You can rent a 7 bedroom villa from anywhere between 8,000 QAR/month for a villa in Umm Salal to around 35,000 QAR/month for luxurious villas in the West Bay area (including West Bay Lagoon). Some of these 7 bedroom villas are commercial villas, which means you can run a licensed business from the premises. Keep in mind that when you're looking for a villa for rent, one of the decisions you will find yourself making is whether you need one that is furnished, partly furnished, or unfurnished. Finding a fully furnished 7 bedroom villa can be impossible, but if you don't have furniture and don't want the hassle then try speaking to the landlord and perhaps the can arrange it for you. Alternatively you can find companies that will supply and assemble all of your furniture for you. It's not uncommon for 7 bedroom villas to have luxurious features such as private swimming pools and an elevator.
