Need advice on a potential purchase or not...

[Sam Leon]

I normally look for investment properties but recently I was intrigued by a FSBO property as a primary home, not as a rental.

The owner is hesitant and not even sure he wants to sell, or if he sells, when.  It is priced reasonably.

What is the best way to approach this?  If a purchase contract is not possible at this moment, are there other ways to at least have some sort of an agreement in the event he decides to sell in the future, some sort of a "Buyer's right of first refusal to purchase" for a set price and duration that may work to my advantage and still give the seller the freedom to not sell?

Pros and cons?
