The Question Every Buyer Should Ask First
Before you start scrolling through listings or booking open house tours, there’s one question you need to answer honestly: How much house can I actually afford?
Notice the word “actually.” Online mortgage calculators will happily spit out a number based on your income alone – but real affordability is more nuanced. It involves your debts, your lifestyle, your savings, your job stability, and yes, your comfort level with a monthly payment you’ll be making for the next 15 to 30 years.
This guide breaks it all down in plain language so you can walk into the homebuying process with a realistic number – not just an optimistic one.
Start with the 28/36 Rule
The 28/36 rule is one of the most widely used guidelines in mortgage lending, and it’s a great starting point for understanding affordability.
- 28% — Your monthly housing costs (mortgage principal, interest, property taxes, and homeowner’s insurance — known as PITI) should not exceed 28% of your gross monthly income.
- 36% — Your total monthly debt payments (housing costs plus car loans, student loans, credit cards, etc.) should not exceed 36% of your gross monthly income.
Example: If your gross household income is $8,000 per month, your max housing payment should be around $2,240, and your total monthly debts should stay under $2,880.
This is a useful starting benchmark, but lenders today often allow higher ratios depending on your loan type, credit score, and financial profile. FHA loans, for example, may allow a debt-to-income ratio (DTI) up to 50% in some cases.
What Is Debt-to-Income Ratio (DTI) and Why Does It Matter?
Your debt-to-income ratio (DTI) is one of the most important numbers lenders look at when evaluating your mortgage application. It measures how much of your gross monthly income goes toward paying debts.
How to calculate it:
- Add up all your monthly debt payments (minimum credit card payments, car loan, student loan, personal loan, etc.)
- Add your estimated new monthly mortgage payment.
- Divide the total by your gross monthly income.
- Multiply by 100 to get a percentage.
Example:
Monthly debts: $400 (car) + $200 (student loan) + $150 (credit card) = $750
Estimated mortgage: $1,800
Total: $2,550
Gross monthly income: $7,500
DTI = $2,550 ÷ $7,500 = 34%
Most conventional loans prefer a DTI under 43–45%. FHA loans may go up to 50%. The lower your DTI, the better your loan terms will typically be.
Beyond the Mortgage Payment: Real Costs of Homeownership
One of the biggest mistakes first-time buyers make is budgeting only for the mortgage payment. Homeownership comes with a full set of ongoing costs that renters don’t face. Here’s what you need to factor in:
Property Taxes
Property taxes vary significantly by location. In New Jersey, for example, property taxes are among the highest in the country — averaging over $9,000 per year in many counties. In Florida or Texas, rates may be lower but still substantial. Always research the specific tax rate for the town or county you’re buying in, not just the state average.
Homeowner’s Insurance
Lenders require homeowner’s insurance, and the cost depends on your location, home value, and coverage level. Budget anywhere from $1,000 to $3,000+ per year depending on your market.
HOA Fees
If you’re buying a condo, townhouse, or home in a planned community, you may owe monthly or annual HOA (Homeowners Association) fees. These can range from $100 to $1,000+ per month and are factored into your DTI by lenders.
Maintenance and Repairs
A common rule of thumb is to budget 1% of your home’s purchase price per year for maintenance and repairs. On a $400,000 home, that’s $4,000 annually — or roughly $333 per month. Older homes or properties with aging systems (roof, HVAC, plumbing) may require more.
Utilities
Homeowners typically pay more in utilities than renters — especially for heating, cooling, water, and trash. Ask the seller for past utility bills to get a realistic estimate before you buy.
PMI (Private Mortgage Insurance)
If your down payment is less than 20% on a conventional loan, you’ll pay PMI until you reach 20% equity. PMI typically costs between 0.5% and 1.5% of the loan amount annually — on a $350,000 loan, that could be $145 to $438 per month added to your payment.
How Much Do You Need Saved Before Buying?
Your savings picture matters just as much as your income. Here’s what you need to have ready:
- Down payment: As low as 3% (conventional), 3.5% (FHA), or 0% (VA/USDA) — though 20% avoids PMI.
- Closing costs: Typically 2–5% of the loan amount. On a $400,000 purchase, expect $8,000–$20,000 in closing costs.
- Cash reserves: Most lenders want to see 2–6 months of mortgage payments in savings after closing — this shows you can handle financial bumps.
- Move-in costs: Moving expenses, new furniture, immediate repairs, and any appliances the home doesn’t include.
Bottom line: even with a low down payment loan, you’ll likely need at least 5–7% of the purchase price in liquid savings to cover all upfront costs comfortably.
The Lifestyle Factor: What Can You Comfortably Afford?
Lenders will tell you the maximum you qualify for. That’s not always the same as what you should spend.
Ask yourself these questions before committing to a number:
- Do you plan to have children or expand your family soon?
- Are you saving for retirement or other major goals?
- Do you value travel, dining out, or other lifestyle spending?
- How stable is your income? Are you in a salaried role or commission-based?
- Do you have an emergency fund beyond your down payment savings?
A payment that technically “fits” your DTI may still leave you feeling house-poor — stretched so thin that you can’t enjoy your home or handle unexpected expenses. A good mortgage advisor will help you find the sweet spot between what you qualify for and what makes sense for your life.
A Simple Affordability Framework
Here’s a practical way to think about it:
- Take your gross monthly income and multiply by 0.28 — that’s your target max housing payment (PITI).
- Subtract your estimated property taxes and insurance — what’s left is roughly your maximum principal + interest payment.
- Use a mortgage calculator to see what loan amount that payment corresponds to at current interest rates.
- Factor in your down payment to determine your target purchase price range.
- Sanity check against your lifestyle budget — does that payment leave room for savings, emergencies, and the things you enjoy?
This won’t give you a perfect number, but it gives you a grounded starting range — much better than guessing based on a listing price you liked.
How a Mortgage Broker Can Help You Find Your Number
Online calculators are a starting point, but they don’t account for your full financial picture, the loan programs available to you, or the local market you’re buying in. A licensed mortgage broker can:
- Review your actual income, debts, and credit profile.
- Match you with loan programs that fit your situation (FHA, conventional, NON-QM, VA, and more).
- Give you a real pre-approval amount – not a guess.
- Help you understand the total monthly cost of homeownership in the area you’re targeting.
- Identify ways to improve your buying power before you apply.
