While browsing rental listings in the evening, I calculated the potential income from a rental property in Hagerstown from start to finish.

The home prices are definitely low, but the rent is also low, which makes it a bit ambiguous.

In such areas, you can't just say it's cheap based on home prices alone, nor can you easily judge profitability based solely on rent.

According to RentCafe data, the average rent for apartments in Hagerstown is about $1,537 per month in 2026.

This is a 3.28% increase from a year ago. The average home value, according to Zillow, is about $304,000.

So let's do a simple calculation.

If you receive $1,537 in rent for a year, that totals $18,444. Dividing this by the home price of $304,000 gives you about 6.1%. This is the simplest way to look at the total return rate.

Not bad, actually. Since home prices are low in Hagerstown, even if the rent isn't very high, the rent-to-purchase price ratio turns out to be decent.

However, 6.1% is not the actual return rate that ends up in my pocket.

When renting out a house, property taxes and insurance costs come into play, and there will also be repair costs. After a tenant leaves, the house might be vacant for a month or two.

Let's apply the 50% rule simply. This method assumes that about half of the annual rental income of $18,444 goes to operating expenses.

Then the net operating income would be about $9,222.

If you divide this amount by the home price, the cap rate is about 3%.

The initial 6.1% and the 3% that takes actual costs into account feel quite different.

So when looking at real estate return calculators, you shouldn't just trust the big number displayed on the screen.

What's interesting about Hagerstown is that the property tax burden is relatively low. The median property tax rate in Washington County is known to be about 0.88%, and the median annual property tax is about $2,083. Since home prices are low, the actual taxes paid are less burdensome compared to more expensive areas in Maryland.

However, not all numbers are favorable.

Applying the 1% rule commonly discussed in real estate investing, a $304,000 house should generate about $3,040 in rent per month. Compared to the average rent of $1,537 in Hagerstown, this is only about half. Finding a house that meets the 1% rule in today's market is not easy, but at least by this standard, it's hard to say it's a market that generates outstanding rental income.

You also shouldn't rely on just one rental data point. Depending on the source, the average rent in Hagerstown can be reported around $1,400.

While $1,400 and $1,537 may not seem like a big difference, the return rate changes when calculated over a year. Ultimately, the most important thing is to check how much similar-sized and conditioned homes are renting for in the area where you plan to buy.

The advantage of Hagerstown is the entry cost. Compared to homes priced at $500,000 to $700,000, even with the same 20% down payment, the initial cash outlay is much lower. So if the loan conditions are favorable, it's worth considering the cash-on-cash return based on the actual cash invested.

However, I view Hagerstown a bit differently than a market where I expect home prices to rise significantly. Rather than anticipating strong commuting demand and high home price appreciation like areas close to Washington D.C., I find it easier to understand as a market where you can buy homes relatively cheaply and steadily receive rental income focused on cash flow.

Ultimately, what matters is not "Wow, a house in Hagerstown is only $300,000." It's about how much you can rent that house for, how much property tax and insurance costs are, and how much is left after accounting for repairs and vacancies.

Just because home prices are low doesn't mean it's a good investment, and just because rent is low doesn't mean it's a bad investment. In markets like Hagerstown, where both home prices and rents are low, the most important number is ultimately how much is left in my bank account at the end.
