I'm not all that familiar with NYC markets, however in regards to investor interest, the miami sub-markets are pretty straightforward. Condo/rental markets are concentrated on the waterfront strips in the city (coconut grove, brickell, bayfront downtown, edgewater, etc.), and then further up miami beach into sunny isles/bal harbour. There's a few popular buildings in south beach and south of fifth but they're not huge markets. For single family homes you have established markets in coral gables, pinecrest, south miami, and miami beach. Then up and coming markets in wywood, midtown, and mimo districts. All markets saw a build up of inventory across 2017-18 causing a pretty relentless buyers market. Over the past couple of years we've seen that nearly clear, and with the current global uncertainty I wouldn't be surprised if investors who had interest in branching out to smaller, more up and coming markets, start to fall back on the larger staple gateway markets of NYC, Miami, LA. When it comes to pricing structure; the rent per square foot, price per square foot, and property appreciation are relatively uniform across the individual submarkets so if you wanted to calculate or even model out potential rental yield it shouldn't be a large hassle.
