A friend of mine is going through divorce but wants to keep the house

[Luka Milicevic]

Hey BP,

I have a good friend of mine who is currently going through a divorce. 

He has two options with the house

1-sell and split the proceeds

2-Keep the house and payout his spouses equity portion over the next 10 years

He wants to keep the house as he has a low interest rate that he will never be able to get again. 

One of the suggestions was to assume the loan to get her off the mortgage, but the lender said that he is "pretty sure" that mortgage assumptions are only possible when someone is purchasing the property.

My question is, are there scenarios or suggestions for keeping the house and existing loan and not having to refinance to get her off the loan?
