My mother has been paying the taxes and home owners policy for the last 6 years for our shore house. My sister and I have been paying the taxes and home owners insurance (for the last year and half) since my brother bought a house of his on 2 years ago and doesn't use the family shore house.
We want to buy him out but - should we buy him out at the value of the house 6 year ago or current value?
EDIT: The deed is in all three siblings names. Mom has paid the taxes and home owners insurance for 6 years, and then my sister and I payed them for the last year and a half.
