What Is a Growing Equity Mortgage (GEM)?
A Growing Equity Mortgage (GEM) is a type of mortgage where the borrower's monthly payments are designed to increase over a specified period, with the entire increase applied directly to the loan's principal. Unlike other mortgage structures that might have fluctuating payments due to changing interest rates, the payment growth in a GEM is predetermined and intended to accelerate the reduction of the loan balance. This mortgage product falls under the broader category of real estate finance and is structured to help homeowners build equity at a faster pace and pay off their loan sooner than with a traditional fixed-rate mortgage.
History and Origin
The concept of the Growing Equity Mortgage emerged in the early 1980s, a period characterized by high inflation and elevated interest rates, which made traditional homeownership less accessible for many prospective buyers. Faced with these economic challenges, financial institutions sought innovative solutions to help consumers afford homes. The Federal National Mortgage Association (Fannie Mae) introduced GEMs as a response to this environment, aiming to provide a financing option that could accelerate loan repayment. The Federal Register noted in early 1983 that the Federal Housing Administration (FHA) was looking to expand its program to include Growing Equity Mortgages (GEMs), alongside Graduated Payment Mortgage-Backed Securities.5 Such innovative financing arrangements, including GEMs and adjustable-rate mortgages, became more common in the volatile interest rate environment of the 1970s and 1980s.4
Key Takeaways
- Growing Equity Mortgages (GEMs) feature monthly payments that incrementally increase, with all the additional payment amount directed towards the loan's principal.
- The primary benefit of a GEM is the accelerated payoff of the loan and a substantial reduction in the total interest paid over the life of the mortgage.
- GEMs are typically suited for borrowers who anticipate a steady increase in their income over time.
- While offering faster equity build-up, GEMs require borrowers to be comfortable with steadily rising monthly payment obligations.
Interpreting the GEM
A Growing Equity Mortgage fundamentally alters the traditional amortization schedule by systematically increasing the portion of each payment that goes toward the principal. This means that early in the loan term, as payments rise, more of that increase is applied to the principal balance than would be with a static payment, leading to a quicker reduction of the total debt. This rapid principal reduction means the borrower accrues equity in their home at an accelerated rate. For instance, if a borrower has a 30-year GEM, the increasing payments could result in the mortgage being paid off in 15 years or less, significantly shortening the borrowing period.
Hypothetical Example
Imagine a homeowner, Sarah, takes out a $300,000 Growing Equity Mortgage with an initial annual interest rate of 5%. Instead of fixed payments, her mortgage agreement stipulates that her monthly payment will increase by 2% each year.
In the first year, Sarah's initial monthly payment might be similar to a traditional 30-year fixed-rate mortgage. However, starting in the second year, her monthly payment would increase by 2%. This additional amount, rather than being adjusted for interest, is entirely applied to the principal balance. This process repeats each year.
- Year 1: Monthly Payment X (standard principal and interest)
- Year 2: Monthly Payment X + (2% of Month 1 Payment)
- Year 3: Monthly Payment (from Year 2) + (2% of Month 1 Payment)
(This simplification illustrates the concept; actual calculations would be more complex and apply the increase to the prior year's payment or a base payment).
Over time, this consistent increase in principal payments allows Sarah to pay down her $300,000 loan significantly faster, potentially cutting years off the original 30-year loan term and saving her a considerable amount in total interest costs.
Practical Applications
Growing Equity Mortgages (GEMs) are particularly relevant for individuals or families who anticipate consistent and reliable growth in their income over time. This might include young professionals, individuals on a clear career progression path, or those expecting significant salary increases. By locking in a payment increase schedule, borrowers can align their rising income with an accelerated debt reduction strategy for their home.
These mortgages provide a disciplined approach to building home equity faster, which can be advantageous in several ways, such as enabling a borrower to sell their home with more equity earlier, or to reduce their overall debt burden. While less common than conventional loans or adjustable-rate mortgages, GEMs can be a strategic choice for borrowers who prioritize rapid debt repayment and interest savings. The Freddie Mac House Price Index (FMHPI®), for example, provides a measure of typical price inflation for houses, which can influence a homeowner's overall home equity position. 3Insights from entities like the Consumer Financial Protection Bureau (CFPB) often highlight various types of mortgage loans and their implications for consumers, helping them understand their options.

Limitations and Criticisms
Despite their advantages, Growing Equity Mortgages come with specific limitations and criticisms. The most significant concern for borrowers is the commitment to steadily increasing monthly payments. If a borrower's anticipated income growth does not materialize, or if unforeseen financial challenges arise (e.g., job loss, medical expenses), the escalating payments of a GEM could become unsustainable, potentially leading to financial strain or even default risk. This contrasts with fixed-rate mortgages, which offer predictable payments, or even some adjustable-rate mortgages that might see payment decreases if market rates fall. The Federal Reserve Bank of Kansas City, in a review of financial flexibility during inflationary periods, noted various alternative financing arrangements, highlighting the need for borrowers to carefully consider the implications of increasing payments. 1Unlike some mortgage types where interest payment might lead to negative amortization if not structured correctly, a GEM's increasing payments are designed to prevent this by directly targeting principal reduction.
GEM vs. Graduated Payment Mortgage (GPM)
Growing Equity Mortgages (GEMs) are often confused with Graduated Payment Mortgages (GPMs) due to their shared characteristic of initially lower, then increasing, monthly payments. However, a crucial distinction separates them:
| Feature | Growing Equity Mortgage (GEM) | Graduated Payment Mortgage (GPM) |
|---|---|---|
| Payment Increase | The entire increase in monthly payment is applied to the principal. | The increase covers rising interest accrual, with any excess going to principal. |
| Amortization | Accelerates principal payoff, significantly shortening the loan term. | Often designed to prevent negative amortization in early years; may not significantly shorten the loan term beyond the original schedule. |
| Total Interest | Substantially reduces the total interest paid over the life of the loan. | May result in more total interest paid compared to a traditional fixed-rate mortgage, especially if initial payments lead to negative amortization. |
| Goal | Rapid equity accumulation and faster debt payoff. | Lower initial payments to make homeownership more accessible, with payments gradually rising. |
While both start with lower payments and see them rise, the fundamental difference lies in where the increased payment goes. A GEM is designed to pay down the principal faster, whereas a GPM's initial increases primarily cover the interest that was deferred or slowly accruing, and sometimes only later begin to significantly reduce principal.
FAQs
How does a Growing Equity Mortgage differ from a traditional fixed-rate mortgage?
A traditional fixed-rate mortgage has consistent monthly principal and interest payments for the entire loan term. In contrast, a Growing Equity Mortgage (GEM) has payments that are predetermined to increase over time, with all the additional money going directly towards reducing the loan's principal, leading to a faster payoff.
Who is a Growing Equity Mortgage best suited for?
A GEM is typically best suited for borrowers who are confident their income will consistently increase over the life of the loan. This allows them to comfortably manage the escalating monthly payments and take advantage of the accelerated equity build-up and interest savings.
Can the payments on a GEM decrease?
No, the payments on a Growing Equity Mortgage are designed to increase at a predetermined rate. Unlike an adjustable-rate mortgage where payments can fluctuate based on market interest rates, a GEM's payment schedule is fixed to grow.
Do I pay less total interest with a GEM?
Yes, because the increasing payments in a Growing Equity Mortgage are applied directly to the loan's principal, the overall balance is reduced much faster. This means less interest accrues over the life of the loan, resulting in significant savings compared to a standard 30-year fixed-rate mortgage.
Is a down payment required for a Growing Equity Mortgage?
As with most mortgage types, a down payment is typically required for a Growing Equity Mortgage. The specific requirements would depend on the lender and the borrower's financial profile.
