The affordability calculator is calculated based on the percentage of your income spent on monthly debt. Most lenders limit how much of your monthly income can pay debt such as mortgage payments, car loans, and student debt (this is called Debt to Income ratio). The conventional limit is 36% of your monthly income, but this could be higher for FHA loans. Your remaining income after debt and taxes should be enough to cover living expenses and savings goals. It is also wise to have cash set aside to pay for any large unexpected repairs or financial emergencies.

Terms/Definitions

Annual income

This is the combined annual income for you and your co-borrower. Include all income before taxes, including base salary, commissions, bonuses, overtime, tips, rental income, investment income, alimony, child support, etc.

Down payment

This is the amount of money you will put towards a down payment on the house. Make sure you still have cash left over after the down payment to cover unexpected repairs or financial emergencies.

Monthly debt

Include all of you and your co-borrower's monthly debts, including: minimum monthly required credit card payments, car payments, student loans, alimony/child support payments, any house payments (rent or mortgage) other than the new mortgage you are seeking, rental property maintenance, and other personal loans with periodic payments.
Do NOT include: credit card balances you pay off in full each month, existing house payments (rent or mortgage) that will become obsolete as a result of the new mortgage you are seeking, or the new mortgage you are seeking.

Interest rate

This is the interest rate for the loan you will receive. By default, the current 30-yr fixed average rate on Zillow Mortgage Marketplace will be used.

Debt to income (DTI)

Your DTI is expressed as a percentage and is your total "minimum" monthly debt divided by your gross monthly income. The conventional limit for DTI is 36% of your monthly income, but this could be as high as 41% for FHA loans. A DTI of 20% or below is considered excellent.

Income taxes

This is an annual tax that governments place on individuals' income. It includes federal tax, most states and some local entities. The national average is around 30% but can vary based on income, location, etc.

Property taxes

The mortgage payment calculator includes estimated property taxes. The value represents an annual tax on homeowners' property and the tax amount is based on the home's value.

Homeowners insurance

Commonly known as hazard insurance, most lenders require insurance to provide damage protection for your home and personal property from a variety of events, including fire, lightning, burglary, vandalism, storms, explosions, and more. All homeowner's insurance policies contain personal liability coverage, which protects against lawsuits involving injuries that occur on and off your property.

Mortgage insurance (PMI)

Mortgage insurance is required primarily for borrowers with a down payment of less than 20% of the home's purchase price. It protects lenders against some or most of the losses that can occur when a borrower defaults on a mortgage loan. Also known as PMI (Private Mortgage Insurance).

HOA dues

Typically, owners of condos or townhomes are required to pay homeowners association dues (known as HOA fees), to cover common amenities or services within the property such as garbage collection, landscaping, snow removal, pool maintenance, and hazard insurance.

Loan term

This is the length of time you choose to pay off your loan (e.g., 30 years, 20 years, 15 years, etc.)
