Pairs with the Affordability calculator

You don't have to have perfect credit to be able to purchase a home.

Brycen Brown & Alex Lopez · Brown mortgage advisors

Most buyers who think they're not ready are closer than they think. Steady income counts for more than a big one, and down payment assistance can lower the cash you need to bring. Watch first, then plug your own numbers into the calculator below.

  1. The most important number is: can you afford the payment?
  2. I think they think that they need a boatload of cash. You don't, really. There's a lot of products out there to help, down payment assistance products, whatever it may be. So you really don't have to have that much cash.
  3. Same with the credit. You don't have to have perfect credit to be able to purchase a home. Of course, the better it is, the better pricing and the better products available to you, but it doesn't have to be perfect.
  4. Yeah, I'd say it's not any one thing. You have to have the whole picture.
  5. A lot of folks that are in a good spot to buy, they have good jobs. Good jobs doesn't necessarily mean high-paying jobs. That means they've been there for a while. They have stable income.
  6. You have people who are real nervous. You answer all the questions, you make them feel good, they fill out the application. And then it turns out, you know, this is fine. You didn't have anything to worry about.
  7. Are there times where that's obvious? Yeah, of course. But I think a surprising amount of the time, when people think "I don't know if I can do this," they're actually able to, or they're not that far off.

Advisor's Take

Thinking about waiting for rates to drop?

In any market, you can find the opportunity. You just have to be educated.

Blake Brown · VP | Senior Mortgage Advisor

Waiting for rates to drop has a cost too. With less competition, a seller may be more willing to help with your closing costs or a rate buydown. Watch Blake's story, then compare renting and buying in the calculator above.

Read along: full transcript
  1. This client called me and said, "Hey, I'm probably about a year or two out from buying a house." I was asking, why specifically one to two years? And they said it's just because of where interest rates are right now.
  2. Let's reframe the mindset here. There's not as much demand right now in the market because interest rates are, quote unquote, higher. Now you're not facing as much competition.
  3. The seller could be a lot more willing to give you concessions toward paying for your closing costs, or buying down your interest rate permanently or temporarily.
  4. And after that discussion and reframing his mindset, it went from maybe one or two years from now to, "Hey, we got pre-approved that day," and now he's out shopping.
  5. It's not selling at all. Again, a real honest discussion with them, and I'm just laying out the truth.
  6. In any market, you can find the opportunity. You just have to be educated.

Seller concessions and rate buydowns depend on the purchase contract, the loan program and lender guidelines. Rates and market conditions change.

What a calculator can't tell you

A calculator is only as good as its assumptions. Three things change your real number more than any slider, and a pre-approval is where they get verified.

  • How your income documentsSelf-employment, commission, bonuses, and seasonal pay are averaged and adjusted by lenders, and tax write-offs can lower your qualifying income.
  • Where your down payment comes fromGift funds, the sale of a current home, and retirement or investment assets each have their own documentation rules.
  • Your local costsIllinois has some of the highest property taxes in the country, and insurance and HOA dues vary by county and building. They can move your payment by hundreds a month.

Mortgage calculator questions, answered

Using the calculators

Will using these mortgage calculators affect my credit score?

No. Our calculators never check your credit. They only use the numbers you type in, and nothing is stored or reported. Your credit is reviewed only when you apply for a pre-approval, and mortgage credit checks made within a short shopping window (14 to 45 days, depending on the scoring model) are typically counted as a single inquiry.

How accurate are the calculator results?

They're as accurate as the numbers you enter. The math follows the same formulas lenders use for principal, interest, taxes, insurance, mortgage insurance, and debt-to-income. What a calculator can't know is your actual credit score, the property's exact tax bill, your insurance quote, or how your income documents. A Brown loan advisor replaces those assumptions with verified figures during pre-approval.

What's included in the estimated monthly payment?

Principal, interest, property tax, homeowners insurance, mortgage insurance, and HOA dues. Lenders call the first four PITI. Property taxes matter more here than most places: Illinois has some of the highest property tax rates in the country, so a home in Madison County or DuPage County can carry a much higher monthly payment than the same price in another state. Set the property tax field to match the area you're shopping.

Affordability

How much house can I afford?

Your price limit is set by whichever runs out first: your income, your existing debts, or your cash to close. Lenders compare your total monthly debts, including the new house payment, to your gross monthly income. That ratio is your debt-to-income, or DTI.

Example: with $8,000 a month in gross income and a 45% DTI ceiling, your total debts can reach $3,600. If you already pay $600 a month on a car and student loans, about $3,000 is left for the full house payment. The affordability calculator works backward from that number to a home price.

What debt-to-income ratio do mortgage lenders allow?

Most conventional loans approve up to about 45% DTI, and some go to 50% with strong credit and savings. FHA loans can allow higher ratios when the file has compensating factors. VA loans look at DTI alongside a separate residual income test. The often-quoted 28/36 rule is a comfort guideline, not a lending limit. Many buyers choose a payment below their maximum approval, and that's a smart call.

Do I need 20% down, and what happens if I put down less?

No. Conventional loans can start at 3% down for qualified first-time buyers, FHA at 3.5%, and VA and USDA loans can require nothing down. Putting down less than 20% on a conventional loan adds private mortgage insurance (PMI), commonly around 0.3% to 1.5% of the loan amount per year depending on credit and down payment. You can request PMI removal at 20% equity, and it ends automatically at 22% based on the original value. FHA mortgage insurance follows different rules, so ask us how it applies to your loan.

Rent vs. buy

Is it better to rent or buy a home right now?

It depends mostly on how long you'll stay. Buying has upfront costs (down payment, closing costs) and selling costs later, so owning usually pulls ahead only after several years of building equity and paying down principal. Renting keeps your cash flexible. The rent vs. buy calculator compares both paths side by side over the same time period using your rent, the home price, and your expected time in the home.

How long do I need to stay in a home for buying to make sense?

A common rule of thumb is five years, but your break-even year can be shorter or longer. It moves with the price-to-rent ratio in your area, your interest rate, how fast home values and rents rise, and how much you put down. Run the calculator with the years you realistically expect to stay, then try a shorter stay to see how much risk you're taking on.

Refinance

When does refinancing my mortgage make sense?

Refinancing makes sense when you'll keep the loan longer than it takes your savings to cover the closing costs. That point is called break-even. To find it, divide your total refinance closing costs by your monthly savings. Example: $5,000 in costs divided by $200 a month in savings equals 25 months. If you plan to stay well past that, the refinance pays off. Refinance closing costs typically run about 2% to 5% of the loan amount.

Keep in mind that restarting a 30-year term can lower your payment but raise the total interest you pay over the life of the loan. The refinance calculator shows both numbers.

How much does my rate need to drop to refinance?

There's no magic number. The old "one percent rule" is a starting point, not a requirement. On a large balance, a smaller drop can still produce meaningful monthly savings and a short break-even. On a small balance, even a full point may not cover the costs. Other reasons to refinance include removing mortgage insurance, switching from an adjustable to a fixed rate, shortening your term, or taking cash out.

From estimate to approval

Are closing costs included in the calculator results?

Closing costs are separate from your monthly payment estimate. For a purchase, plan on closing costs of roughly 2% to 5% of the price, on top of your down payment. Within three business days of your application, you'll receive a Loan Estimate that itemizes every fee. Sellers can sometimes contribute toward your closing costs, depending on the loan program.

What's the difference between a calculator estimate and a pre-approval?

A calculator gives you an estimate. A pre-approval gives you a verified number sellers trust. During pre-approval, a Brown loan advisor reviews your credit, income, assets, and debts, then issues a letter stating how much you're approved to borrow. Self-employed income, gift funds, a home you still need to sell, or seasonal earnings can change your number in ways no calculator can model. Get pre-approved before you start touring so your offer is ready the day you find the right house.

A free pre-approval replaces estimates with verified figures, and gives you a letter you can attach to an offer.
