Saffie is right. Unless you specifically asked on the original application to be allowed to sell or rent then these will be written up on the order as not allowed. All it means is that the Court wasn't asked to grant that permission and it doesn't mean that they would not have granted it, or that they won't if you apply now.
Keeping the 'powers' of a Deputy to what they actually need to do saves on the Deputy bond, which can increase significantly if the selling of property is allowed.
So that's the reason for the Court keeping bog standard orders quite limited. On the other hand, the selling of properties by Deputies is nothing out of the ordinary. In fact I'd hazard a guess that this is what happens in most cases, to fund care costs. If you feel that a sale would be best in your particular circumstances , even if the money isn't needed for funding care but because you don't want the hassle of dealing with an empty house, then go back to the Court with another application and ask them for an order that will allow you to proceed.
