Hi there

I am a new landlord and drafting my first tenancy agreement.  I will probably download one from Lawpack and make amendments then have it check out by a solicitor. My intention is to do a 6 months AST at first, then let it run monthly. 

The lender has given me a page of "Tenancy Conditions" to conform to and there is one point that remains quite obscure.

"The tenancy agreement can be renewed without our consent. Options to renew are acceptable as long as they are limited to one renewal only, on the same term as the existing lease, and the option clause must itself exclude the option to renew so that there is no perpetually renewable lease"

I cannot make sense of this condition.  What are these "Options"?  Why only one renewal?
