Discharging Existing Mortgage
Many people when selling their home, use the proceeds from the sale to "discharge" or pay off their mortgage loan. If you are fully "open" mortgage, you can discharge it at any time without penalty. However, if yours is a fully "closed" mortgage, discharging it may require you pay substantial penalties, often in the amount equal to several months' interest payments.
There are ways to avoid these penalties, such as taking a "portable" mortgage with you when you sell your present home and applying it to the home you buy. Depending on your specific sales objectives, you may be able to time the sale's completion to coincide with the end of the mortgage term.
A portable mortgage allows you to take your mortgage with you (without penalty) if you sell your present home and buy another one, usually within a specific period of time. This can be very beneficial, particularly if the interest rate on your mortgage is lower than the market rates at the time of your move. If your new home requires a larger mortgage amount, the additional funds required can usually be borrowed at the current market rate. Portability can also enable you to avoid substantial penalties in discharging a closed mortgage when you sell your home.
If you are planning to buy your next home before the sale of your current home is complete, you may want to consider "bridge financing". Broadly speaking, bridge financing enables you to borrow an amount equal to (or less than) the net proceeds you are expecting to realize on your sale - and to use these borrowed funds to purchase your next home. When the sale of your current home closes, you use the proceeds to pay off the short-term bridge loan plus interest.
