Small multifamily investing in South Florida. Do the numbers still work in 2026?

Introduction

Small multifamily properties continue to be one of the most popular investment options in South Florida because they offer multiple income streams while remaining easier to finance than larger apartment buildings.

A duplex, triplex, or fourplex can generate consistent rental income, help offset financing costs, and build long-term equity. However, a property that looks profitable online isn't always a good investment once you factor in insurance, taxes, maintenance, vacancies, and financing.

Before making an offer, every investor should evaluate the numbers objectively—not emotionally.

The most successful investors focus on cash flow first and appreciation second. Buying the right property at the right price is what creates long-term wealth.

What should you analyze before buying?

Before purchasing a duplex, triplex, or fourplex, review these key factors:

• Purchase price compared to recent comparable sales.
• Current rental income and market rental rates.
• Vacancy history in the neighborhood.
• Property taxes and insurance costs.
• HOA fees (if applicable).
• Maintenance and repair expenses.
• Roof, plumbing, electrical, and HVAC condition.
• Financing costs and interest rate.
• Property management expenses.
• Long-term appreciation potential.

Never rely only on the seller's projections. Verify every number before moving forward.

Case Studies

Case Study 1: The Triplex in Fort Lauderdale

A client approached me about a triplex listed at $750,000. The rent roll suggested total monthly income of $4,500. However, after evaluating the vacancy rate of 10%, insurance costs at $1,800 per year, and property management fees of 8%, the net cash flow dropped significantly. We had to negotiate the price down to $700,000 to make the investment worthwhile.

Case Study 2: The Duplex in Miami Beach

This property was marketed with a strong cap rate of 6%. Upon inspection, I found substantial repairs were needed, which would cost nearly $30,000. The expected rent growth was optimistic given current market conditions. This case highlighted how superficial online listings could mislead investors into thinking they were getting a good deal.

Case Study 3: Fourplex in West Palm Beach

A fourplex was listed at $1 million with a promising cash-on-cash return of 9%. After conducting a thorough analysis that included reserve funds for unexpected repairs and tenant quality checks, we discovered one unit had chronic maintenance issues. This discovery led us to walk away from what seemed like a great opportunity.

FAQs

What should I consider when evaluating a multifamily property?

You should assess purchase price, potential rents, vacancy rates, insurance costs, taxes, and necessary repairs. Understanding these metrics will give you a clearer picture of your potential return on investment.

How do I calculate cap rate?

Cap rate is calculated by dividing the net operating income (NOI) by the property's purchase price. A higher cap rate usually indicates a better return but may come with higher risks.

What are common mistakes investors make?

Many investors overlook hidden costs like maintenance and management fees or fail to account for market fluctuations affecting rent prices.

Is it better to manage properties myself or hire a management company?

This depends on your experience and available time. Managing yourself can save money but often requires significant time and effort.

How do I know if a property will have strong rent growth?

Research local market trends and economic indicators. Areas with growing job opportunities and infrastructure improvements typically see better rent growth.
