When you’re ready to take the plunge into homeownership, you must ask yourself one important question: How much house can I afford? The true cost of homeownership is more than just the down payment and monthly mortgage payments, so be sure to consider all these factors.
How to calculate home affordability
Your monthly expenses compared to your monthly income, your credit score and home location will all factor into the equation. To get an accurate estimate, crunch the numbers with our home affordability calculator.
How to calculate annual income
To find your total income, add up all the money you have coming in throughout the year, including:
Income from employment (wages, salaries and tips)
Trust income
Interest from CDs and savings accounts
Investment dividends
Social Security and other benefits
Any funds taken from a retirement fund or pension

What is the 28/36 rule and how does it work?
The 28/36 rule stipulates you should spend no more than 28% of your gross monthly income on your monthly home-related costs. The rule also suggests spending no more than 36% on your monthly total debt payments, including your mortgage, credit cards and other loans, like auto and student loans.
How does my debt-to-income ratio affect affordability?
In general, a lower debt-to-income ratio (DTI) is better for securing a home loan at a good rate. To find your DTI, take the total amount of your monthly mortgage plus any other monthly debt payments (credit cards, student loans, medical debt), and divide by your monthly gross income. The resulting percentage represents your monthly income that goes toward debt.
Most lenders prefer a DTI of 36% or below, though some will accept a DTI under 50%. You can use the calculator below to get an idea of your DTI.
How much down payment do I need for a house?
The amount you need to put down depends on your home’s purchase price and your loan type. Down payments typically range from as little as 3% up to 20%. If you can afford it, a larger down payment can reduce the amount you spend in the long run by lowering the amount you pay in interest over the life of the loan.

How does credit score affect availability?
Lenders will heavily consider your credit score when determining your mortgage rate. For example, a credit score of 750 is considered by FICO in the “very good” range and could put you in the running for a better interest rate than a comparatively lower score. You can take steps to improve your score if it could use a boost.
Types of home loans
With Ally Home, a home loan expert can help you understand which loan type is right for you.
Fixed-rate loan
With this loan type, the interest rate is locked in for the life of the loan, which means your monthly payment will not change. This stability makes a fixed-rate loan a good choice if you prefer predictable payments.
Adjustable-rate loan
With an adjustable-rate loan, your interest rate can change throughout the duration of your loan. An adjustable-rate mortgage may make more sense when you don’t plan to live in your home for many years.
Jumbo loan
Jumbo loans are used for borrowing more than the limits set by Fannie Mae and Freddie Mac. To qualify for an Ally Home jumbo loan, you usually need a credit score of at least 680-700, a DTI of 49.99% and a higher down payment.
First-time homebuyer programs
If you’re a first-time homebuyer, you may be able to qualify for a loan through the Fannie Mae HomeReady® or Freddie Mac HomeOne® programs. Those offer 3% down payment options for eligible borrowers and are both available through Ally Home.
