Buying a Miami Condo as an Investment

Miami draws investors for good reasons — no state income tax, strong rental demand, and a deep pool of short-term-rental-friendly buildings. But the rules and carrying costs make diligence essential. Here's how to evaluate a condo as an investment.

First: what rentals does the building actually allow?

This is the make-or-break question, and it varies wildly:

• Short-term / Airbnb-ready — purpose-built condo-hotels and STR buildings (Natiivo, District 225, The Crosby, E11EVEN, NoMad Wynwood, and others) permit daily/nightly stays, often with in-house management. See our Airbnb-friendly condos page.
• *Short-term lease (not Airbnb) — many buildings allow a 30-day minimum* lease, sometimes capped at a number of leases per year. That's different from nightly Airbnb income.
• Restricted — some buildings require a 12-month minimum or bar rentals for the first year of ownership.

Never assume — confirm the exact rental rules in the condo docs.

The cash-flow math

Underwrite the total cost, not just the mortgage:

• Income: realistic nightly/monthly rent minus vacancy and (for STR) management fees of ~20–30%.
• Carrying cost: mortgage + HOA dues + property tax (you'll likely be under the 10% non-homestead cap, not homestead — see taxes) + insurance.
• Cap rate = net operating income ÷ price. Compare buildings, and be skeptical of pro-formas that ignore HOA increases and assessments.

Financing an investment condo is harder

STR/condo-hotel buildings are usually non-warrantable, so expect a portfolio loan with 20–35%+ down and higher rates — or cash. Read warrantable vs non-warrantable.

The risks that wreck returns

• Special assessments from the milestone/SIRS laws — can erase a year of cash flow. Diligence per the safety-law guide.
• Rising HOA dues and insurance — model increases, don't assume today's number.
• Rule changes — buildings and municipalities can tighten short-term-rental rules; verify current condo docs and local ordinances.

Diligence checklist

• Exact rental rules (minimum term, per-year caps, Airbnb allowed?)
• Building financials: reserves funded, any pending assessment
• Realistic rent comps and occupancy for that building
• Financing lined up for a non-warrantable project

The bottom line

A Miami investment condo lives or dies on rental rules, carrying cost, and assessment risk. Start with our Airbnb-friendly and rental-income filters, then underwrite the total cost conservatively.
