real property values using SIR data—the same ground truth used by Portuguese banks. Automated Valuation Model (AVM) provides ±5% accuracy based on actual transaction data so you can see the gap between optimistic asking prices and what similar homes really sold for before you decide how far to negotiate.

What happens if you rely only on asking prices
Many foreign buyers base their offers on what they see on the portals: asking prices and agent language about "market value." But in Lisbon, listing prices are marketing positions, not ground truth. Without transaction data, it's hard to know whether you are paying a fair price or quietly funding a foreigner premium.
Smart Valuation uses SIR records—the same data banks rely on for mortgage decisions—to anchor your expectations in what comparable properties in the same building, street, and neighbourhood actually sold for. That context lets you calibrate offers, push back on obvious overpricing, and walk away from listings that simply don't make sense for the local market.

VALUATION METHODOLOGY
Factors That Determine Property Value
Comparable Sales
40%Recent sales of similar properties in the same neighborhood. This is the anchor for value: what buyers have actually paid nearby in the last 12–24 months, not what sellers asked for.
Property Characteristics
30%Size, condition, age, features, views, floor level, and property type—everything that makes this specific property worth more or less than its neighbours, adjusted for quality and condition.
Location & Neighborhood
20%Neighborhood desirability, proximity to amenities, transport links, schools, and market perception. A top street in a prime area prices differently from an equivalent apartment in an emerging location.
Market Conditions
10%Current market trends, supply and demand, interest rates, and economic factors affecting property values. This layer adjusts valuations for whether the market is heating up, cooling down, or moving sideways.
