Building Energy Rating Guide

The energy performance certificate reflects the heating efficiency and energy consumption intensity of the building.

E · this building Higher Energy Demand Noticeable heat loss; typical of older housing stock

Key Risk Factors

  • Built in 1930: technical utility systems require periodic updating and capital maintenance.
  • Estimated energy class E: typically higher heating demand than modern A/B developments. No official certificate on record; the class is inferred from the construction year. Check the actual class and heating costs against the certificate and real bills.
  • Parking: on-grade surface parking on parcel/street; no separate underground garage.
  • Valuation nuance: bank collateral value for a specific unit depends fundamentally on interior finish.

How much rental income can a 3-room apartment generate?

A 3-room apartment in good condition has an estimated market rent of €650–€800 per month, generating an estimated gross yield of 36,3–18,0%.

Is it cheaper to buy or to rent at Koidu tn 81?

Buying means a loan payment of about €98 a month, renting €650–€800 — the loan payment is 86% below the rent. That is 5% (loan) and 34% (rent) of the median gross wage (Tallinn, €2,126, Q2 2026, Statistics Estonia).

Police open data list 20 recorded incidents in the surrounding ~0.7 km² cell over 24 months (incident level: high). Air: of the last 12 months' hourly readings, 50% were in the two best classes and 19% in the two worst (level: elevated). Estimated road noise at the building is 50 dB (Lden).

Does the Estiq online valuation replace a bank-certified appraisal?

No. For a mortgage the bank needs a certified valuer's report under EVS 875 — order a valuation.

How accurate is the Estiq automated valuation (AVM)?

Median error is 9.5% in Tallinn and 12.1% elsewhere in Estonia; 83% of Tallinn estimates fall within ±20% (blind test, May–September 2026). Atypical properties have larger errors — see the methodology.

Where does this data come from?

Sale prices — notarised apartment sales, Maa- ja Ruumiamet; estimates — the Estiq AVM model; rents — Estiq market database (24 months); wages — Statistics Estonia (PA117); building data — building register (EHR); association costs — housing associations' annual reports; noise and air — national noise maps and air monitoring. Figures refresh with every data load and each states its period and sample — see the methodology.

Building data reconciled against the EHR and Land Board (Maa-amet) registries. AVM methodology by Martin Koppel, Estiq real estate valuation advisor (methodology aligned with the EVS 875 standard). This is an automated model estimate, not an EVS 875 appraisal report. Updated 20.10.2026.
