Quick Answer

How much do you need to earn?

With a 20% down payment and an interest rate around 6.5%, you typically need a household income between $70,000 and $80,000 to comfortably afford a $250,000 home【785758658480776†L140-L156】. This range keeps your monthly housing costs—including principal, interest, property taxes and insurance—under the recommended 28% of gross income and your total debt payments below 36%【785758658480776†L140-L156】. If you secure a lower interest rate or pay a larger down payment, you may qualify with an income closer to $65,000【785758658480776†L151-L154】. Higher rates or a smaller down payment will push the required salary closer to $85,000【785758658480776†L152-L156】. Use the 28/36 rule as a guideline and adjust for your debt load, credit score and local tax rates to determine your exact target.

Affordability rules

The 28/36 rule and debt‑to‑income

Lenders use the 28/36 rule as a benchmark. It suggests that you should spend no more than 28% of your gross monthly income on housing costs and no more than 36% on total debt obligations. Housing costs include mortgage principal and interest, property taxes, homeowners insurance and any private mortgage insurance (PMI). Total debt includes credit cards, car loans and student loans. If you gross $80,000 per year ($6,667 per month), 28% translates to about $1,867 per month. Keeping your housing payment under that figure ensures you have room in your budget for other expenses and savings. The debt‑to‑income (DTI) ratio is crucial: lenders typically want to see a DTI below 36%【785758658480776†L168-L181】. Managing existing debts and improving your credit score can lower your required salary.

Interest rates and down payment

How rates and cash change the equation

The interest rate on your mortgage and the size of your down payment dramatically affect how much you need to earn. In Better.com’s example, a 20% down payment ($50,000) at 6.5% interest results in a principal and interest payment around $1,265 per month【785758658480776†L145-L149】. Add taxes and insurance and your housing cost rises to roughly $1,600–$1,800 monthly【785758658480776†L145-L148】. To stay within 28% of gross income, you need to earn about $70,000–$80,000【785758658480776†L145-L156】. If you can put down more than 20%, your loan balance shrinks and monthly payments drop, meaning you can qualify with a lower salary. Conversely, a smaller down payment triggers PMI and increases monthly costs. Your credit score also influences your rate: excellent credit could lower your rate to 5.5%, reducing the required income to around $65,000【785758658480776†L151-L154】. Higher rates push the salary requirement toward $85,000【785758658480776†L152-L156】.

Examples & scenarios

Salary scenarios for a $250k home

Let’s examine a few scenarios. These examples assume property taxes and insurance of about $300 per month, typical for many parts of South Carolina, and PMI of $100 when applicable. Use them as ballpark estimates; your personal costs may differ.

These scenarios illustrate how a lower rate or larger down payment gives you more buying power. But they also show that even with minimum down payment programs, you need a solid income and low debt to comfortably afford a $250k home. Use a mortgage calculator and speak with a lender for personalized numbers.

Local considerations

Columbia & South Carolina context

In Columbia, home prices and taxes tend to be lower than national averages, but income levels also vary. The median household income in Columbia is about $57,568, while Lexington County’s median is $87,126【38305341806780†L441-L451】【809777497573567†L49-L58】. A $250,000 home may be more affordable in Lexington than downtown Columbia because residents typically earn more. Property taxes in Richland County average around $1,771 per year【38305341806780†L441-L451】, which is factored into the scenarios above. Insurance premiums may be higher near the coast or in flood zones. South Carolina’s Homestead Exemption for seniors can reduce taxes. When budgeting, account for regional differences in taxes, insurance and HOA fees. Also consider commuting costs and lifestyle expenses; the 28% rule is a guideline, not a strict limit. Some households may comfortably spend more if they have low debt or high savings.

Saving & credit tips

Preparing your finances

To meet salary and DTI requirements, start by paying down high‑interest debt and avoiding new loans. Check your credit reports for errors and work to improve your credit score; higher scores unlock lower rates【785758658480776†L169-L172】. Build a healthy down payment and emergency fund. In Columbia and Lexington, saving at least 10%–15% of the purchase price will help you cover closing costs and avoid excessive PMI. Consider state and federal programs for first‑time buyers or veterans that offer low‑down alternatives. Finally, get pre‑approved before house hunting so you know your exact budget and can act quickly when you find the right home.

Regional & long‑term outlook

Thinking beyond the monthly payment

Affordability isn’t just a mortgage calculation—regional factors and future market conditions matter. Property taxes and insurance vary widely across the U.S. In Texas and New Jersey, property taxes can exceed 2% of assessed value annually, while in South Carolina they hover around 0.5% to 0.6%. States prone to hurricanes or wildfires require higher insurance premiums, which increases the income needed for the same priced home. Local utilities, HOA fees and commute costs also influence your budget. For example, living further from downtown may mean lower purchase prices but higher transportation expenses.

Also consider the trajectory of interest rates and your own career. Rates in 2026 are predicted to remain in the mid‑6% range, but they may fluctuate. If you lock in at 6.5% today and rates drop, you can refinance to reduce payments. If rates rise, you’ll be glad you bought sooner. Income growth, job stability and family plans should influence how much house you buy. Don’t buy at the top of your budget if you anticipate childcare expenses or a career change. A home is a long‑term investment; building equity takes time, and selling too soon can eat up gains due to transaction costs. Create a five‑to‑ten‑year plan and choose a home that fits your lifestyle now and in the foreseeable future.

Common mistakes

Where buyers go wrong

A common mistake is stretching your budget for a house you love and relying on future raises to afford it. Others forget to budget for maintenance, utilities and unexpected repairs. Some buyers max out credit cards or finance new cars before closing, raising their DTI and jeopardizing their loan approval. Failing to compare lenders can cost thousands over the life of your loan. Always read the fine print on adjustable‑rate mortgages and balloon loans. Stick to a realistic price range and leave room for emergencies.

Action plan

Steps toward affordability

1. Assess your finances. Calculate your monthly income and total debt payments. Use the 28/36 rule to determine a safe housing budget.

2. Improve your credit. Pay down revolving balances, correct errors and avoid new debt. Aim for a credit score of 700 or higher to qualify for better rates.

3. Save aggressively. Build a down payment and emergency fund. Consider side gigs or bonus savings to reach your goal.

4. Shop for lenders. Get pre‑approved by multiple lenders to compare rates, fees and loan programs. Ask about VA, USDA, FHA and conventional options.

5. Adjust expectations. If your salary falls below the typical range, consider smaller homes, different locations or co‑borrowing with a partner. Stay flexible and think long‑term.
