How Opentero Works

Find real value — not just similar listings

We analyze every property across multiple signals to estimate its true market value, rental potential, and investment quality.

Unlike basic comparable listings, Opentero looks at demand, condition, environment, and micro-location — not just price per m².

Signals

What we analyze

Every listing is enriched with signals across several key dimensions.

Location quality

Access to city center, transport, and everyday essentials — not just distance, but real livability.

Property details

Size, layout, building type, floor, and amenities.

Local market data

Prices of similar homes nearby — adjusted for real differences.

Demand & liquidity

How fast similar properties sell, how much attention they get, and how prices change over time.

Property condition

We analyze photos to estimate renovation level, light, and overall appeal.

Environment

Greenery, noise, and surrounding conditions that affect long-term value.

Value & rent

Estimated value & rent

Three numbers, one clear picture.

  • Market sale value. What the property is likely worth
  • Rental income. Expected monthly rent
  • Yield. Potential return based on current price

You instantly see whether a listing is undervalued, fairly priced, or overpriced.

Confidence score

Every estimate comes with a confidence level so you know how much to trust it — tight uncertainty on familiar data, wider ranges on atypical listings.

Deal score

One score, 0 to 10

Each listing is ranked across multiple factors — not just one.

  • Price advantage vs estimated value
  • Rental potential
  • Listing freshness

High scores indicate strong opportunities across multiple factors — not just one.

Transparency

Understand why

Instead of a black box, you get clear, human-readable drivers of the estimate.

01
Location
Micro-geography: district tier, transit, schools, parks.
02
Condition
Photos classify renovation level, light, and appeal.
03
Local pricing
Similar sold/listed properties nearby, area-adjusted.
04
Demand
View velocity and time-on-market tell us about interest.
05
Building
Year, series, materials, floor — features that shift value.
Scenarios

Investment scenarios

We estimate costs, returns, and payback so you can evaluate risk before making a decision.

Conservative
Cautious assumptions: lower rent, higher vacancy.
Expected
Typical market conditions, median outcomes.
Optimistic
Favorable conditions: full occupancy, market tailwind.
Beyond comps

Why not just use similar listings?

Comparable listings alone can be misleading. Opentero combines every signal into a single, consistent estimate.
