How much house can you actually afford in Utah?

Every week someone sits down with us holding a pre-approval letter from another lender for a number that makes them nervous. They are right to be nervous. A pre-approval tells you the most a lender is willing to lend. It does not tell you what you can comfortably pay while still saving for retirement, taking a trip to Moab and replacing a water heater when it fails in February.

This guide walks through how lenders calculate affordability, where the Utah market adds wrinkles, and the simple method our loan officers use to set a budget that holds up.

How lenders calculate the maximum

Mortgage underwriting is built around the debt-to-income ratio, or DTI. It compares your total monthly debt payments with your gross monthly income, before taxes.

Front-end ratio: your full housing payment (principal, interest, property tax, homeowners insurance, mortgage insurance and HOA dues) divided by gross income.
Back-end ratio: the housing payment plus car loans, student loans, credit card minimums and other debts, divided by gross income.

Conventional loans often allow a back-end ratio up to 45% to 50% with automated approval. FHA can stretch past 55% in some cases. Those limits exist so that more people can qualify, not because a 50% DTI is a comfortable way to live.

We start with the payment, not the price. Here is the three-step approach.

1. Anchor your housing payment near 28% to 31% of gross income

For a household earning $110,000 a year, that is roughly $2,570 to $2,840 per month for the full payment. It leaves room for the costs lenders never see: childcare, retirement contributions, groceries and the occasional ski pass.

2. Subtract the costs that are not principal and interest

In Salt Lake County, property taxes run about 0.55% of value per year on a primary residence, which is low nationally. Insurance on a typical single-family home is about $90 to $140 per month. Add HOA dues if you are looking at townhomes in Daybreak or Lehi, which often run $90 to $250.

3. Convert the remaining principal and interest into a price

At a sample rate of 6.125% on a 30 year fixed loan, every $1,000 of monthly principal and interest supports about $164,000 of loan. If $2,200 of your budget is left for principal and interest, that supports roughly a $361,000 loan. Add your down payment to get your price range.

A comfortable budget is the payment you would still choose if your income stayed flat for three years.

Utah-specific things to factor in

Growing families. Utah has the youngest median age in the country. If a new baby or daycare costs are likely in the next few years, build that into your budget now.

Basements and utilities. Many Wasatch Front homes have large basements, which is great for space but adds to heating costs in January. Ask the seller for 12 months of utility bills.

New construction timelines. Buying a build in Eagle Mountain or Saratoga Springs can mean 6 to 9 months before closing. Extended rate locks cost a little more but protect your budget if rates move.

Second income from basement apartments. Some programs allow you to count part of expected rent from an accessory unit. It can help you qualify, but budget as if the unit sits empty for a few months.

What about the down payment?

A bigger down payment lowers your loan amount and can remove mortgage insurance, but emptying your savings is risky. We suggest keeping at least three months of expenses in reserve after closing. For many first-time buyers, 3% to 5% down with a healthy emergency fund is a better plan than 20% down with nothing left.

A quick example

Consider a couple in Herriman earning $118,000 combined with a $420 car payment and $180 in student loans.

Target housing payment at 29%: about $2,850 per month
Taxes, insurance and HOA: about $560 per month
Principal and interest budget: about $2,290 per month
Supported loan at 6.125%: about $376,000
With 5% down, a comfortable price: about $395,000

The lender maximum for the same couple might be closer to $520,000. That $125,000 gap is the difference between a house that fits and a house that runs your life.

Your next step

Run your own numbers with our affordability calculator, then talk to a loan officer about programs that lower your cash to close. A pre-qualification takes about six minutes and uses a soft credit check that does not affect your score.
