One of the most common questions investors ask when buying a vacation rental home is simple:
how big should it be? The right answer depends on your budget, your target guest, and how you plan
to perform not only in peak summer weeks, but also in the shoulder seasons.
In coastal, seasonal markets like Cape Cod, Martha’s Vineyard, and Nantucket—and in beach
destinations nationwide—size affects everything from nightly rates and booking appeal to operating
costs like cleaning, utilities, and maintenance.
Start with your goals and your ideal guest
Before you decide on square footage, get specific about who you’re trying to attract. Are you aiming for
multi-generational family groups, two families traveling together, couples, or a mix? Your ideal guest will
determine the bedroom count, bathroom needs, and how important separate living areas are.
Bedrooms: 3 vs. 4 (and why primary suites matter)
Your budget and your goals will largely determine the size of the home you buy. In general,
four-bedroom homes rent for more than three-bedroom homes, especially when two of those bedrooms can
function as primary suites.
That kind of layout makes it easy for two small families to share a home and split the cost, which
is very appealing to many renters. Homes that sleep a group comfortably—without forcing everyone to share a single
hallway bath—tend to feel more “vacation-ready.”
If you’re considering a larger home, pay attention to bedroom placement and privacy (for example, a
first-floor suite plus a separate bedroom wing) because layout often matters as much as bedroom count.
Bathrooms: a major decision-maker for groups
The number of bathrooms matters, too. Even a modest two-bedroom cottage becomes much more attractive if it offers
two bathrooms, or at least one full bath and one half bath.
From an investor’s perspective, bathrooms are one of the most practical “comfort upgrades” you can buy: they reduce
guest friction during the morning rush, make shared stays easier, and help support higher occupancy without the home
feeling cramped.
Common space: give guests room to spread out
Homes with both a living room and a separate family room give guests welcome options for spreading out, and features
like sunrooms and screened porches are consistently popular.
This matters even more for weeklong stays. When it rains—or when kids want one thing and adults want another—having
separate spaces can be the difference between “tight quarters” and a home that feels easy to live in.
Seasonality: bigger isn’t always better
It’s also worth keeping seasonality in mind. Larger homes with four or more bedrooms tend to be harder to rent
during the shoulder seasons than smaller properties. In many coastal markets with weekly summer
rentals, peak demand is concentrated into a limited number of prime weeks, while spring and fall bookings are less
predictable.
A larger home can still be a strong investment, but it helps to underwrite realistically: bigger properties often
have higher operating costs (cleaning time, utilities, and maintenance), and you may need standout features or a
flexible layout to attract off-season demand.
Duplexes: flexibility when demand shifts
A duplex can offer excellent flexibility. It works well for two small families traveling together
who want some shared space but also value privacy.
During the off-season, when demand for larger homes drops, each side of the duplex can often be rented separately.
That can widen your renter pool and help smooth out seasonality.
If you’re evaluating a duplex, pay attention to practical details like sound separation, outdoor space boundaries,
parking, and whether each side has its own “must-have” features (a functional kitchen, comfortable living area, and
adequate bathrooms).
Accessory Dwelling Units: privacy and options
Homes with a separate living space, such as an apartment over a garage or a small cottage on the property, are
especially appealing to families who want a bit more privacy for certain members of their group—such as grandparents,
adult children, or a nanny.
From an investment standpoint, an ADU can also add flexibility. Depending on local rules and how
the property is configured, it may allow you to:
- Offer a “main house + guest suite” experience for larger groups
- Create separation that makes shared bookings more comfortable
- Appeal to smaller groups during the shoulder seasons by emphasizing a cozier footprint
As with any property featuring multiple living spaces, it’s important to confirm how the home can be used and
marketed under local guidelines (including occupancy, parking, and any applicable permitting).
Investor takeaway: match size to demand, not just peak-week potential
The best-performing vacation rentals are usually the ones that feel comfortable and intuitive for their target
guest. A larger home may command a higher rate in peak season, but a well-designed smaller home can be easier to
keep booked outside of summer and may come with lower operating costs.
When you’re deciding how big to buy, focus on a few high-impact questions:
- Who is the home for? (two families, one extended family, couples, mixed groups)
- Does the layout support privacy? (primary suites, bedroom separation, bathroom count)
- Can guests spread out? (multiple living areas, screened porch, sunroom)
- How will it perform in shoulder seasons? (flexible layout, ADU/duplex options)
- Do operating costs scale with size? (cleaning time, utilities, wear-and-tear)
FAQ: Vacation rental home size
Q: Is a four-bedroom vacation rental always a better investment than a three-bedroom?
A: Not always. Four-bedroom homes can earn higher peak-season rates, especially with two primary
suites, but they may be harder to book in shoulder seasons and often cost more to operate. Layout and flexibility
matter as much as bedroom count.
Q: How many bathrooms do renters expect?
A: For group stays, more bathrooms make a meaningful difference. Even in smaller homes, having two
bathrooms—or one full plus one half bath—can boost booking appeal and reduce guest friction.
Q: Do duplexes work well as vacation rentals?
A: Duplexes can perform very well because they offer built-in flexibility: they can accommodate
larger groups together in peak season and appeal to smaller groups by renting separately in the off-season.
Q: Are homes with ADUs worth it for vacation rental investors?
A: Often, yes—because ADUs add privacy and options. They can make larger group bookings more
comfortable and help broaden your appeal outside of peak weeks, depending on how the property is configured and
local guidelines.
