How Much House Can You Afford in North Phoenix on a $100K Income?
The short answer
On a $100K household income, how much house you can afford in North Phoenix depends less on the income itself and more on your monthly debts, your savings, your credit, and the property taxes, HOA dues, and insurance on the specific home. Lenders look at your debt-to-income ratio, not just your salary. Two buyers earning the same $100K can end up with very different price ranges, so the honest answer is: let's run your real numbers before you fall in love with a listing.
I've been doing mortgages for 25 years, and "how much house can I afford?" is still the first question almost everyone asks me. It's a great question. It's also the one that the online calculators get wrong most often, because they plug in a generic income and a generic everything-else and spit out a single number that may have nothing to do with your actual life.
I live in North Phoenix, in 85028, just north of Piestewa Peak. When I say North Phoenix, I mean anywhere north of the Peak, up toward Anthem, roughly from I-17 over to the Scottsdale border. That's a big area with a big spread of home prices, and that spread is exactly why a $100K income can feel like plenty in one zip code and tight in the next.
So let's walk through how I actually think about affordability, without the guesswork.
Where North Phoenix Prices Sit Right Now
Before you can answer "how much can I afford," you need to know what homes actually cost where you want to live. Here's a snapshot from recent data:
City of Phoenix overall: Redfin data reported by the Copper Courier put the Phoenix median sale price at roughly $459K as of spring 2026, essentially flat year over year.
85022: Redfin showed a median sale price around $449K over the three months ending August 2026.
85024: Redfin showed a median closer to $618K over the same period.
Same city, a few miles apart, and the medians differ by well over $150K. That's North Phoenix in a nutshell. Medians also move month to month and vary by source, so treat these as a starting point, not a quote. The good news: North Phoenix has homes across a wide range of price points, from condos and townhomes to larger single-family homes with RV gates and pools.
How Lenders Actually Decide What You Can Afford
Your income is only one piece. The number that drives most approvals is your debt-to-income ratio (DTI): your total monthly debt obligations, including the new housing payment, divided by your gross monthly income.
What counts as "debt"
Car loans, student loans, minimum credit card payments, personal loans, child support or alimony, and the new housing expense (principal, interest, property taxes, homeowners insurance, mortgage insurance if any, and HOA dues). Things like groceries, utilities, and your streaming subscriptions don't count toward DTI, but they absolutely count toward whether you'll be comfortable.
Typical DTI guidelines
Guidelines vary by loan program and by the strength of the whole file. As a general reference from industry sources, conventional loans can allow DTI up to around 50% with automated approval, though many approvals land in the low-to-mid 40s. FHA can stretch higher with strong compensating factors like reserves or a solid credit history. Those are ceilings, not targets. Just because a lender will approve a number doesn't mean you should spend it.
Why two $100K earners get different answers
Picture two buyers, both at $100K. Buyer A has no car loan and no student debt. Buyer B has a truck loan and student loans. Same income, but Buyer B has a big chunk of their DTI already spoken for before we even talk about a house. Add in differences in credit score, savings, and which home they choose (a home with a hefty HOA versus one with none), and their realistic price ranges can be far apart.
Budget Like You're Drafting a Fantasy Football Team
I play fantasy football every year, and I've noticed that the best drafters and the best homebuyers think the same way. Nobody wins a league by spending their whole auction budget on one superstar and then filling the rest of the roster with whoever's left. You plan the whole roster.
Your home budget works the same way. Before you pick the "first-round" item, the house price, you need to know what the rest of your roster costs:
Property taxes: Vary by parcel and by city. Look up the actual tax bill on any home you're serious about.
HOA dues: In North Phoenix these range from nothing at all in some older neighborhoods to meaningful monthly amounts in master-planned communities. Ask for the dues and any special assessments up front.
Homeowners insurance: Quotes vary by the home's age, roof, and features like a pool.
Summer power bills: This is the Phoenix-specific one people forget. A bigger, older home with an aging AC unit can make July and August expensive. Ask the seller for utility history if you can.
Pool and yard care: If the home has a pool, budget for chemicals, equipment, and possibly service.
Reserves: Savings left over after closing. Lenders like to see them, and so will you the first time the water heater gives out.
In fantasy football you keep a little budget left over for the waiver wire, because injuries happen. In homeownership, that's your emergency fund. Don't draft it away.
What About the Down Payment?
This is where a lot of buyers on a $100K income sell themselves short. Many people assume they need a huge pile of cash before they can buy. In reality, there are low down payment options for qualified buyers, including certain conventional and FHA programs, and VA loans for eligible veterans. There are also down payment assistance programs in Arizona that some buyers qualify for, depending on income limits and other rules.
The right choice depends on your savings, your credit, and how you want your monthly budget to look. A smaller down payment may get you into a home sooner. A larger one can reduce your loan amount and, in some cases, mortgage insurance. There's no one-size-fits-all answer, which is why I like to show buyers side-by-side scenarios with their real numbers.
Don't forget closing costs, either. In some cases, sellers can contribute toward those costs, within program limits. That's a negotiation tool worth discussing before you write an offer.
Why a Broker Can Change the Answer
I'm an independent mortgage broker with access to 180+ wholesale lenders, and I personally handle every file from start to finish. That matters for affordability because different lenders have different overlays, which are extra rules on top of the baseline program guidelines. One lender may be stricter on DTI or credit than another for the same loan type.
When you work with a single bank, you get that one bank's box. When I shop your file, I'm looking for the lender whose guidelines fit your situation. That can be the difference between the price range you were told and the price range you actually qualify for. It also means I can compare programs and pricing across lenders so you see your real options, not just one.
And to be clear, I'm not the underwriter. The lender's underwriter makes the final credit decision. My job is to package your file correctly, match it to the right lender, and keep things moving so there are no surprises late in the game.
Where a $100K Income Can Go in North Phoenix
Without quoting any payments (those depend on your rate, loan program, taxes, and insurance on the specific home), here's how I'd frame the search:
Condos and townhomes across North Phoenix often sit at lower price points, but check the HOA dues carefully, since they count in your DTI.
Older single-family neighborhoods south of the 101 and around the Paradise Valley Village area can offer larger lots and no HOA, though you may want to budget for updates.
Master-planned areas farther north tend to run higher and usually come with HOA dues, along with amenities like parks, pools, and trails.
One thing I love about North Phoenix, and a big reason I live here, is that it's convenient to all the good spots in the Valley and has strong employment options nearby. That makes it easier to find a home that fits both your budget and your commute.

FAQ: Affording a Home in Phoenix
How much house can I afford in Phoenix making $100K a year?
It depends on your existing monthly debts, credit, savings, and the taxes, insurance, and HOA dues on the home you choose. Lenders focus on your debt-to-income ratio. The fastest way to get a real answer is a pre-approval with your actual numbers.
What debt-to-income ratio do I need to buy a house?
It varies by program and the strength of your file. Conventional loans can go up to around 50% DTI in some cases, and FHA can allow higher with compensating factors. Many buyers feel more (and smartly so) comfortable well below the maximum.
Is the 28/36 rule still how lenders decide?
It's a useful personal budgeting guideline, but lenders often approve ratios above it depending on the loan program, credit, and reserves. Use it as a comfort check, not a hard limit.
Do HOA fees affect how much house I can afford?
Yes. HOA dues are included in your housing expense when lenders calculate DTI, so a home with higher dues can lower the price range you qualify for.
Can I buy a home in North Phoenix without a large down payment?
There are low down payment options for qualified buyers, plus Arizona down payment assistance programs with their own eligibility rules. I'll walk you through which ones fit your situation.
