Arm loans can be a great option for homebuyers who want flexibility in their mortgage payments. With an arm loan, the interest rate can change periodically, which can save you money on your monthly payments.
There are several types of arm loans, including the 5/1 arm, which has a fixed interest rate for the first five years and then adjusts annually. This type of loan can be a good choice for people who plan to move or refinance their home within a few years.
The 7/1 arm is another popular option, with a fixed rate for the first seven years and then annual adjustments. This loan can be a good fit for people who want to take advantage of lower interest rates in the short-term.
One of the main benefits of arm loans is that they often have lower interest rates than fixed-rate loans, which can save you money on your monthly payments.
Understanding ARM Loans
ARM loans can be complex, but understanding their basics is key to making an informed decision.
The most common type of ARM loan is the 5/1 ARM, which means the interest rate is fixed for the first five years and then adjusts annually.
A 5/1 ARM can save you thousands of dollars in interest over the life of the loan, but it's essential to consider the potential for higher payments later on.
ARM loans often have a cap on how much the interest rate can increase, which is usually around 5-6% above the initial rate.
The initial interest rate on a 5/1 ARM is typically lower than a fixed-rate loan, which can make it more attractive to borrowers.
However, if you plan to stay in your home for a long time, a fixed-rate loan might be a better option, even with a slightly higher interest rate.
ARM loans can be a good choice for people who expect to move or refinance within a few years, but it's crucial to review the terms carefully.
Types of ARM Loans
ARM loans come in two main formats: interest-only loans and adjustable-rate mortgages (ARMs). Interest-only loans allow you to pay only the interest on the loan for a set number of years, after which your monthly payment starts to include principal.
These loans are often structured in the format of "5/6", with the 5 being the number of years you'd pay only interest and the 6 indicating that your rate will be adjusted every 6 months. Most interest-only loans are ARMs, meaning your interest rate on the loan will be adjusted some number of times each year based on the current rates.
ARMs have a fixed period and an adjusted period. The fixed period is the time during which the interest rate doesn't change, typically ranging from 5 to 10 years. The adjusted period is when the rate changes based on market conditions.
Here are some common types of ARM loans:
- 5/6 ARM: 5 years of interest-only payments, then rate adjusted every 6 months
- 7/1 ARM: 7 years of fixed payments, then rate adjusted annually
- 10/6 ARM: 10 years of fixed payments, then rate adjusted every 6 months
ARMs can be more expensive long-term, so it's essential to consider your financial situation and goals before choosing an ARM loan.
Types of ARM Loans
An ARM loan can be a smart financial choice for homebuyers who plan to keep the loan for a limited period of time and can afford any potential increases in their interest rate.
ARM loans come in various forms, including 3/1, 5/1, 7/1, and 10/1 ARMs. These numbers represent the length of the fixed-rate period and the frequency at which the interest rate changes following the fixed-rate period.
The 5/1 ARM is a popular option, with a national average interest rate of 6.53% and an APR of 7.14%. This means that for the first 5 years, the interest rate will remain fixed, and then it will adjust annually based on market conditions.
Here are some key characteristics of different ARM loan options:
During the introductory period, ARM rates are typically lower than their fixed-rate counterparts. For example, the 5/1 ARM rate is lower than the 30-year fixed rate, which is 7.00%.
Fixed vs. Flexible
If you're considering an adjustable-rate mortgage, you'll want to think about the difference between fixed and flexible payments. A fixed-rate mortgage has the same interest rate for the life of the loan, never changing.
With a fixed-rate mortgage, your mortgage payment will be the same amount every month. This can be a big advantage if you like knowing exactly how much you'll be paying each month.
An adjustable-rate mortgage, on the other hand, has a fixed rate for a set time before being adjusted throughout the remainder of the loan. This means your loan amount may vary, depending on the ARM option, every 6 months or annually.
In an adjustable-rate period, the interest rate changes, which can impact your loan amount. This can be a risk if you're not prepared for potential changes in your payment.
Types of ARM Loans
Interest-only loans are a type of ARM that allow you to pay only interest on the loan for a set number of years, typically 5-10 years. This can be a great way to lower your monthly payments in the short-term, but be aware that your payments will increase when the interest-only period ends.
Interest-only loans are often structured as "5/6" loans, where the 5 represents the number of years you pay only interest and the 6 indicates that your rate will be adjusted every 6 months.
Most interest-only loans are ARMs, which means your interest rate will be adjusted periodically based on market conditions. This can be a good option if you're planning to keep the loan for a limited time and can afford any potential increases in your interest rate.
There are two main types of interest-only ARMs: 5/6 loans and interest-only fixed-rate mortgages. However, interest-only fixed-rate mortgages are very rare.
Here's a summary of the key characteristics of interest-only loans:
Interest-only loans can be a smart financial choice for homebuyers who want to lower their monthly payments in the short-term, but it's essential to consider the potential risks and costs of these loans.
ARM Loan Characteristics
ARM loans can be more complex than fixed-rate loans, but understanding their characteristics can help you make an informed decision.
Most interest-only loans are ARMs, which means your interest rate on the loan will be adjusted some number of times each year based on the current rates, causing your monthly payments to go up or down.
These loans are often structured in the format of “5/6,” with the 5 being the number of years you’d pay only interest and the 6 indicating that your rate will be adjusted every 6 months.
ARMs can be more expensive long-term, so if a rate that is guaranteed not to increase sounds better to you, you may instead want to refinance to a conventional fixed-rate loan.
Here are the standard conventional Fannie Mae ARM requirements:
To determine whether an ARM loan is acceptable for purchase by Fannie Mae, lenders must subtract the initial note rate of the loan from the fully indexed rate in effect when the loan was originated. The difference must not exceed 3%.
Balloon Loans
Balloon Loans can be a good idea for homeowners who know they won't be in a house very long.
You'll have low monthly payments, which can be a big advantage if you need to use your money for other things, such as building credit or savings.
A balloon loan is a mortgage that operates on a lump-sum payment schedule, where you'll pay the remainder of the balance at once at the end of the loan.
This can be a combination of interest and principal, with a somewhat smaller lump-sum payment at the end, depending on your lender.
You may pay only interest for the life of your loan and make one big principal payment at the end, which can be a relief if you're on a tight budget.
With a balloon loan, you'll have more flexibility to use your money for other things before making your eventual lump-sum payment.
Acceptable Characteristics
When considering an ARM loan, it's essential to understand the acceptable characteristics. Here are some key facts to keep in mind:
Fannie Mae doesn't set a minimum remaining term requirement at the time of loan purchase. This means lenders have some flexibility when it comes to the loan's term.
The initial adjustment period in months must align with the initial fixed-rate period in years. For example, a "3-year ARM" must have an initial fixed period of 36 months, and a "5-year ARM" must be 60 months.
Each ARM plan must offer lifetime and per-adjustment interest rate change limitations. This helps protect borrowers from extreme rate changes.
Mortgage interest rates may never decrease to less than the ARM's margin, regardless of any downward interest rate cap. This ensures that the interest rate will always be a minimum amount.
Fannie Mae restricts purchase or securitization of seasoned ARMs to those that are delivered as negotiated transactions. This means lenders must follow specific guidelines when selling these loans.
Loan-Level Price Adjustments
Loan-Level Price Adjustments (LLPAs) apply to certain ARM loans. These adjustments are in addition to any other price adjustments that are otherwise applicable to the transaction.
Fannie Mae has a Loan-Level Price Adjustment Matrix that outlines the specific LLPAs. The LLPAs are referenced in recent Announcements, including Announcement SEL-2022-10, dated December 14, 2022.
An LLPA applies to certain ARM loans, and it's essential to check the Loan-Level Price Adjustment Matrix for the most up-to-date information.
Margin
The margin is a crucial component of an ARM loan. It's the "spread" that's added to the index value to develop the interest accrual rate for the mortgage.
The maximum mortgage margin may be no more than 300 basis points. This is a significant factor in determining the interest rate of your ARM loan.
In some cases, the margin is not used in determining the initial interest rate, but it will be used to determine the interest rate for all future interest rate changes. This is often the case when lenders offer a deeply discounted "teaser" rate for the mortgage.
Here's a breakdown of how the margin affects your ARM loan:
This means that while the margin may not impact your initial interest rate, it will play a significant role in determining your interest rate as your fixed rate period expires and your loan becomes adjustable.
Fixed-Interest
Fixed-Interest Mortgages offer a predictable and stable option for homeowners.
They generally have higher interest rates at the outset than ARMs, but this can make ARMs more attractive and affordable in the short term.
With a fixed-rate mortgage, monthly payments remain the same.
The amounts that go to pay interest or principal will change over time, according to the loan's amortization schedule.
If interest rates in general fall, then homeowners with fixed-rate mortgages can refinance, paying off their old loan with one at a new, lower rate.
This provides a safety net for homeowners, protecting them from rising interest rates.
Disclosures
Disclosures are a crucial part of the ARM loan process, and lenders are required to provide borrowers with specific information to ensure they understand the terms of their loan.
Lenders must provide borrowers with disclosures in compliance with all applicable laws, as stated in ARM Disclosures. This means borrowers can expect to receive clear and accurate information about their loan.
When your initial interest rate is below-market, lenders must notify you of current index values and mortgage margins. They'll also show you an example of what your interest rate would be if the loan had been adjusted at the time of origination.
This is to prepare you for the possibility of an interest rate increase and a payment increase on the first interest rate adjustment date. It's essential to review this information carefully to understand your loan's terms.
Disclosures regarding conversions must include specific details, such as:
It's essential to carefully review these disclosures to understand your loan's terms and any requirements for conversion.
ARM Loan Calculations
ARM loan calculations can be a bit tricky, but understanding the basics can help you make informed decisions.
The fully indexed rate is the sum of the applicable index and the mortgage margin, rounded to the nearest one-eighth percent.
Unless specific product terms provide otherwise, if the index plus gross margin equals a number that is equidistant between the higher and lower one-eighth percent, Fannie Mae rounds down to the nearest one-eighth percent.
The applicable index value that determines the fully indexed rate is any index value in effect during the 90 days that precede the note date.
Interest accrual rate calculations are based on the mortgage margin added to the most recent index figure available 45 days before the interest change date, rounded to the nearest one-eighth percent.
Here's a quick rundown of the ARM loan calculations:
Fully Indexed Calculation
The fully indexed rate is the sum of the value of the applicable index and the mortgage margin, which is then rounded to the nearest one-eighth percent.
Unless specific product terms provide otherwise, the fully indexed rate is rounded down to the nearest one-eighth percent if the index plus gross margin equals a number that is equidistant between the higher and lower one-eighth percent.
The applicable index value that determines the fully indexed rate is any index value in effect during the 90 days that precede the note date.
This means you need to look at the index values from the past three months to determine the fully indexed rate.
Interest Accrual Calculation
Interest accrual rates for ARM loans are calculated by adding the mortgage margin to the most recent index figure available 45 days before the interest change date.
For standard ARM plans, Fannie Mae instruments round interest rate calculations to the nearest one-eighth.
If a mortgage instrument provides otherwise, lenders must check with their Fannie Mae customer account team to ensure there are no pooling and/or disclosure impacts.
Interest rate calculations are subject to applicable per-adjustment and lifetime interest rate change limitations.
How to Get the Best Results
To get the best results with an ARM loan, it's essential to strengthen your finances. This means checking your credit score and working to improve it, aiming for a "very good" score at least. A better credit score can lead to a more favorable interest rate.
Having a good handle on your budget is also crucial. You should use an adjustable-rate calculator to estimate how your mortgage payment could change once the rate adjusts. This will help you determine how much house you can afford.
Comparing different types of ARMs is also important. Consider options like 5/1, 5/6, 7/1, and 10/1 ARMs, and think about the tradeoff between introductory rates and fixed-rate periods.
To find the best ARM offer, rate-shop with at least three different lenders. Make sure to compare interest rates, fees, and rate cap structures. This will help you understand the fine print and make an informed decision.
ARM Loan Plans
ARM Loan Plans can be tied to the Secured Overnight Financing Rate (SOFR) Index, which is a broad measure of the cost of borrowing cash overnight collateralized by U. S. Treasury securities in the repurchase agreement market.
Fannie Mae uses a 30-day average of the SOFR index as published by the Federal Reserve Bank of New York. A Fannie Mae ARM plan must be tied to this index.
To qualify as a Fannie Mae standard conventional ARM, the ARM must meet all of the characteristics specified in the Standard ARM Plan Matrix. This matrix is available on Fannie Mae's website and is incorporated by reference into Fannie Mae's guide.
Here are some key characteristics of Fannie Mae standard conventional ARMs:
Generic ARM plans are also available for loan casefiles underwritten through DU, and can be used to assist lenders in underwriting negotiated ARMs and standard ARM plans that are not specifically identified in the ARM plan field in the DO/DU user interface.
Standard Conventional Plans
Standard conventional ARM plans must meet specific requirements to qualify. These plans are outlined in the Standard ARM Plan Matrix, which is available on Fannie Mae's website.
To qualify, a conventional ARM plan must have a monthly payment due on the first day of the month. This ensures that borrowers make timely payments and don't fall behind on their mortgage.
An original maturity of no longer than 30 years is also required for standard conventional ARM plans. This means that the loan will be fully paid off within 30 years, providing a clear repayment schedule for borrowers.
To be pooled as a standard Fannie Mae ARM plan without a special disclosure, a plan must meet all of the standard plan characteristics and meet three additional requirements. These requirements are:
- Have a monthly payment that is due on the first day of the month;
- Have an original maturity no longer than 30 years; and
- Be originated on the applicable Fannie Mae standard forms, with no modifications, which cover all other pooling requirements.
By meeting these requirements, standard conventional ARM plans can be pooled and sold on the secondary market, providing liquidity for lenders and borrowers alike.
DU Generic Plans
DU Generic ARM Plans are available as tools for underwriting with DU, and to assist lenders in underwriting negotiated ARMs and standard ARM plans that are not specifically identified in the ARM plan field in the DO/DU user interface.
These generic ARM plans are listed in the DO/DU user interface, including FM GENERIC, 1 YR, 1% ANNUAL Cap and FM GENERIC, 1 YR, 2% ANNUAL Cap.
The term in these generic plans refers to the initial fixed-rate period, which is a key detail to keep in mind when working with these plans.
Here are the generic ARM plans available in the DO/DU user interface:
- FM GENERIC, 1 YR, 1% ANNUAL Cap
- FM GENERIC, 1 YR, 2% ANNUAL Cap
- FM GENERIC, 3 YR
- FM-GENERIC, 5 YR
- FM-GENERIC, 7 YR
- FM-GENERIC, 10 YR
Note that generic plan names are only used to submit loan casefiles to DU, and lenders must identify the applicable Fannie Mae ARM plan number in closing documents and at delivery of the loan to Fannie Mae.
