When a land lord wants to buy out my lease, what factors are to be considered so that I am fully compensated ? - lease factor

Their property was recently purchased and now have a new earth, Lord, to buy my lease offered. I am a tenant and have a good new year and a half before my lease is up. How much can I expect and what are the factors that determine the amount? I will not be exploited and would like to know my rights, so you can be adequately compensated.
