Selling a Bulgarian apartment
The three-year exemption is the single most valuable rule in Bulgarian property tax — and the one most foreign owners discover too late.
Most guides stop at the purchase. The exit is where the return is actually determined, and Bulgaria has one rule that dominates everything else: hold a residential property for long enough and the gain is tax-free.
Capital gains: the exemptions
Bulgarian capital gains on property are taxed at 10%, with two exemptions that make most private sales tax-free:
- One residential property sold more than three years after acquisition is exempt.
- Up to two properties sold more than five years after acquisition are exempt.
Two practical consequences. First, the timing of a sale around those anniversaries is worth real money — check the acquisition date on your deed before you list. Second, this is precisely why under-declaring the purchase price is such a bad idea: if an exemption does not apply, your taxable gain is measured against the declared purchase price, and the "saving" made at purchase becomes a much larger bill at sale. Non-residents should also check their home country's treatment, which the Bulgarian exemption does not govern.
What selling costs
| Item | Typical | Notes |
|---|---|---|
| Agency commission | 2–3% + VAT | Negotiable; sole-agency terms usually cheaper |
| Notary fees | Statutory scale | Often split with the buyer by agreement |
| Certificates and extracts | €50–150 | Tax valuation, skitsa, encumbrance check |
| Outstanding building charges | Varies | Must be cleared; they attach to the property |
| Capital gains tax | 0% or 10% | Zero if an exemption applies |
| Translation / power of attorney | €150–300 | If selling remotely |
A typical exempt sale costs 3–4.5% all in, which is cheaper than most European markets.
Pricing without a price register
Bulgaria publishes no register of achieved sale prices, so neither you nor your buyer can look up what the flat next door actually sold for. Three practical substitutes:
- Asking-price medians for your neighbourhood. Our price index gives the median per square metre and by flat size for every Sofia neighbourhood, from 18,058 live listings.
- Time on market. A flat that has been advertised for three months is priced above the market, whatever the asking figure claims.
- Two or three agent valuations, treated sceptically: an agent wins the instruction by quoting high and then spends two months persuading you to reduce.
Expect to settle 3–8% below your asking price. Pricing close to the market from day one sells faster and usually higher than starting optimistically and chasing the market down.
What actually sells a Sofia flat
- Clean paperwork. A current tax valuation, skitsa, clear title and a zero balance with the building manager remove every excuse for delay.
- A finished bathroom and kitchen. Bulgarian buyers discount an unrenovated flat by more than the renovation costs — see renovation costs.
- Honest photographs and a floor plan. Most Sofia listings have neither, so both stand out.
- The building's story. Insulated block, roof done, lift serviced — say so. Buyers who know the market are pricing exactly these things.
- Availability. Viewings happen on weekday evenings. If you are abroad, appoint someone who can open the door at short notice.
The sale process and timing
Once a buyer is found: preliminary contract with a 10% deposit, then the notary deed and registration. Three to six weeks is normal for a cash buyer, six to ten with a mortgage. If you are selling remotely you will need a notarised and apostilled power of attorney — arrange it before you need it, because it takes two to three weeks and no completion waits for it.
Sofia's most liquid stock is the mainstream two- and three-room flat in a metro-served estate. Studios, ground floors and peripheral complexes take longer, which is worth knowing at purchase rather than at sale.

Frequently asked questions
Do I pay capital gains tax when selling property in Bulgaria?
Gains are taxed at 10%, but one residential property sold more than three years after acquisition is exempt, and up to two properties sold after five years are exempt. Check the acquisition date on your deed before listing.
How much does it cost to sell a property in Bulgaria?
Typically 3–4.5% all in for an exempt sale: agency commission of 2–3% plus VAT, notary fees on the statutory scale, certificates at €50–150, and any outstanding building charges, which must be cleared.
How long does it take to sell an apartment in Sofia?
Finding a buyer depends on price and stock type; the transaction itself runs three to six weeks for a cash buyer and six to ten with a mortgage.
How do I price my property without a price register?
Bulgaria publishes no achieved-price data. Use neighbourhood asking-price medians — our price index covers all 136 — plus time-on-market signals and two or three agent valuations treated sceptically.
Can I sell my Bulgarian property from abroad?
Yes, with a notarised and apostilled power of attorney. Allow two to three weeks to arrange it, and appoint someone locally who can handle viewings.
Why is under-declaring the purchase price a problem when I sell?
Because your taxable gain is measured against the declared purchase price. If no exemption applies, the tax saved at purchase becomes a far larger bill at sale — quite apart from the illegality.
What makes a Sofia flat sell faster?
Clean paperwork, a finished kitchen and bathroom, honest photographs with a floor plan, a building with its roof and lift in order, and realistic pricing from day one.
Which properties are hardest to sell in Bulgaria?
Studios, ground floors, rural village houses and resort complex apartments. Mainstream two- and three-room flats in metro-served Sofia estates are the most liquid.
