Steve discusses what the best deal for you and your long-term goals. The base question should be what are the long term effects of this purchase. Remember, buying a home is a business transaction, and you need to have a goal.
As Steven Covey would say “begin with the end in mind.” What is the end game? What is your business plan (even if you are buying your primary residence)?
As you would with anything, you should take the time to learn how to care for your investment.
