Miami Investment Property Analysis: How to Run the Numbers in 10 Minutes (2026)
The 5 Numbers That Make or Break a Miami Deal
Most investors who lose money in Miami real estate didn't fail because the market was bad. They failed because they skipped the math. Here are the five metrics that determine whether a property is an investment or an expense:
Know Your All-In Monthly Expenses
This is where most rookie investors blow the analysis. They calculate mortgage + taxes and call it a day. Here's the full picture for a Miami investment property:
Miami-specific warning: FL insurance averages $2,500–$4,000/year for a $380K property. Coastal zones can be double. Always call three agents for quotes — don't use Zillow's estimate. Miami-Dade property taxes reset to non-homestead rate at purchase; never use the seller's tax bill if they had homestead exemption.

Cash Flow Examples: F-Grade vs A-Grade Miami Deal
Back to the Hialeah example. A 3bd/2ba at $380,000 renting at the median ($2,250/month):
Same Hialeah neighborhood, very different outcome. An A-grade deal looks like: the same duplex but distressed — priced at $340,000. Same rents, cash flow jumps to $580+/month, cap rate hits 6.1%. That is the deal SpillDeals surfaces and grades A automatically.

Miami Markets That Actually Cash Flow in 2026
Not all of Miami-Dade produces investable returns. Here's the honest breakdown:
Hialeah — High density of duplexes, strongest price-to-rent ratio in the county. Homestead — Lower prices, growing fast, FHA house hacks work well. Opa-locka — Highest cap rates in Miami-Dade; higher risk tolerance required. West Little Havana — Emerging, still affordable small multifamily.
Brickell / Edgewater / Wynwood — Terrible price-to-rent ratios. Buy for appreciation only. Miami Beach / Coconut Grove — Beautiful, expensive, doesn't pencil for rental income. Coral Gables — High-quality rentals, but prices make positive cash flow nearly impossible.
Every morning, SpillDeals analyzes every active FL listing and grades each one A through F using this exact math — real insurance estimates, non-homestead tax rates, and HUD Fair Market Rents. Filter for A/B in Miami and you'll see the 8% that actually cash flow, without building a single spreadsheet.
