In the 2022–2023 IRS migration release, the measured New York-to-Miami corridor contained 17,217 tax-return households and 27,268 exemptions, the IRS people proxy. This establishes a substantial directional flow in the filing data, not a count of lease shoppers. IRS flow means tax-return households; it does not identify renters, every mover, or future demand. Use it as evidence that this corridor existed while keeping housing tenure, move timing, and the destination submarket unknown.
For household housing costs, the June 2026 market snapshots point to a lower headline entry price in Miami. Zillow asking rent was $3,573 in New York and $2,695 in Miami, a destination difference of negative $878 per month and negative $10,536 annually. Zillow home value was $735,003 in New York versus $476,598 in Miami. Separately, the 2024 BEA housing price-parity index was 155.551 in Miami and 148.616 in New York. The move therefore lowers the rent and home-value benchmarks, but Miami does not show a lower broad housing price level on that earlier index.
For rental-property underwriting, Miami’s gross-yield screen is higher at 6.78%, compared with 5.83% in New York. That is a starting spread, not a return estimate: it excludes operating expenses, financing, vacancy, concessions, taxes, insurance, association charges, and repairs. The FEMA annual building-loss ratio also rises from 0.1085% in New York to 0.1935% in Miami, changing the insurance and physical-risk diligence. The next underwriting question is: what are the property-specific recurring costs and achievable net rent after insurance, taxes, association obligations, vacancy, and unit-level condition are verified?
