The modern second home: a sanctuary with a spreadsheet
In South Florida, the second-home conversation has matured. Since 2020, vacation and second homes have increasingly been positioned as investments, valued not only for personal enjoyment but also for potential appreciation and rental income. That reframing can be useful, but it also raises the bar: today’s buyer needs both a clear lifestyle point of view and an underwriting model built to survive imperfect seasons, shifting rules, and real carrying costs.
MILLION Luxury sees the cleanest outcomes when buyers name the primary objective early. If this is a second home you would keep even if rentals were restricted, you can shop patiently and prioritize qualities that compound over time: privacy, quiet, and ease of ownership. If the thesis depends on frequent renting, the property needs to be evaluated like a business, with conservative assumptions and operational realism at the center of the decision.
Start with the non-negotiables: time, spontaneity, and privacy
Before you debate cap rates, define how you will actually use the home. How many weeks will you be in residence, and how spontaneous do you want that access to be? High-occupancy short-term rental plans generally require more turnover, tighter calendars, and more coordination. The tradeoff is simple: maximizing revenue often reduces last-minute owner use and increases the ongoing attention needed to manage wear, tear, and service standards.
For buyers who want a hotel-adjacent experience without full-time responsibility, a condo-hotel style of ownership can feel intuitive, particularly when service and staffing are part of the value proposition. In Miami Beach, ultra-prime options are frequently evaluated through this lens, where daily convenience, discretion, and brand standards can matter as much as the view.
Consider how a buyer might weigh the service-forward positioning implied by Setai Residences Miami Beach against the quieter, residence-first sensibility many associate with 57 Ocean Miami Beach. The point is not which is “better.” It is which one matches your tolerance for staff interaction, your privacy expectations, and your preferred rhythm of arrivals and departures.
Financing reality: second homes are not underwritten like primaries
Even at the luxury tier, lenders commonly apply stricter standards to second homes than to primary residences. Buyers should expect larger down payments, commonly around 10 percent to 20 percent or more depending on borrower profile and lender, plus additional cash reserves.
In practice, your true cost to control is more than the purchase price. It includes the equity you must commit, the liquidity you need to keep accessible, and the carrying costs you must be willing to fund even when the home sits unused. If you intend to rent, stress-test your model with months of low or zero occupancy so the asset remains comfortable to hold.
This is where sophisticated buyers separate “can” from “should.” A second home can fit your balance sheet and still clash with your calendar. The strongest acquisitions are the ones you can hold without pressure and enjoy without resentment.
Rental economics: model the unglamorous line items
A credible rental plan starts with assumptions that are intentionally unexciting. Location drives demand, seasonality, and pricing power, and return potential can vary dramatically across South Florida submarkets. Industry outlook commentary also highlights that supply and demand shifts can pressure both occupancy and nightly rates, which makes it unwise to underwrite based on peak-year performance.
Build the model from the inside out. Treat professional management as a core expense, not an optional add-on. Vacation-rental management is commonly priced as a meaningful share of revenue. That reduces net income, but it can also turn ownership into something genuinely hands-off.
Then layer in the line items that rarely appear in aspirational pro formas: replenishment, repairs, deep cleans, small upgrades that protect reviews, and the opportunity cost of owner calendar restrictions. If your plan requires being “always rentable,” you are effectively choosing a managed hospitality asset. If that sounds like work, it is worth acknowledging up front.
For buyers drawn to Airbnb-style demand, the higher-level question is durability. Would the property remain desirable and financially tolerable if platform dynamics shift, if local enforcement tightens, or if your building’s policies change? Underwriting should include that downside case, even if you never expect to live in it.
Taxes: the line between “vacation home” and “rental” matters
Tax treatment hinges on how much you personally use the home relative to the days it is rented at fair rental value. A common rule of thumb is that if personal use exceeds the greater of 14 days or 10 percent of the days rented, the IRS may treat the property as a personal residence, which can limit deductible rental losses.
There are also edge cases that luxury buyers sometimes overlook. If you rent the home for fewer than 15 days in a year, the rental income generally is not reportable to the IRS, and related rental-expense deductions generally are not allowed. That can be appealing for occasional-event use, but it is not the same as running a rental business.
When a property is treated as a rental, owners generally report income and expenses on Schedule E and can typically deduct operating expenses plus depreciation, subject to tax rules and limits. Residential rental real estate is generally depreciated over 27.5 years, which can reduce taxable rental income even when cash flow is positive. However, depreciation is typically subject to recapture when the property is sold, often taxed at rates up to 25 percent for unrecaptured Section 1250 gain.
Finally, second-home itemized benefits are not unlimited. Many taxpayers contend with the $10,000 cap on state and local tax deductions and a mortgage-interest limit that applies to interest on up to $750,000 of acquisition indebtedness (for many taxpayers). The takeaway is not that taxes should drive the decision. It is that the after-tax picture should be understood before you commit.
Regulation and building rules: underwrite governance, not just the unit
Short-term rental restrictions and enforcement vary widely by city and by HOA, and they can change. Treat regulatory due diligence as a core part of the acquisition, especially if rentals are central to your plan.
In Miami Beach, practical friction is often as important as legal language: minimum stay rules, registration requirements, security and guest policies, elevator protocols, and the building’s tolerance for turnover. A well-run, service-oriented building can offer frictionless living for owners, but it may also be less compatible with frequent guest rotation.
If your objective is a residence with a hospitality-grade experience for you, not necessarily for guests, evaluate properties such as The Ritz-Carlton Residences® Miami Beach or Casa Cipriani Miami Beach through the lens of owner experience first: arrival, staff discretion, and how the building protects privacy. Consider rental optionality only after governance, rules, and culture are clear.
Alternatives to full ownership: when flexibility is the luxury
If expected personal use is low, full ownership can be an expensive way to buy a feeling. Co-ownership is one alternative that can lower the cost of a second home, but it requires a clear agreement on scheduling, expenses, governance, and exit terms. Other rent-versus-buy comparisons often come down to how frequently you will use the home and whether rental income is realistic after expenses and effort.
For some buyers, the most refined approach is to keep liquidity flexible and rent with intention, reserving ownership for a property that is truly irreplaceable to their lifestyle. The underlying question is simple: are you buying access, or are you buying identity? When it is identity, ownership tends to age well.
A Miami Beach case study mindset: matching asset type to how you live
Miami Beach is not one market; it is a series of micro-decisions about noise, walkability, privacy, and how you want to feel on a Tuesday morning. An oceanfront residence that prioritizes quiet and architecture supports a different lifestyle than a more social, event-adjacent address.
A buyer drawn to cultural proximity and design-forward living might naturally gravitate toward Faena House Miami Beach, where the surrounding neighborhood energy can be part of the ownership experience. Meanwhile, a buyer optimizing for decompression may weight setbacks, internal circulation, and how the building manages arrivals.
The discipline is to translate those preferences into underwriting. If the home is a sanctuary, model rentals as a modest offset, not the core rationale. If the home is a managed rental asset, accept that it will behave like one, and choose a building where governance and operations support that reality.
FAQs
How do I decide if this is a lifestyle buy or an investment? Write down your top three non-negotiables for use, then model returns assuming rentals are limited. If you still want the home, lifestyle leads.
Are second-home down payments typically higher? Yes. Buyers often face higher down payment expectations than primary residences, commonly around 10 percent to 20 percent or more depending on the lender and profile.
What is the key IRS threshold for personal use? A commonly referenced threshold is the greater of 14 days or 10 percent of the days rented at fair rental value, which can affect whether it is treated as a residence.
What happens if I rent the home fewer than 15 days? Generally, the rental income is not reportable to the IRS, and related rental-expense deductions are generally not allowed.
If it is treated as a rental, what tax forms are typical? Rental income and expenses are generally reported on Schedule E, subject to applicable rules and limits.
Can depreciation reduce taxable rental income? Often, yes. Residential rental real estate is generally depreciated over 27.5 years, which can reduce taxable income even if cash flow is positive.
What is depreciation recapture? When you sell, depreciation is typically recaptured, often taxed up to 25 percent for unrecaptured Section 1250 gain.
Why do I need conservative occupancy assumptions? Because supply and demand shifts can pressure both occupancy and nightly rates. Modeling a down year helps protect you from overpaying.
How significant is professional property management cost? It is commonly priced as a meaningful share of revenue, which can reduce net income while making ownership more hands-off.
Is co-ownership a credible alternative? Yes, when documented carefully. The agreement should clearly define scheduling, expenses, governance, and exit terms.
