Combination Loan

A borrower purchasing a home might obtain a first mortgage and a second mortgage at the same closing. The two loans cover different portions of the price, while the buyer supplies the remaining down payment.

An 80-10-10 example has a first loan for 80% of price, a second for 10% and a 10% cash down payment, though these numbers describe one structure and not a mandatory standard. The second loan may be a home equity loan or line of credit.

The CFPB calls a simultaneous second mortgage a piggyback loan and notes it may be marketed as an alternative to private mortgage insurance. Mortgage insurance protects the lender against certain default losses, not the borrower against unaffordable payments, and the borrower generally pays for it when required under the chosen loan program.

A piggyback arrangement can reduce or avoid the mortgage-insurance charge on a qualifying first mortgage, but the second loan adds interest, fees and possibly a variable rate. Two loans mean two obligations, so the borrower should compare both payment schedules and understand whether the second loan's balance can rise, reset or become due under different terms.

Closing costs may also differ, and a shared lender does not make two loans equivalent to one low-cost closing, because actual lender quotes and disclosures control. Refinancing can be more complicated because the second lienholder may need to agree to the new first mortgage's priority, a possible hurdle the CFPB specifically flags.

In a construction setting, financing may pay for building first and then transition to a longer-term mortgage, and contract details determine whether there are two closings, one closing or a replacement loan. The everyday label combination loan is therefore less precise than the signed documents, so a borrower should identify whether two mortgages coexist or one loan replaces another after construction.

Compare alternatives over a realistic holding period, because if the home may be sold or refinanced soon, upfront costs can matter more than a small later difference in monthly payments. A second loan can make the initial cash down payment smaller, but it also raises total borrowed principal, which can amplify the household's exposure if property value falls.

The first mortgage's quoted rate alone cannot measure the whole financing cost, so add second-loan interest, mortgage insurance where applicable, points, fees and expected changes in variable rates. An 80% first-loan-to-value ratio does not mean the homeowner has 20% equity if a second mortgage finances part of that difference, and combined debt is the relevant measure of household leverage.

A useful decision compares written quotes for a single mortgage with insurance and the proposed combination, including downside scenarios. The goal is affordable total borrowing, not simply avoiding one fee.
