Engineering Your Way Out of PMI
Finding the right way to buy a home often feels like a complicated science experiment. You want a low monthly payment, but you also want to keep as much of your savings as possible. This brings many buyers to ask one important question: What is a piggyback mortgage? Simply put, a piggyback mortgage is a strategy where you take out two separate loans at the same time to buy one home. This technical setup allows you to buy a house with a smaller down payment while avoiding the extra cost of insurance. By using this formula, you can often reach the magic 20% equity mark without actually having all that cash on hand. This article will help you determine if this should be a strategic part of your California Homeownership Formula.
How the 80/10/10 Formula Works
The most common version of this setup is known as the 80/10/10 loan. In this scenario, your financing is broken down into three distinct parts. First, you get a primary mortgage that covers 80% of the home’s price. Because this loan stays at exactly 80%, you do not have to pay for private mortgage insurance (PMI).
Specifically, you take out a second mortgage to cover the next 10% of the price. This loan “piggybacks” on top of the first one, which is where the name comes from. Finally, you provide the last 10% as your cash down payment. Consequently, when you add these pieces together, you have 100% of the funding you need to close the deal.
Why Choose Two Loans Instead of One?
You might wonder why anyone would want the hassle of two different monthly bills. The main reason is the monthly savings. Private mortgage insurance (PMI) is a monthly fee that protects the bank, but it provides no benefit to you as the homeowner. As a result, many buyers would rather pay interest on a small second mortgage than pay for insurance they will never see again.
Example of a regular Conventional Mortgage vs a Piggyback:
|
Scenario |
90% Loan with PMI |
80/10/10 Piggyback |
|---|---|---|
|
First Mortgage |
$450,000 (at 6.5%) |
$400,000 (at 6.5%) |
|
Second Mortgage |
None |
$50,000 (at 8.5%) |
|
Monthly PMI |
~$350/mo |
$0 |
|
Monthly Total |
Higher |
Lower (usually) |
Furthermore, a piggyback mortgage can help you avoid “jumbo” loan territory. In expensive areas like California, home prices often exceed standard loan limits. By splitting the debt into two loans, you might keep your main loan small enough to qualify for better interest rates. However, you should remember that you will likely have two sets of closing costs to cover at the start.
Is This Strategy Right for Your Lab?
At The Funding Lab, we believe every home purchase needs a custom formula. For many of our First-Time Homebuyers, the piggyback mortgage is the bridge that lets them buy a home years sooner than if they waited to save a full 20% down payment. We provide the technical data you need to compare the cost of PMI against the cost of a second loan.
While this maneuver is powerful, it does require a bit more paperwork. You must qualify for both loans at the same time. This means your income and credit history will be under a microscope. If your variables are strong, though, the savings can be significant over the life of your homeownership.
Conclusion
Understanding “what is a piggyback mortgage?” gives you a massive advantage in today’s market. It is a tool designed for flexibility and long-term savings. If you are tired of the idea of paying for mortgage insurance, it might be time to look at a multi-loan strategy instead.
