You are likely to find that the contract for the sale of commercial property incorporates the Standard Commercial Property Conditions (Second Edition) and specifies, again, that the property is sold “with vacant possession” or subject to a specific lease.f you seek to provide vacant possession then you must ensure that you pass the two fold test mentioned above and in particular: 1  You must leave the property and ensure that your family/employees leave and, indeed, anyone else-such as trespassers. 2  Take all your goods with you.
