Sibling Keeping all the Profits !!!

What is the name of your state?
Pennsylvania

I am submitting a question, to find out if I have any legal recourse or not. It is my feeling that I probably do not,but
felt it was worth trying to find out for sure.
My situation is as follows:
My mother passed away some 6+ years ago. Her home was left to myself and my sibling.Before she passed during her illness, it was verbally agreed that my sibling would get Mothers home, and I would get the siblings condo, valued at
half the value of Mother's home.So I have the condo,all free and clear. At the time a fair deal.
Today, 6+ years later, my sibling is selling Mom's home
to buy another. However the property is not being sold
for market vlue. A company looking to buy up property,
is purchasing the property, for $125,000 more than the market value of the house.
My sibling is financially secure, I on the other hand am
struggling greatly financially, There has been no offer to
give me any of the profits he is making on our Mother's home. Am I legally entitled to anything?

Signed,
Deeply Hurt and Stressed
