This is, again, another relationship building exercise.

You're actually exercising admirable restraint.

The IRS looks at the substance and would ask "do you exercise the power of officer or director"; if one exercises such power, they are an "officer or director", regardless of what the paperwork says.That this is "just in the House and has not passed yet" is no reason for complacency. 

That's because there are no tax consequences to the grantor until the option lapses or is exercised.If the option lapses (that is, the holder chooses not to buy the real estate), the grantor has income equal to the amount paid to him or her for the option.If the option is exercised by the holder (that is, the holder buys the real estate), the sale proceeds for purposes of determining the grantor's gain or loss on the sale of the real property includes the amount the grantor received for the option.The grantor's tax deferral can only be achieved if the agreement is a true option. 

I went through the same exercise 15 years ago and knowing what I know now may be able to help you narrow down your search.

This is something they have the ability to do, but many don't regularly exercise it.

You will not receive that money until your buyer exercises their option to purchase.

I would still exercise my right as the buyer to have my own inspection done.

including entry to exercise a contractual or statutory lien?

Exercise patience.
