You may wish to move to a more suitable property - maybe somewhere smaller or in a different location.  In this case the landlord may sell the house you were in and set you up as a tenant in another property. 

Think about it - if you have been a good tenant, why would your landlord not be happy to accommodate your request to move.

If your own landlord cannot help, he can call on our network of experienced landlords who will no doubt be able to help.  Again, it's great for a landlord to have a good tenant.  Everyone wins.
