I would be interested in seeing the language and form for my own education.

Some sellers are dishonest not thinking some liens will be caught and others are so distraught with problems they are dealing with they have no clue what is attached lien wise to the property.This is why if you write the offer to expire with proper language you CAN but are NOT obligated to accept once the bank approves.

What language should I use in the new lease to indicate to the renter that I have promised him that I will include his lease in any purchase agreement and advertisements indicating the buyer must honor the lease?

I'll have the realtor make sure there is some language in the contract that states, the tenant leases come with the purchase of the property.  

Be sure to include the specific language that is required in an eviction notice and be sure to properly serve the tenant.

Fun fact: some hugely disproportionate percentage of ^these^ phone calls are from folks who it is clear speak English as a second language.

@Franklin McGuire I do believe the newer residential rental agreement has some language about early termination, but the safest thing to do is to just write your terms in the additional terms lines near the end of the lease.

What is in the language of the parking lot leases?  

hello BP familyMy name is Stefan Chirila and moved in California from Romania in 2011. happy to be here and finally taking  my first action and come on board.I am 32 years old, did sport at the highest level all my life, I am married and Civil Engineer, when I moved in US I started working as a labor for a small construction company(didn't have rights, and not shame about that), throughout time I learned the language and got my rights and equivalent my degrees and eventually started to work in construction management as an assistant Superintendent for a very big GC, everything is good happy with my job with my growth in US in a very short time, but always had in me the filling that I can do more then just working hard and make money for someone else, always dream about financial freedom, never actually took actions in that direction. 

--Here I am looking at their body language and to see how confident and knowledgeable they are about taking on the job.
