Renting first remains the cautious choice in an unfamiliar country. Neighbourhoods change character in August and in February, and nearby construction shows up after a few weeks. One rental cycle costs far less than unwinding a bad purchase.
Buying becomes reasonable once the horizon is long enough. The costs of buying and selling remain considerable, so a short stay seldom covers them. The usual rule of thumb suggests a horizon of several years before ownership pays off.
Financing shifts the calculation in both directions. Overseas purchasers typically encounter stricter lending terms and less favourable rates than domestic buyers. If no local mortgage is available, the whole plan means a full cash commitment, which reshapes the opportunity cost.
Renting protects freedom of movement. A shift in circumstances, a family situation or a change in immigration policy can be absorbed with a few months' notice, rather than a buy property in sofia sale in a slow market.

Ownership brings things a lease does not: stability of costs, the freedom to renovate, and a tangible asset you actually hold. In some countries, being an owner also supports a residency case. The practical answer in most situations is renting while you learn the market and buying afterwards.
