If you want to buy a $300,000 house in Michigan, most buyers need roughly $70,000 to $100,000 in household income to qualify, depending on your debt and your down payment. As of June 2026, property taxes in a lot of Oakland and Macomb County suburbs run about 1.4% to 2.0% of value per year, and that tax bill is a big reason the income number swings so much from one city to the next.
That is the short answer. The real answer depends on your numbers. Here is exactly how I walk a Michigan buyer through it.
The one ratio that decides everything
Lenders do not approve you on income alone. They approve you on debt-to-income ratio (DTI). That is your total monthly obligations, including the new house payment, divided by your gross monthly income.
For most loans, the target is a total DTI at or below about 45% (sometimes higher with a strong file). Flip that around and it becomes a simple rule: your house payment plus all your other monthly debt should stay under 45% of what you earn before taxes.
So the income question is really three questions. What does the house cost per month? What other debt do you carry? And what income makes those two numbers fit under 45%?
What a $300,000 house costs per month in Michigan
Let me build a realistic local scenario. Assume 5% down ($15,000), a conventional 30-year loan, taxes near the Michigan suburban average, homeowners insurance, and private mortgage insurance because we are under 20% down.
All in, a $300,000 purchase with 5% down lands many Michigan buyers in the range of roughly $2,400 to $2,600 a month for principal, interest, taxes, insurance, and PMI combined, based on today's market. Taxes are the wild card. A home in a higher-millage city can push that payment up by a couple hundred dollars a month versus a lower-tax suburb at the same price. (Payments and market conditions change, so treat this as a framework, not a quote.)
For the math below I will use $2,500 a month as the all-in housing payment.
How much income, in three real scenarios
Now layer in your other monthly debts and solve for the income that keeps you under 45% DTI.
Scenario 1: low debt (around $200 a month). Total obligations are about $2,700. Divide by 0.45 and you need roughly $6,000 a month, or about $72,000 a year. I see plenty of Michigan buyers here, especially first-timers who kept their cars paid off. If that is you, my Michigan first-time buyer guide walks through the down payment side in detail.
Scenario 2: typical debt (around $700 a month). Think one car payment, a small student loan, a credit card minimum. Total obligations are about $3,200. Divide by 0.45 and you need roughly $7,100 a month, or about $85,000 a year. This is the most common profile I see for a $300,000 purchase.
Scenario 3: heavy debt (around $1,250 a month). Two car payments, a student loan, and a card. Total obligations are about $3,750. Divide by 0.45 and you need roughly $8,300 a month, or about $100,000 a year for the same house.
Look at what just happened. Same price, same payment, but the income needed jumped almost $30,000 a year purely because of debt. That is the part most buyers miss. Paying down a car loan can do more for your approval than a raise.
Your down payment moves the number too
Everything above assumed 5% down. Change the down payment and three things move: your loan amount, your PMI, and sometimes your costs. More down means a lower payment, which means less income required. Cross 20% down and PMI falls off entirely, which can drop the payment and the income bar at the same time. Less down (3% conventional or a low-down option) raises the payment, so it raises the income you need.
Michigan buyers also have help most people never ask about. MSHDA, the state housing authority, offers down payment assistance that can change which of these scenarios you land in. It is worth checking before you assume you are priced out.
Why this matters
If you own a home: the same DTI math decides whether you can buy the next one before selling, or tap equity without wrecking your ratios. Know your number before you shop.
If you are a home buyer: do not guess at affordability from the price tag. The income you need is driven by your debt and your down payment as much as the price. Run your real numbers first so you shop with a payment you actually want.
If you are a home seller: your buyer pool for a $300,000 listing is mostly households in that $72,000 to $100,000 income band. Pricing and concessions that help a buyer's payment widen that pool. If deals keep stalling, my notes on why deals fall apart may help.
If you are a real estate agent: when a client says "the payment is too high," that is usually a financing problem, not a dead deal. Debt paydown, a different down payment, or assistance programs can move a buyer from "no" to "approved." Loop in a lender early instead of losing the deal.

Frequently asked questions
What credit score do I need to buy a $300,000 house in Michigan?
Most conventional loans want a score in the mid-600s or higher, and FHA can go lower. A stronger score helps your PMI and your monthly payment, which lowers the income you need to qualify. Talk through your file before assuming a score rules you out.
How much should I put down on a $300,000 home?
You can buy with as little as 3% to 5% down on many programs. More down lowers your payment and your PMI, and crossing 20% removes PMI entirely. The right number depends on your savings and how much monthly payment you want to carry.
Do Michigan property taxes really change how much income I need?
Yes, a lot. Taxes in many Oakland and Macomb County suburbs run about 1.4% to 2.0% of value per year. A higher-tax city can add a couple hundred dollars to the monthly payment on the same price, which raises the income you need to stay under a healthy DTI.
What is the income limit if I have car loans and student loans?
There is no fixed limit, but your other debt directly raises the income required. On a $300,000 home, heavy monthly debt can push the income needed from around $72,000 toward $100,000 a year. Paying down a loan before you apply can have a bigger effect than a raise.
