For the majority of us, purchasing a home is the largest purchase we will ever make, and it significantly affects daily living. For many people, their first house will be where they intend to raise a family or spend their first years of marriage. Not only that, but downsizing or moving into a larger home later in life also marks the beginning of a new chapter.


We want our home to be unique, but going over budget to realize that goal can be risky. This may ultimately result in a stressful new chapter instead of an exhilarating one.

The majority of people utilize mortgages to purchase homes, and even if they have limitations, you could still end up in a difficult situation. 80,490 homes have mortgage arrears of 2.5% or greater, according to UK Finance's February 2026 update. Before you buy the house at the top of your budget, there are a few things to think about.

Factors That Impact Affordability


Your income, debts, and down payment are the main determinants of affordability. The interest rate you receive also affects how much home you can buy because a lower interest rate could result in a considerably smaller monthly mortgage payment. Getting pre-qualified for a home loan can help you figure out a reasonable housing budget, even though your personal savings objectives or spending patterns may affect your affordability.

How Much House Can You Afford With Your Income?


Your income is a crucial consideration when determining your affordability. Your gross monthly income—that is, your salary before taxes and other deductions—will be used by mortgage lenders. Your income and the salaries of any co-borrowers should be combined when co-borrowing. Aim for the entire monthly housing costs (mortgage, property taxes, and insurance) to be no more than 30% of your gross monthly income when figuring out how much house you can afford with your income.


Based on these principles, the maximum property price you might be able to pay is roughly estimated in the following table. Remember that the pay should be the total of your income plus the salaries of any other borrowers. Estimates for taxes, insurance, and private mortgage insurance (PMI) are included in these computations, while these figures might differ greatly depending on your particular metro region, loan terms, and down payment. The Affordability Calculator's "advanced" dropdown menu allows you to change these figures.

How To Determine Affordability

You may personalize your payment information with Zillow's affordability calculator, which also offers helpful ideas in each field to help you get started. You can determine affordability using your projected monthly payments and down payment amount, or using your annual income, monthly bills, and down payment.

In order to provide you with a more precise assessment of the affordability of your home, our calculator also incorporates sophisticated filters, such as precise amounts of property taxes, homeowner's insurance, and (if required) HOA dues. To get your optimal home budget, find out more about the line items in our calculator.

Home Loan

Before taxes and other deductions, this is the whole amount of money earned for the year. The amount is typically listed on your W2 form. To determine your annual income if you have a co-borrower who will make mortgage contributions, add together both of their incomes.

Total amount owed each month

These are regular monthly costs like school loans, minimum credit card payments, or auto payments. If necessary, you can modify this sum using our affordability calculator. For instance, your monthly debt would be $300 if you had a $250 auto payment and a $50 minimum credit card payment.

Annual Earnings


Before taxes and other deductions, this represents the entire amount of money generated for the year. The amount is often seen on your W2 form. To determine your annual income if you have a co-borrower who will contribute to the mortgage, add up both of their incomes.

Total Monthly Debts


These are regular monthly costs such as student loans, minimum credit card payments, or auto payments. This figure can be changed as necessary using our affordability calculator. For instance, your monthly debt would be $300 if you had a $250 monthly auto payment plus a $50 minimum credit card payment.

A down payment


The sum of money you have to pay for a house up front. A minimum 3% down payment is required for the majority of house loans. To reduce your monthly payment, avoid private mortgage insurance, and improve your affordability, a 20% down payment is the best option. A 3% down payment on a $250,000 house is $7,500, while a 20% down payment is $50,000.

Ratio of debt to income (DTI)

The percentage is calculated by dividing the total amount of your monthly debt payments by your gross monthly income. Lenders can assess your ability to make monthly payments and return the money you intend to borrow by looking at your DTI.


By default, our affordability calculator will recommend a DTI of 36%. With our DTI Calculator, you may assess your debt-to-income ratio.

Interest Rate 


The sum that a borrower must pay a lender to obtain a loan. A yearly percentage of the loan total is typically used to express the interest rate. Until the loan is fully repaid, the borrower pays payments to the lender over a certain period of time, including interest. The current national average mortgage rate is used in our affordability calculator. Your credit score and down payment are two examples of the variables that will affect your interest rate. Determine the interest rate on your mortgage.

Term Of Loan


The amount of time you commit to repaying the house loan. Although 30 years, or 360 months, is the most typical mortgage length, there are other durations available based on the kind of house loan that best suits your needs. The advanced options in the affordability calculator allow you to change your loan duration (in months).

Tax On Real Estate


Your affordability may be impacted by the annual property taxes you pay when you own a home, which are determined by the property's assessed value or purchase price. Each state, county, and municipality may have a different tax rate.


By default, our calculator uses a property tax rate; however, you can change this amount using the advanced settings. Get pre-qualified at Zillow Home Loans to receive a more precise total payment amount.

HOI Or Homeowner's Insurance


One kind of property insurance that protects a residential residence is called homeowner's insurance. Typically, obtaining a home loan requires HOI. The price may change based on your insurance carrier, region, kind of coverage, and any applicable discounts. For every $100,000 of the home's value, homeowner's insurance typically costs about $35 per month. To find out the precise amount, speak with your insurance provider. The advanced options allow you to change the calculator's default value.

Insurance For Private Mortgages (PMI)


If a borrower makes a down payment of less than 20% on a house purchase, many lenders frequently demand private mortgage insurance. When a borrower defaults on a home loan, PMI shields the lender from potential damages. The PMI is determined using our calculator based on the down payment and house price. The affordability calculator's advanced options allow you to select whether or not to incorporate PMI.

Dues For The Homeowner's Association (HOA)


A homeowner's association (HOA) oversees certain communities, like townhomes and condos, and charges a monthly fee to maintain common spaces and enforce rules and regulations. Your affordability may be impacted by any monthly HOA dues you pay. This figure can be changed using the advanced options of the affordability calculator.

How Much Of A Mortgage Am I Eligible For?


In order to assess how much they are willing to lend you, lenders use a pre-qualification process that considers your financial situation, including debt and income. A pre-qualification letter outlining your eligibility for a mortgage is often provided by the lender after a preliminary evaluation. To verify your affordability, get pre-qualified by a lender.

Most Affordable Markets For Homebuyers


According to a Zillow research, 27% of active listings were within the reach of the average household, a decrease of 12 percentage points from pre-pandemic levels and an improvement over the previous year.


Due to lower mortgage rates, a slower fall selling season, and increased seller competition, nearly every market examined in September 2024 had higher affordability.

The top ten most reasonably priced marketplaces (out of the 50 biggest in the country) are included in the table below. Depending on the current mortgage rate, the average local homeowner's salary, and the average local home value, the percentage of income allocated to a mortgage may change.
