Analyzing Rental Cash Flows in Broward and Palm Beach Counties
Deciding where to place capital in South Florida residential real estate comes down to a clear comparison: short-term rentals (STR) versus long-term rentals (LTR). While South Florida's tourism drive draws high gross revenues for vacation rentals, higher operating expenses and localized regulations heavily impact net operating income (NOI).
At The Jamie Seneca Team, we evaluate real estate acquisitions through strict underwriting metrics: Cap Rate, Cash-on-Cash Return, Net Operating Income (NOI), and total capital outlay. Here is how investors should underwrite LTR versus STR performance across Broward County and Palm Beach County.
The Long-Term Rental (LTR) Model: Predictability and Low Expense Ratios
Long-term single-family homes and townhomes in markets like Fort Lauderdale, Plantation, Boca Raton, and Palm Beach Gardens offer steady occupancy and manageable operating expense ratios.
Underwriting an LTR investment typically requires factoring in an expense ratio of 35% to 40% of gross rental income.
- Gross Yields: Typically range from 6% to 8% based on acquisition prices.
- Operating Expenses: Include property taxes, insurance (windstorm and flood), property management (8%–10%), maintenance reserves (5%–8%), and capital expenditure (CapEx) reserves (5%).
- Cap Rates: Unleveraged net cap rates generally land between 4.5% and 5.5% depending on submarket asset class.
For example, a $600,000 single-family property renting for $3,800 per month generates $45,600 in gross annual revenue. Operating expenses at 38% total approximately $17,328 per year, producing a Net Operating Income (NOI) of $28,272 and an unleveraged Cap Rate of 4.71%.
The Short-Term Rental (STR) Model: High Gross Revenue, High Expense Ratios
Vacation rentals in coastal hubs such as Hollywood, Pompano Beach, or downtown West Palm Beach can achieve 1.5x to 2.0x the gross revenue of a long-term rental. However, expense ratios are significantly higher—often consuming 50% to 60% of gross revenue.
Underwriting an STR requires accounting for:
- Management Fees: Professional STR management runs between 18% and 25% of gross revenues, compared to 8%–10% for LTR.
- Turnover and Utilities: Landlords pay 100% of electric, water, high-speed internet, lawn care, pool maintenance, and consumable restocking.
- Occupancy Fluctuations: South Florida exhibits seasonality, with peak rates from December through April and lower demand during summer months. A realistic blended annual occupancy assumption is 65% to 72%.
- Upfront Capital Outlay: Furnishing and equipping a 3-bedroom home requires $25,000 to $40,000 in upfront capital before generating revenue, directly reducing your year-one Cash-on-Cash return.
Using the same $600,000 property: if managed as an STR, gross revenue might reach $75,000 per year. With operating expenses at 52% ($39,000), the NOI equals $36,000, resulting in a 6.00% Cap Rate. However, factoring in $30,000 in initial furnishing costs changes the cash-on-cash calculation significantly.
Side-by-Side Financial Comparison
Let us look at a leveraged scenario for a $600,000 acquisition:
- Purchase Price: $600,000
- Down Payment (25%): $150,000
- Closing & Loan Costs: $15,000
- Debt Structure: 75% LTV, 6.75% interest rate ($2,918/month principal & interest)
LTR Scenario:
- Initial Cash Invested: $165,000
- Annual NOI: $28,272
- Annual Debt Service: $35,016
- Net Annual Cash Flow: -$6,744
STR Scenario:
- Initial Cash Invested: $195,000 (including $30,000 furnishing)
- Annual NOI: $36,000
- Annual Debt Service: $35,016
- Net Annual Cash Flow: $984
As debt costs fluctuate, investors must evaluate whether the incremental NOI of the STR model ($7,728 in this scenario) justifies the operational intensity, furnishing wear-and-tear, and regulatory overhead.
Regulatory and Local Risk Factors
Investors deploying capital in Broward and Palm Beach Counties must perform strict regulatory due diligence before closing:
1. Municipal Ordinances: Cities like Fort Lauderdale and Hollywood mandate short-term rental registration, noise monitoring, and annual inspections. Unincorporated Palm Beach County has distinct registration guidelines. 2. HOA and Condo Restrictions: Many Florida HOAs enforce minimum lease terms (e.g., 30-day, 90-day, or 12-month minimums) or limit the percentage of leased units. 3. Insurance Premiums: Short-term rentals require commercial hospitality endorsements, which can increase property insurance premiums by 15% to 30% compared to standard landlord policies.
Choosing the Right Strategy for Your Capital
If your objective is passive wealth accumulation with predictable debt service coverage, long-term rentals in prime Broward or Palm Beach County submarkets remain the most stable vehicle. If you are seeking yield optimization and have the operational bandwidth or management partner to absorb seasonality, short-term rentals offer higher total return potential.
