In Idaho how do banks and lenders calculate what mortgage payment I can afford?
In Idaho the general rule of thumb for determining the mortgage amount a borrower can manage is 2 – 2.5 times your monthly GROSS income. For example, someone earning $100k annual can afford a $200k – $250k mortgage. However, this is only a general guideline and there is more to the process. In addition to your gross income, lenders take into consideration two ratios: the “front-end ratio” and the “back-end ratio.” The front-end ratio is your mortgage-to-income ratio, representing the (monthly) amount of your income which you can dedicate to paying your mortgage. The ideal ratio is under 30%–although some lenders will allow you to exceed 40%. The back-end ratio is your debt-to-income (DTI) ratio, or the amount of gross income you must cover your debts (loans for cars, education, and credit cards, for example). Most lenders want to see that number no more than 36% (36% of your income goes to paying debts). Although there are other factors in determining your overall financial “health,” these best represent your ability to pay the mortgage.
In Idaho what are other costs that can increase my mortgage payment?
In Idaho the mortgage payment includes multiple factors, each which can increase (or decrease) the actual mortgage payment. Other than then actual cost of the home, you need to include the following variables:
- Down Payment (the amount of money you pay up front, not borrowed from the lender)
- Interest Expenses (the interest rate, the length of the loan and type—whether a fixed or adjustable interest rate)
- Property Taxes (these vary with the community you are moving into)
- Insurance (homeowner’s insurance rates will depend on your coverage and can fluctuate)
- PMI (some lenders require insurance to protect them should you default on the loan)
- HOA Fees (Some residential communities (especially condominiums and other PUDs) have maintenance fees for shared facilities and amenities offered in the development
In Idaho how do I calculate my mortgage payment?
When considering a new home purchase or whether to refinance your current mortgage, the best place to start is by estimating your monthly payment. You can utilize our free Idaho calculator to get a quick estimate. However, you will need a few numbers available:
Mortgage principal (how much you want to borrow—not necessarily the cost of the property).
Monthly interest rate (the fee you pay the bank to borrow money: check out current mortgage rates). This is usually reflected as an APR (annual percentage rate) and is translated to a monthly rate by dividing the rate by 12 (months).
Number of payments (how long do you want to pay on the mortgage). This is easy with a fixed mortgage, but not with an ARM, where the rate will change on a regular basis.
Property taxes (usually the cost of taxes is added to the mortgage payment & added to an escrow account, where the taxes are paid on your behalf at the end of the year).
Homeowner’s Insurance (since type and coverage vary widely, it is best to contact an agent to get some estimates).
PMI, if required (most lenders require this additional insurance when you put down less than 20% of the purchase price of the property).

Calculator questions?
In Idaho what is the formula for calculating mortgage payments?
Whether you are a math nerd who aspires to do the math by hand or simply want to understand how Idaho mortgage payments are calculated, the formula looks like this:
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]
Key:
- M = monthly mortgage payment
- P = principal amount
- I = monthly interest rate (usually listed as an annual percentage rate)
- N = number of payments over the life of the loan (360 payments for 30 years, etc)
In Idaho how do I calculate interest with my mortgage payment?
In Idaho if you are obtaining a fixed mortgage, whether it be 30, 15, or even 5 years, you are probably curious to see how much you are paying in interest. One thing to remember is that in the U.S., interest is paid in arrears. So, your monthly payment includes interest for the 30 days BEFORE your due date. Since fixed mortgages are fully amortized installment loans, the amortization schedule shows how the split between principal and interest changes over time. In the early years of the mortgage term, most of your payment will go towards interest. However, as you pay down the principal, less interest will accrue and more of your payment is applied to the principal.
In Idaho what mortgage products will help keep my mortgage payments down?
In Idaho the longer you finance your home for, the lower your monthly payments will be. Conversely, a shorter (or adjustable rate) term usually equates to a lower interest rate. Its important to run the numbers on multiple scenarios to find out what works best for you.
If you already have a mortgage and are looking for an opportunity to lower your current monthly payments, consider the following:
- Refinance at a lower rate
- Refinance to a longer term
- Eliminate mortgage insurance
- Apply for mortgage forbearance or loan modification (in case of financial hardship)
In Idaho what is an amortization schedule calculator?
In Idaho an Amortization Schedule calculator provides a schedule of how much is paid for each portion of the mortgage payment over time. A mortgage calculator allows you to plug in the mortgage amount, term (number of payments) and the APR (interest rate per year) and determine the total you will pay in principal and interest over the life of the loan.
