Bridge financing, hybrid loans take stress out of equation. Buying a first home is hardly easy, but it pales in comparison to buying your next home. Usually, two transactions are involved: the purchase of the new home and the sale of your current home. In other words, double the complexity.

However, stringent lender qualifying requirements make it impossible for most buyers to buy before selling.
