Adjustable Rate Mortgage

An adjustable rate mortgage (ARM) may help you save money in the short term. Generally, an ARM has lower monthly principal and interest payments during the initial fixed interest rate period.1 Later, your interest rate will be variable and will adjust annually if the index changes. An ARM may be the best way to go if you don't plan to live in your home for a long time.

  • Your monthly principal and interest payment may be less during the initial fixed interest rate period for an ARM versus a fixed rate mortgage
  • Your initial interest rate is fixed for a short period of time1, after which it will convert to a variable rate and adjust annually during the life of your loan if the index changes
  • Once the loan converts to a variable rate, interest rates and payments may vary

Under what circumstances would an adjustable rate mortgage (ARM) be a better choice than a fixed rate loan?

If you expect to stay in your home for a relatively short period of time, consider an Adjustable Rate Mortgage (ARM). You can potentially save a significant amount with a lower interest rate and lower monthly payments in the short term. ARM interest rates may rise, however, after an initial fixed period. Consult with a BMO Harris Mortgage Banker for more information.

What is the difference between prequalification and preapproval?

Prequalification is a quick analysis of how much loan you can afford based on verbal information you provide to us. It will give you a general idea of the price range you can afford. There are no fees for a BMO Harris prequalification.

Preapproval is a loan commitment based on verified information prior to finding a home. There are no fees to apply for a BMO Harris preapproval. A completed loan application, however, is necessary to receive a preapproval loan commitment.

How can I find out how much home I can afford?

It is best to schedule a mortgage consultation with one of our Mortgage Bankers. Find a Mortgage Banker near you or call us at 888-482-3781.

Which is better: fewer discount points or a lower interest rate?

It depends on how long you expect to own your home. The lower the interest rate, the lower your principal and interest payment. You must consider the monthly savings versus the extra point(s). Discount and interest points may or may not be tax deductible. Please consult your tax advisor to discuss your individual situation.

I locked my interest rate, but the Truth in Lending Statement says the annual percentage rate (APR) is higher. Am I getting a different rate?

No. The interest rate for your mortgage note will be the rate you selected when you signed your Price Protection Election Agreement. Unlike the interest rate, the APR includes certain charges and fees to reflect the total cost of the loan on an annual percentage basis. Please see the following question for information regarding the APR.

What is the annual percentage rate (APR)?

The Annual Percentage Rate (APR) is the total yearly cost of a mortgage stated as a percentage of the loan amount, which includes such items as the interest rate, private mortgage insurance and loan origination fees (points).

What is pre-paid interest?

Pre-paid interest is an amount you pay at closing which represents the interest that will accrue between the day your loan closes and the last day of that month. For example, if your loan closes on the 20th day of a 30-day month, at closing, you will pay interest owed for the remaining 10 days of that month.

Pre-paid interest covers the period between the day of your loan closing and your first mortgage payment. For each day between the closing date and the following 1st of the month, you'll pay daily (per diem) interest.

What is the benefit of an extended rate lock for new construction?

An extended rate lock option may be a good option when building a new home. Frequently, a new home will not be completed within the standard rate lock period. If this is the case, an extended rate lock may be a smart move for you. BMO Harris provides options offering up to fifteen months of interest rate protection, depending on your product choice.

What is the advantage to have BMO Harris hold my property tax escrow?

Convenience. By having a property tax escrow account with BMO Harris, you can budget by spreading the annual cost of property taxes throughout the year, and BMO Harris will make property tax payments on your behalf and you will not have to worry about missed or late payments.
