Realistically a decent mini-split that won't break in a year and won't make too much noise starts at ~€600-800 + €400 installation in a low-labor-cost country (Latvia), in high-labor-cost countries such as Germany the installation bit might be twice-thrice as expensive.

Relative to buying the house/apartment in the first place, that's still not much money.
