Williams Island Investment Guide: Rental Yields & Market Performance

Last updated: April 2026

Most people think of Williams Island as a lifestyle play, and it is. But there's a real investment case here too, and it's one we think gets overlooked. You've got waterfront property on a finite island that's fully built out (no new towers are ever going up), a range of price points across 13 buildings, and a seasonal rental market driven by snowbirds, Latin American buyers, and European visitors who come back year after year.

Here's how we break it down for investors.

Why It Works as an Investment

Four things make the island interesting from an investment standpoint:

1. Supply is capped. 84 acres, 13 buildings, and that's it. There's no land left to develop. You can't build a 14th tower. That scarcity matters over time.
2. The amenities drive demand. The Club, marina, pools, tennis, this isn't stuff you get in a standalone building. Tenants and buyers pay a premium for it, and it keeps the island desirable even when the broader market softens.
3. Location. Aventura sits right between Miami and Fort Lauderdale, two airports within 30 minutes, Aventura Mall across the bridge, Sunny Isles Beach 2 miles east. It's convenient for basically everything.
4. You can enter at different levels. Mid-$400Ks in the classic towers, up to $5M+ in a Bellini penthouse. That flexibility lets you pick the strategy that matches your goals.

The Rental Market

There are two ways to play rentals here, and they're very different.

Seasonal (November – April)

This is where the money is. Winter season brings snowbirds from the Northeast, families from Latin America, European visitors, people who want 3 to 6 months of warm weather with resort amenities and don't want a hotel. Demand's strong and consistent.

What are we seeing for seasonal rates?

• 1BR/1BA (1,100–1,400 sq ft): $3,000–$5,000/month
• 2BR/2BA (1,500–2,200 sq ft): $5,000–$9,000/month
• 3BR/3BA (2,500–4,000 sq ft): $8,000–$18,000/month
• Bellini / premium units: $12,000–$25,000+/month

A solid 2BR can pull in $25K–$50K over a 5-month season. Then you either use it yourself in the summer or leave it empty. A lot of owners like that flexibility.

Annual Leases

Lower monthly numbers but you're occupied year-round with steady cash flow:

• 1BR/1BA: $2,200–$3,500/month
• 2BR/2BA: $3,500–$6,500/month
• 3BR/3BA: $5,500–$10,000/month

Gross yields on annual rentals run about 3.5%–5.5%. After HOA, taxes, and insurance, you're netting somewhere around 1.5%–3.5%. Honest numbers, not spectacular, but you're also building equity on a waterfront asset that appreciates.

Which Buildings for Which Strategy?

Cash Flow (Lower entry, higher yield)

1000 Island Blvd is usually where we point first-time investors. Lowest entry price ($400K–$700K for a 1–2BR), 320 units so there's always activity, and the rental market's the most liquid on the island. 4000 and 3000 are in a similar price range, good for buying original-condition and either renting as-is or renovating to command higher rents.

Appreciation (Buy and hold)

Bellini is the play here if you have the budget. Only 68 units, private elevator entry, 10-foot ceilings, there's nothing else like it on the island. Limited supply means prices tend to hold and appreciate. 7000 Villa Marina has the premium address and the widest views. 6000 Bella Mare draws the high-end seasonal crowd, Bay, Intracoastal, and ocean views all from one building.

Renovation Play

Buy original, renovate, rent or flip. 1000, 4000, and 2800 are the buildings where original-condition units trade at the steepest discounts to renovated ones. We cover the numbers in detail in our renovation guide.

What About the HOA Fees?

This is the first thing investors ask about. Yes, the monthly maintenance is real, roughly $800–$1,200 for a 1BR, $1,500–$3,500+ for larger units. But here's what people sometimes miss: those fees include 24-hour security, building insurance, water, sewer, cable, internet (in most buildings), pools, fitness center, reserves. If you owned a standalone house, you'd be paying for a lot of that separately.

The HOA number looks big on paper, but the "net of services" cost is lower than people think. Just make sure you're factoring it accurately into your returns.

Long-Term Outlook

Williams Island held up better than most of South Florida during 2008. The diversity of building stock, the established community, the fact that it's not just one tower but an entire island, that gives it resilience that single-building developments don't have. We saw that play out.

Going forward, a few things work in the island's favor: no new supply (ever), buildings are investing in lobby renovations and common-area upgrades, Aventura keeps growing as a city, and construction costs across South Florida keep climbing, which makes existing, well-maintained properties more attractive relative to new builds. Through early 2026, we're seeing continued demand for renovated units in premium buildings, and seasonal rental rates have held steady or ticked up slightly from 2025 levels.

Williams Island vs. Other Aventura Options

Factor	Williams Island	Standalone Aventura Condos	Sunny Isles Condos
Entry Price (2BR)	$600K – $1.5M	$400K – $900K	$700K – $2M+
Seasonal Rental Demand	Very Strong	Moderate	Strong
Amenity Infrastructure	Community-scale	Building-only	Building-only
HOA Fees	Higher (all-inclusive)	Lower	Higher
Appreciation Potential	Strong (scarcity)	Moderate	Variable
Rental Restrictions	Building-specific	Varies	Often strict

The short version: Williams Island gives you something the standalones don't, community-level infrastructure and scarcity that sustains demand even when the broader market gets wobbly.
