Buyer Education · September 8, 2026 · 7 min read
Last Tuesday at an open house in Bel Air, a woman in her early thirties walked through twice. The second time, she lingered at the kitchen island. "I pay $1,850 for a two-bedroom in Edgewood," she said. "This place is listed at $329,000. The mortgage calculator says maybe $2,400 a month. Am I crazy to even think about it at these rates?"
I wasn't going to lie to her. That's a $550 monthly gap, and it's real money.
But I also wasn't going to let her walk away thinking the math stops there. So I grabbed the listing flyer, flipped it over, and we did what I do with a lot of renters in Harford, Cecil, and Baltimore County these days: we sketched out the break-even clock.
Not the fantasy version where home prices double every five years. The boring, honest version that accounts for closing costs, maintenance, tax benefits, and the fact that your landlord raises rent and you don't.
Most people compare monthly rent to monthly mortgage payment and stop. That's like comparing a gym membership to a barbell: one builds equity, the other disappears.
When I taught high school economics in Baltimore County, I used to tell students that renting is paying someone else's mortgage. That's still true. But buying isn't free money either. There are transaction costs. Repairs. The reality that you can't just text the landlord when the water heater dies at 9 p.m. on a Sunday.
The smarter question isn't "which is cheaper per month?" It's "how long until I break even on the upfront costs of buying, and does that timeline fit my life?"
Break-even is the point where the total cost of owning equals what you would have spent renting and keeping your down payment invested elsewhere.
It includes:
Then you subtract:
The year those numbers cross is your break-even year. Before that, renting was cheaper. After that, you're ahead.
Let's use that Harford County buyer as a case study. She's looking at a $329,000 home. That's right around the median for homes for sale in Harford County in late 2026.
Here's what the first five years look like if she puts 5% down ($16,450) with a 6.71% rate:
Year 1:
Her rent? $1,850. But her landlord just renewed leases at 4% higher for 2027. That's $1,924.
By year three, if rent keeps climbing 3–4% annually (the 20-year average for the Baltimore metro according to HUD data), she's paying over $2,050 in rent. Her net ownership cost? About the same, but she's built roughly $18,000 in equity and her mortgage payment hasn't moved.
Break-even in this scenario: 4.2 years.
If she stays seven years (the national average), she's about $35,000 ahead, assuming 2% annual appreciation and rent growth at 3.5%. Not a fortune, but not nothing.
Break-even stretches or snaps if:
I'm a Maryland realtor working in eight counties, DC, and parts of Pennsylvania and Delaware. I've run these numbers dozens of times in the past six months. Here's the pattern:
Harford, Cecil, and Baltimore County: Break-even typically lands between 3.5 and 5 years, depending on price point. Median home prices are manageable, tax rates are moderate, and rent growth in towns like Bel Air, Havre de Grace, and Edgewood has been steady.
Anne Arundel and Howard Counties: Break-even stretches to 4–6 years. Higher home prices mean bigger down payments and closing costs, but job stability and schools keep demand high. Rent growth is strong.
Montgomery and Prince George's Counties: 4.5–6.5 years. Closer to DC, higher prices, but also higher rent. If you're planning to stay near the metro, the math works. If you're on a two-year contract job, it doesn't.
DC proper: Honestly? Six to eight years, sometimes longer. Closing costs are higher (D.C. has a recordation tax and transfer tax that add up), condo fees are real, and rent control complicates the equation. But if you're staying, it's still better than paying a landlord forever.
York and Lancaster Counties, PA, and New Castle County, DE: Break-even can be as short as 3–4 years. Prices are lower, taxes vary (Pennsylvania has no local income tax but higher school taxes; Delaware has no sales tax but transfer taxes). If you work remote or commute to Maryland, these markets deserve a look.
When someone asks me "should I buy or keep renting?", I ask three questions:
The break-even model is a tool. It's not a crystal ball. I've had buyers break even in 18 months because they bought in a hot zip code and got lucky. I've had others take seven years because they bought during a plateau. Real estate is local, and timing is personal.
You don't need fancy software. Freddie Mac has a rent-vs-buy calculator that's pretty solid. Plug in your local rent, the home price you're considering, your down payment, current rates, and how long you plan to stay.
Or call a Maryland realtor (like me) and ask us to walk through it. We do this all the time. If the answer is "keep renting for now," I'll tell you. My job is to teach, not to talk you into a bad decision.
If you're ready to look at homes for sale in Baltimore County, Harford, or anywhere in the metro, let's start with the math. Then we'll find the house.
That woman at the open house in Bel Air? She didn't make an offer that day. But she took the napkin with her. Two days later, she emailed me her credit report, tax returns, and a list of questions about closing costs.
We're running a full break-even analysis this week. She might buy. She might wait six months. Either way, she'll know the real numbers, not the fairy tale.
That's what I did for 20 years in education, and it's what I do now. Numbers don't lie, and neither do I.
If you want to run the math for your situation, let's talk. I've got more napkins.
