GET PRE-APPROVEDWhat Can Change Your Monthly Mortgage Payment?
Your monthly payment depends on more than the price of the home. Understanding these six factors can help you compare homes and make more informed decisions about your buying budget.
Home Price
The purchase price helps determine how much you need to finance. A higher home price generally means a larger loan and monthly payment unless the difference is offset by a larger down payment.
Down Payment
A larger down payment reduces the amount you need to borrow and can lower your monthly payment. Depending on the loan, putting less than 20% down may also result in mortgage insurance.
Interest Rate
Your mortgage rate has a significant impact on both your monthly payment and the total interest paid over the life of the loan. Even a relatively small rate change can affect buying power.
Loan Term
A longer loan term generally produces a lower monthly principal and interest payment, while a shorter term typically means a higher monthly payment but less interest paid over time.
Property Taxes & Insurance
Property taxes and homeowners insurance are often included in the monthly housing payment. These costs vary by property, location, assessed value, coverage and other factors.
HOA Dues
Some Whatcom County homes and condominiums have homeowners association dues. These fees vary by community and should be included when comparing the true monthly cost of different properties.

Frequently Asked Questions
A mortgage payment commonly includes principal and interest on the loan. Depending on your loan and escrow arrangement, your monthly housing payment may also include property taxes, homeowners insurance and mortgage insurance. If the property belongs to a homeowners association, HOA dues should also be considered when estimating the total monthly cost of owning the home.
This calculator is intended as a planning estimate rather than a loan quote. Your actual payment will depend on your loan amount, interest rate, loan program, property taxes, homeowners insurance, mortgage insurance if applicable, HOA dues and other costs. A lender can provide estimates based on your financial profile and the specific property you are considering.
There is not one property tax rate that applies to every home in Whatcom County. Property taxes are based on the property's assessed value and the levy rates of the taxing districts serving that property. Those districts can vary by location, so two similarly priced homes in different parts of Whatcom County may have different tax bills. Buyers should review the actual tax information for the specific property they are considering.
No. A 20% down payment is not required for every mortgage. Down-payment requirements depend on the loan program, lender and borrower qualifications. Conventional, FHA, VA and USDA financing can have different requirements. With many conventional mortgages, putting less than 20% down may require private mortgage insurance. A lender can help you compare the programs for which you may qualify.
Private mortgage insurance, or PMI, may be required on a conventional mortgage when the buyer makes a smaller down payment. PMI protects the lender rather than the borrower. Whether it is required and how much it costs depends on the loan. FHA, VA and USDA loans have their own mortgage insurance or program-fee rules, so they should be evaluated separately.
It depends on your financial goals. A 30-year mortgage generally spreads repayment over a longer period, which can reduce the required monthly principal and interest payment. A 15-year mortgage generally has a higher monthly payment but can substantially reduce the amount of interest paid over the life of the loan. Compare both options using your actual lender quotes rather than assuming one is always better.
The calculator on this page estimates a payment using the numbers you enter. A mortgage pre-approval is completed by a lender who reviews financial information such as income, assets, debts and credit to determine the loan amount and terms for which you may qualify. Getting pre-approved before seriously shopping for a Whatcom County home can give you a much clearer understanding of your buying budget.
Washington buyers may have access to state, federal or local homebuyer programs depending on income, property, loan type and other eligibility requirements. Programs and guidelines can change, so buyers should confirm current eligibility and terms with a participating lender or the appropriate housing agency before relying on assistance as part of a purchase.
