In general around 1% - 1,5% of the actual sale price + 18% vat-tax over that amount. This includes all necessary contracts for closure, due diligence from the property, and the steps to transfer the Certificate of Title in the name of the new owner. The buyer pays for legal fees. The seller pays the real estate commission. Example on a property from 300,000 USD: 1% = 3,000 USD. 18% over that amount is 540 USD so total legal fees 3,540 USD.
