Yet having finally found those we can trust, (we may question at length their objections), we heed their insight/advice.

Adding and removing codes for guests, etc.Also, I never got a clear answer when I researched it last, what's the code length on the lockstate time based ones? 

Why don't you keep it simple and just say I propose the following:I wish to enter into a lease and option with you what ever the sellers name is, under the following terms, The name of the terms such as rent amount, length of term exercise price etc.If you have a copy of the deed use the legal descriptionI would say something like this agreement is not binding and the seller(s) agrees to sign a lease and option within three business days days of signing this letter of intent with the buyerTo protect yourself I would not sign actually in the presence of the sellers at their home, I would do it in the title company or lawyers office

And it's triggered by any lease that contains an option to purchase the property, regardless of the length of the lease.It is a shame that people who lack integrity, honesty, scrupules and moral character think nothing of teaching others how to be like them.

In regards to a contract between the 2 of us what should it state and is there a length requirement.

Despite its length, it's actually a pretty easy read. 

@Francois GuerrierThis topic is talked at length everywhere.There is no correct answer.

It depends on the size of the home, the income potential, the length of contract and how often the homeowner plans on using it for themselves.
