You should look at paying off other NON tax deductible debt (i.e. credit cards, collections, etc), look at where you are with retirement savings, are you in a position to increase your wealth by purchasing more property vs. sinking money into dead equity, etc.
There are a lot of factors, but without knowing your C.L.A.D. its hard to advise.
Contact me and within minutes of asking you a few questions I can likely give you better advice than most can give.
