Purchasing off market via executor of the will - Ran into roadblock.. - Path forward?

[Jim Doyle]

I'm looking to purchase an off-market home in my neighborhood and ran into a hurdle that I might not be able to overcome...For context my elderly neighbor who I've been friends with for the last couple of years recently passed away. His sister is the executor of his will and is staying at his home to fulfill all of the end of life obligations that he has. We discussed me purchasing the home and had verbally agreed to sell the house to me. I know that a verbal agreement doesn’t mean much so I was looking to get her into a purchase contract.

The sister visited her brother's lawyer to discuss the responsibilities of being executor of the will and what needs to be done in order to sell the house. She found out from her brother’s lawyer that he has put the house into a trust and that the decision of what happens to the house is up to the trustees. If that is the case, does the executor of the will, in this case his sister have any influence on whom the trustees sell the house too? Is there anything I can do to ideally get them to not list the house and sell to me, I’m assuming there might not be many options, especially since the sister and I had agreed on a price that was below market value given I was planning to invest money to remodel the home and was planning to honor his wishes of not having the home knocked down to make a townhome or new home. I think it's a long shot, but looking for any possible ideas...
