When searching for a berth, you need to be aware that, just like property transactions in Spain, France and Italy most agents and berth brokers share their data and commissions with each other. The benefit to the owner is that their berth is seen by a much wider audience. However, although we all share data, we DO NOTshare the name of people looking for berths.
This 'sharing' of available berths often proves detrimental to prospective purchasers and sellers alike. For example, if a buyer happens to contact several berth brokers, it leads the seller or their agents to believe that there is more than one person after a berth of that type and size.
It is the supply and demand which affects the ultimate price of a berth, and should it appear that there are several people wanting to purchase a particular berth, even though it may be only one person in reality, it can lead to owners believing that the demand for their berth is greater than it really is. The effect of this, is that you may find yourself paying more for your berth than is necessary, or the seller becoming disappointed by not achieving his sale.
Even when you have identified a berth, it is extremely likely that the berth you find will also be on the listings of several other agents, leading you to the false impression that there are many marina berths available that meet your requirements, and that by shopping around you may find a similar berth that much cheaper. Unfortunately this is rarely the case as marina berths throughout the Mediterranean are in very short supply.
