How Much House Can I Afford in South Jersey? Complete Guide for 2026

The short answer: with a typical household income in Burlington County, you can likely afford a home between $280,000 and $550,000, depending on your down payment, debt, credit score, and the town's property tax rate. But the real answer depends on your specific financial picture and the South Jersey town you choose.

"How much house can I afford?" is the first question every buyer asks. It is also the most important one to get right. Overestimate and you stretch yourself thin. Underestimate and you leave options on the table that could have worked.

In this guide, I will walk you through exactly how lenders calculate affordability, how South Jersey's unique property tax landscape changes the math, and what you need to know to shop with confidence in Burlington County and beyond.

The 28/36 Rule Explained

Lenders use two key ratios to determine how much house you can afford. Together, they are called the 28/36 rule, and they have been the standard for mortgage underwriting for decades.

Front-End Ratio (28%)

Your front-end ratio, also called the housing ratio, measures your total monthly housing costs against your gross monthly income. It includes principal, interest, property taxes, and homeowners insurance (PITI), plus any HOA fees or mortgage insurance.

The rule: Your total monthly housing payment should not exceed 28% of your gross monthly income.

• If you earn $80,000 per year ($6,667/month), your max monthly housing payment is about $1,867
• If you earn $100,000 per year ($8,333/month), your max monthly housing payment is about $2,333
• If you earn $120,000 per year ($10,000/month), your max monthly housing payment is about $2,800

Back-End Ratio (36%)

Your back-end ratio, also called the debt-to-income ratio (DTI), includes all of your monthly debt obligations: your housing payment plus car loans, student loans, credit card minimum payments, personal loans, child support, and any other recurring debts.

The rule: Your total monthly debt payments should not exceed 36% of your gross monthly income.

Some loan programs allow DTI ratios up to 43% or even 50% with strong compensating factors (high credit score, significant reserves), but 36% is the conventional benchmark and the safest target to ensure you maintain financial flexibility.

Why Lenders Use These Ratios

Lenders are not being arbitrary. Decades of mortgage performance data show that borrowers whose housing costs exceed 28% of income, or whose total debt exceeds 36%, are statistically more likely to fall behind on payments. These ratios protect you as much as they protect the lender.

That said, these are guidelines, not hard limits. A strong credit score, a large down payment, or substantial cash reserves can allow you to qualify with higher ratios. The key is knowing where you stand before you start looking at homes.

How Lenders Calculate Your Income

Not all income is treated equally. Lenders need to verify that your income is stable and likely to continue. Here is how different income types are evaluated.

W-2 Employees

If you receive a regular paycheck with a W-2 each year, you are in the simplest category. Lenders typically use your gross annual salary or hourly wage. If you are paid hourly, they may average the most recent two years. Overtime and bonus income can be included if it has been consistent for at least two years.

Self-Employed Borrowers

Self-employed borrowers face more scrutiny. Lenders will review two years of tax returns and use your adjusted gross income (AGI), which means your business deductions reduce your qualifying income. This is a common surprise for self-employed buyers who show strong revenue but low taxable income after write-offs.

If you are self-employed and planning to buy, work with a CPA or tax professional who understands mortgage qualifying. Sometimes it makes sense to reduce certain deductions in the year before you apply.

Commission Income

Real estate agents, sales professionals, and others with commission-based income will need a two-year history. Lenders average the most recent two years and may require that the income shows an upward or stable trend. A down year can hurt your buying power, even if the current year is strong.

Dual-Income Households

If both partners work, both incomes generally count toward your qualifying amount, as long as the income is documented and stable. If one partner is starting a new job, most lenders require a 30-day history before counting that income. If one partner is a gig or contract worker, the same self-employment rules apply.

Keep in mind that if one partner plans to stop working after the purchase (for example, to stay home with children), a lender will typically not count that income unless there is a documented return-to-work plan.

Debt-to-Income Ratio: What Counts and How to Improve It

Your DTI is one of the most important numbers in your mortgage application. Here is what counts and what does not.

What Counts as Debt

• Credit card minimum payments (not your full balance, just the minimum due)
• Auto loans and leases
• Student loans (even if deferred, lenders often use 0.5% to 1% of the balance as the monthly payment)
• Personal loans
• Child support and alimony (if court-ordered)
• Other mortgage or real estate obligations

What Does Not Count

• Cell phone bills
• Utilities
• Netflix and subscription services
• Insurance premiums (except homeowners insurance, which is part of PITI)
• Groceries and living expenses

Ways to Improve Your DTI

• Pay down credit card balances (even paying $1,000 off a card can lower your minimum payment and improve your DTI)
• Pay off a car loan or personal loan before applying
• Avoid taking on new debt in the months before your application (no new car, no furniture financing)
• Increase your income through overtime, a second job, or freelance work (documented for two years)
• Consider a co-borrower with strong income and low debt

Down Payment Impact: Scenarios and PMI Costs

Your down payment size affects more than just how much cash you bring to closing. It changes your monthly payment, your interest rate, whether you pay PMI, and how competitive your offer is.

Down Payment Scenarios for a $400,000 Home

* Estimated monthly payment includes principal, interest (assumed 6.5% rate), property taxes (assumed 2.2% of value), and homeowners insurance. Actual amounts vary by town, credit score, and rate. **FHA MIP is required for the life of the loan.

What Is PMI and How Does It Work?

Private Mortgage Insurance (PMI) protects the lender if you default on your loan. It is required on conventional loans when your down payment is less than 20%. The cost typically ranges from 0.3% to 1.5% of the loan amount per year, depending on your credit score and down payment size.

The good news: PMI on conventional loans automatically cancels once your loan balance reaches 78% of the home's original value (or you can request cancellation at 80%). FHA loans have mortgage insurance premiums (MIP) that last for the life of the loan unless you put 10% or more down, in which case it drops off after 11 years.

South Jersey Affordability: Town-by-Town Breakdown

Here is where South Jersey gets specific. Property taxes vary dramatically by town, and that means two homes at the same price point can have very different monthly payments.

Median Home Prices and Income Needed (Q2 2026)

* Estimated monthly payment: principal + interest (6.5% rate), property taxes, homeowners insurance. 10% down assumed. Income needed based on 28% front-end ratio. For a personalized calculation, speak with a local lender.

The Property Tax Factor

New Jersey has the highest property taxes in the nation. Burlington County's average effective tax rate is approximately 2.4% of assessed value, but it varies significantly. In Willingboro (2.9%), you pay nearly $700 more per year per $100,000 of value than in Moorestown (2.18%).

This means a $400,000 home in Moorestown might have a lower monthly payment than a $350,000 home in a higher-tax town, depending on your down payment and interest rate. Always compare the total monthly cost, not just the purchase price.

For a deeper look, see our property taxes guide and Burlington County property taxes breakdown.

Hidden Costs Every South Jersey Buyer Should Budget For

The purchase price is just the beginning. Here are the costs that surprise many first-time buyers in South Jersey.

Property Taxes

As noted above, New Jersey property taxes add $600 to $1,200 per month to your mortgage payment on a typical home. This is the single biggest factor that changes affordability from town to town. Always get the exact tax amount on a specific property before making an offer.

Homeowners Insurance

Expect to pay $800 to $1,800 per year for homeowners insurance in South Jersey, depending on the home's age, construction, location (flood zones add significant cost), and coverage level. Flood insurance is separate and can cost $700 to $2,500 per year in flood-prone areas near the Delaware River or Rancocas Creek.

HOA Fees

Many South Jersey communities have homeowners associations, especially townhome and condo developments. Fees range from $100 to $400 per month. In Medford Lakes and some active adult communities, fees can be higher but often include amenities like pools, lakes, and landscaping.

Maintenance and Repairs

Budget 1% to 2% of your home's value per year for maintenance. On a $400,000 home, that is $4,000 to $8,000 annually. This covers everything from a new water heater ($1,200) to roof replacement ($8,000 to $15,000). Older homes in historic towns like Riverton or Burlington City may need more, while newer construction in Mount Laurel or Marlton may need less.

Closing Costs

Closing costs in New Jersey typically run 2% to 5% of the purchase price. For a $400,000 home, that is $8,000 to $20,000. These include lender fees, title insurance, attorney fees, recording fees, and prepaid items like property taxes and homeowners insurance.

See our complete guide to closing costs in New Jersey for a detailed breakdown.

Utilities

PSE&G (electric and gas) for a typical single-family home in Burlington County runs $200 to $400 per month. Water and sewer add another $50 to $150. Older homes with less insulation or older HVAC systems cost more to heat and cool.

7 Ways to Afford More Home in South Jersey

If the numbers above feel tight, do not lose hope. There are several strategies that can increase your buying power or reduce your upfront costs.

1. NJHMFA Down Payment Assistance

The New Jersey Housing and Mortgage Finance Agency offers down payment assistance programs for eligible first-time buyers. The NJHMFA First Generation Down Payment Assistance Program provides up to $15,000 in a forgivable, zero-interest loan. It does not need to be repaid if you stay in the home for five years. Combined with an FHA or conventional loan, this can dramatically reduce your cash-to-close.

Read our full guide to New Jersey down payment assistance programs.

2. Seller Concessions

In many transactions, the seller can agree to pay a portion of your closing costs. Conventional loans allow seller concessions of up to 3% of the purchase price (with less than 10% down) to 9% (with 25% or more down). FHA loans allow up to 6%. For a $400,000 home, a 3% concession puts $12,000 back in your pocket for closing costs.

Learn more about seller concessions and how they work.

3. Rate Buydowns (Temporary or Permanent)

A rate buydown lowers your interest rate for the first one to three years (temporary) or for the life of the loan (permanent). In a temporary buydown, the seller or builder typically funds the buydown by paying points at closing. A 3-2-1 buydown reduces your rate by 3% in year one, 2% in year two, and 1% in year three.

This can make your first few years of payments significantly more affordable and is especially useful if you expect your income to increase over time.

4. Adjustable-Rate Mortgages (ARM)

ARM loans offer a lower initial interest rate for a fixed period (typically 5, 7, or 10 years), after which the rate adjusts based on market conditions. A 7/6 ARM might be 1% lower than a 30-year fixed rate, which can save you $250 per month on a $400,000 loan.

ARMs are a good option if you plan to move or refinance before the adjustment period ends. They carry risk if rates rise significantly, so understand the terms before committing.

5. Look at Lower-Tax Towns

As the table above shows, towns with lower tax rates can save you hundreds per month compared to higher-tax municipalities at the same price point. Moorestown (2.18%) vs Willingboro (2.90%) on a $400,000 home is a difference of about $240 per month, or nearly $2,900 per year.

6. Improve Your Credit Score

A higher credit score gets you a lower interest rate. On a $400,000 loan, the difference between a 680 score and a 760+ score can be 0.5% to 0.75% on your rate, which translates to $120 to $180 per month in savings and $40,000 to $65,000 in interest over the life of the loan.

7. Get Pre-Approved Before You Shop

Pre-approval tells you exactly how much house you can afford and shows sellers you are a serious buyer. In a competitive market, pre-approved buyers have a significant advantage over pre-qualified or unqualified buyers.
