Right Of First Refusal. Is It a Guarantee?

[William Coet]

Hello,

I would like to offer a woman a payment for a Right of First Refusal on her home.  I am wondering what can go wrong and if there are ways to guarantee it will work.  I am considering offering the RoFR because I do not think she would sell the house now.

For example:  1. What if she has granted the property to someone else in her will?

2. What if she goes into a nursing home and the nursing home places a lien on the property?

3.  Etc., etc.,

Is there a way to avoid problems like this?

Thank you!
