To answer this question, there are many more facts that I would need to know in order to answer your question more throughly. Your children might want to consider hiring an attorney to seek an accounting of your sister as trustee as to where the money that was placed in the trust for the upkeep of the property has gone. She money left in the trust, ie. $10,000, belongs to your children and not the trustee so she can not offer to "buy" the house for the money left in the trust because this money already belongs to them.
