The MiamiLi Read

The lines below are derived automatically from this listing’s own data and the area’s recorded deed transfers. They are not a personal opinion or investment advice.

  • Price per square footThe asking price per ft² on this listing is $1,886. The median for recorded sales in the same ZIP codes is $606/ft² — putting it 211% above the median.
  • Position in the area’s price distributionThe asking price is $3,300,000; the median of recorded sales in the area is $590,000 (2,281 sales). On raw price that is 459% above the median — this line does NOT adjust for property type or size.
  • HOA fee as a share of priceAn HOA fee of $1,960 per month comes to $23,520 a year — 0.7% of the asking price. That amount is deducted from rental yield.

How to read this comparison: the figure on the left is an asking price, while the one on the right is a closed sale median — the two are not the same thing, and the room to negotiate sits inside that gap. The median covers every property type and size in those ZIP codes; it carries no adjustment for a single listing’s floor, view, age or finishes. This box is not an appraisal.

Scope: ZIP codes 33139, 33140, 33141 · arm’s-length sales recorded by the Miami-Dade County Property Appraiser.
