What you need to sell a flat
A seller needs the building's energy certificate data — it must be in the listing — and a statement of payments and debts from the apartment association. The gain on a sale is taxed at 22 %, unless you lived in the home right up to the sale. The seller is liable for any non-conformity that existed at handover, even if it shows up later.
Energy certificate
A listing for selling or renting out a building or part of one must include the energy certificate (energiamärgis) data: the energy performance figure and class (EhS § 67). The buyer or tenant must be shown the certificate and given a copy when the contract is signed; it is enough if the certificate is visible in the building register (ehitisregister).
In a building with shared heating the certificate is issued for the whole building; a separate certificate for one flat is possible only if there is no shared heating system. Ordering a certificate is an ordinary decision of the apartment association, taken by majority vote (KrtS § 35).
A certificate based on actual consumption is valid for 10 years; one based on designed demand, for 2 years after the building is finished (EhS § 66).
Association statement and a let flat
Get a statement of payments and debts from the association's board in good time: debts for payments already due pass to the buyer.
If the flat is let, the lease passes to the buyer with all its rights and obligations (VÕS § 291).
Liability for defects
The seller is liable for any non-conformity with the contract that existed at handover, even if it appears later (VÕS § 218). Where private individuals sell, the seller is not liable for what the buyer knew or should have known at the time of the deal.
The buyer must report a defect within a reasonable time of finding out about it; a consumer who bought from a company, within 2 months (VÕS § 220). Contract claims expire after 3 years, or 10 years for an intentional breach; claims for building defects under a sale contract do not expire earlier than 5 years after the building was completed (TsÜS § 146).
Known defects — damp, mould, no occupancy permit, problems with access to the building — are better disclosed and written into the contract: one general clause will not protect you from every defect.
Tax on the sale
The gain on a sale is subject to 22 % income tax. The gain is the sale price minus the purchase price and documented costs directly related to the sale (TuMS § 4, § 37).
There is no tax if you lived in the home as your place of residence right up to the sale; this relief applies to no more than one sale every 2 years (TuMS § 15 lg 5–6).
