# Southborough Gross Rental Yields: Can Rent Cover the Purchase Price?
Key Takeaways
•The direct answer: At a $980,000 purchase price, using Zumper's and Apartments.com's Southborough rent figures, gross rental yield (annual rent divided by purchase price, before expenses) runs about 3.0% to 4.1%. At the $1,200,000 single-family median, it is about 2.5% to 3.4%.
•The myth: The "right tenant" fixes the math. It doesn't. You have two levers: the rent ceiling — the most tenants in town will actually pay — which you cannot move, and the price you pay, which you can.
•The reality: Rent alone won't carry a Southborough purchase at these prices. Whatever return you expect has to come from price growth, and that assumption is yours to defend, not ours to assert.
•The bottom line: If a deal needs rent to carry it, pay less for the property or buy elsewhere.
Why Won't a Southborough Home Cash Flow on Rent Alone?
Say you're looking at a Southborough house listed near $980,000. Here is what the town's rents will actually pay you on that price. Everything below is gross yield: rent before any expense.
As of September 15, 2026, Zumper reports Southborough's median rent at $2,465 per month. Apartments.com shows September 2026 average rents of $2,700 for a one-bedroom and $3,386 for a two-bedroom. Even the strongest two-bedroom rent in town tops out near $3,386 a month. That is the most the market will pay you against a near-seven-figure price.
What Is the Gross Rental Yield on a $980,000 Property?
•Base case: $2,465 × 12 = $29,580 ÷ $980,000 = 3.02% gross
•Higher-rent case: $3,386 × 12 = $40,632 ÷ $980,000 = 4.14% gross — an apartment average, the best stand-in we have for the strongest rent in town, not a measured single-family rent
These figures come before tax, insurance, repairs, vacancy, management, leasing costs, and mortgage interest. Net cash flow will be far lower, and rent probably will not cover the full monthly cost.
$980,000 is also a price below what most Southborough houses actually sell for. MLS PIN data puts the median sold price for single-family homes at $1,200,000. At that median, the same rents yield 2.47% to 3.39% gross.

The snapshot also carries the exit story: 3.1 months of supply for houses against 5.3 months for condos — meaning at the current sales pace, that is how long it would take to sell every listed home of each type.
What Are the Strongest Arguments Against This?
"Gross yield is the wrong metric. I'm buying leveraged appreciation."
Valid — you're buying equity and the loan balance your tenant helps pay down. But that makes the price assumption the one you have to defend. Run your return at 0%, 2%, and 4% annual price change, and see which ones still work. The rent side is already fixed near 3.0%–4.1% gross. Niche puts median household income for the Southborough school district near $196,808. Buyers with that income are competing for these houses to live in, and they don't need the rent to pencil — which is why prices stay above what an investor's math supports.
"A detached house rents for more than a two-bedroom apartment."
The strongest objection. A house may rent above apartment averages. But the tenant's documented alternative is $3,386 for a two-bedroom, and house rents can only separate so far before a renter takes the cheaper option.
"The median sale price is too broad."
Correct — for single-family. A few luxury or teardown sales move the $1,200,000 median, and the medians split by type: houses $1,200,000, all property types together $1,190,000, condos $640,000. The town-wide number tracks houses, not condos.

| Median Sold Price | Mixed | $1,190,000 |

The condo median of $640,000 is the cheaper entry point the objection describes. At the $2,465 median rent: $29,580 ÷ $640,000 = 4.62% gross, against 3.02% at $980,000. Condos also sit longer — 5.3 months of supply against 3.1 for houses — so the yield advantage comes with a slower exit. Or work backward: to hit 5% gross on $29,580 of rent, buy near $592,000.
Who Should Still Write the Check?
Southborough fits a long-hold investor, a buyer who may live in the home first and rent it later, or a portfolio where this town supplies stability while other properties supply cash flow.
One planning note: ask your agent who pays the leasing agent's fee under current Massachusetts rules, and budget the cost either way.
Don't buy here expecting rent to do the work. Buy only if you can afford the monthly gap and you have your own reason to believe prices here keep rising. Before you write an offer, ask for comps — recent sale and lease prices for similar nearby homes — on the exact street. Town-wide medians are a starting point, not a plan.
