For many business the facts of running a business mean that you are leasing in some form or another an office, a shop or other type of facility to operate your business from. While it is possible to work with No Fixed Office, there is still a great number of businesses that do happen to need an office or really cannot get by without having the retail store front. To be honest to some extent it is not so much the need of the business but the need of the consumer to see this.
If you do lease any type of premises for your business by default you are going to have a Landlord. The landlord actually has a great deal of control in your business, while you do have a contract for the most part defining the bounds of your relationship, much of the time the decision can be an easy one from either perspective that points of contention do come up.
There is a way to at least attempt avoiding a situation with the landlord becoming poor. The idea starts when you first sign the lease, start a relationship with the landlord, just as if they were a customer. Send them a thank-you for allowing you to use the facilities. Let them know about what you are doing in your business which may impact them. For the most part, just a few simple things can place you in a better position when there is a problem with the landlord. They may be a little more giving or more willing to listen.
The other benefit that you may find is that later on down the track when you are looking to renew your lease, the landlord may be more willing to continue with the same terms, or extend the term at the same conditions. It can be a real win win for both you and the landlord. They know that they have a good tenant, and you know you are safe in your location.
