Do You Know the Pros and Cons of a Interest Only Mortgage?

Has any lender ever told you the Interest Only Mortgage was like a double-edged sword? It can help you achieve your dream of owning a home more easily, but it also can create a financial hardship for those who don’t fully understand what’s involved.

Interest Only Mortgage has become more popular to new homebuyers for the following reasons:

  • Since the monthly payment is low, the savings can be used for personal spending, paying off higher interest debts, buying furniture for the new house, or even investing.
  • The interest paid to the Interest Only Mortgage is still eligible for tax write-off at the end of the year.
  • Some Interest Only Mortgages allow you to make a principal payment during the interest only period. This helps reduce your balance the following month which lowers your payment further.

However, Interest Only Mortgage is not for everyone:

  • Beware a potential prepayment penalty for the first 1-3 years imposed by some lenders.
  • You have to play the “catch up game” once you begin to pay the principal. The amount is much more since you didn’t pay during the interest only payment years.
  • Think twice before committing to an Interest Only Mortgage if it’s the only way for you to afford a house.
