you say that if you sell your house you may get 100k. You are earning 7k gross on this 100k asset. Not bad- few of us are getting 7% gross return on the present value of our property. Based only on that information I'd hold on to the property. But we need to know more facts.
The usual advice is that if you can pay off a loan with a lump sum then do so, but without knowing other facts - your other income, the type of loan deal you have etc , it's unwise for anyone to be too specific with advice.
