At our locked in rate we currently owe $1200 a month exactly on our mortgage. Instead we pay $1360 a month. Does that little bit extra help or should I be putting more onto it? Trying to decide how much to pay on mortgage verses how much to put aside for renos. As we are locked in we can not access the extra money on our mortgage (which would be approx $4,000 at current) but we can defer our mortgage payments while we are in front.
