To speak with a consultant about a specific property, you will need to contact the developer directly. Developers in Oman include Al Madina A'Zarqa, Muriya, Omran, and Orascom. When you have chosen a suitable property, you will sign a form that states you intend to buy a given property, and the developer will usually ask for a deposit. This allows you to secure any loans you might need before actually signing the contract.
When you sign a contract, you will usually have to make a deposit of 10% of the purchase price. Purchase contracts with a developer are usually drawn up by an independent lawyer and outline the payment schedule. The developer hands the title over to you after the last payment.
If you need to sell your property before it has been completed, the developer will charge you a 2% transfer fee.
