Re: Three Owners, Two Want to Sell to Third Owner
You can have a contract drawn up by a real estate attorney. Liability for the mortgage, depends on who is listed on the mortgage. In general, unless your brother is solely listed on the mortgage, he will need to get another one and pay off this one, unless other listed people agree to continuity of liability. If he cannot swing the deal and refuses to sell to another person, you will need a court order, forcing the sale of the property, unless you can find a buyer willing to only buy your interest.
Teach a man to fish, you feed an entire village. Give a man a fish, the village starts demanding free fish. Then they have three children who all start families and demand free fish as their right.
