The use, access and management of a property are key issues that can often be overlooked by artists when negotiating a contract.
For example, if you have a job, do you need access only in the evenings? Is there 24-hour security? The access should be suitable for your usage; if it is not, or not negotiable, then you may be wasting money in taking on a lease in the first place.
Negotiate all of this before you sign any contract, or check it is in the lease.
