More information will be needed. Are you trying to buy off the remainder of a loan on your own home? If so, you need to speak with your lender before you try to do this - many banks do not allow customers to finalize a loan before the end of the terms. Others charge high fees to pay off a loan early.
Are you trying to "buy out" the remainder of another person's loan? Is this through the homeowner or a bank? If it is through a bank, keep in mind that banks usually look for fair market value when selling a home - this number may be more or less than what is owed on a property.
If you want to discuss this further, you can reach me at directly at 203-815-9118. I'm a full time agent in the area and help many people buy and sell homes.
