Clark recently received an offer in his mailbox to get a mortgage on his house for 1.5 percent interest! It's like 2004 all over again when the weirdo loans were rampant. It turns out this is a new trend among mortgage companies. Lenders have seen the volume of business fall so much that they're getting increasingly desperate -- hence a slew of mailings trying to get you to treat your house like an ATM. Clark received a mailing from Countrywide offering $511,000 for a refinance. Meanwhile, The Los Angeles Times reports that lenders are also sending out mailings about option payment loans again. These are the kind where the balance rises over time instead of declining. What is going on here? When Clark looked closely at the first offer, he saw it was a teaser rate that's only good for 90 days. So beware that these mailbox offers can financially blow up in your face. Remember there is no free lunch. Clark wants you to learn in his school, rather than the school of hard knocks.
