Housing prices are controlled by local supply & demand; there's no way housing is going to be remotely comparable between let's say the UK and Romania; the majority of properties would stay empty forever if they were priced like in the UK.

Same thing for most consumer goods - they have a (very low) base price and the rest is pure profit margin which is adjusted according to the local purchasing power. Consumer goods in Romania would be much cheaper than in a Western European country; whether by existing manufacturers lowering their profit margins to match local purchasing power, or other manufacturers managing to fill this gap in the market by selling at more affordable prices.
