Nearly half of Charleston's homes sit in two-to-four family buildings. For an investor on Staten Island's South Shore, that single number explains why this small neighborhood deserves a closer look than its size suggests.

Charleston sits in ZIP 10309 on Staten Island's southwest shore, between Rossville and Tottenville, with the Bricktown shopping area on one side and the Arthur Kill industrial corridor on the other. PropertyShark counts 808 residential units in Charleston: 424 single-family homes and 384 units in two-to-four family buildings. That is a 48% share of small multi-family housing, far higher than most South Shore neighborhoods, and it is why investors buying a house with rental income keep ending up in Charleston.
PropertyShark puts the Charleston median sale price at $775,000 for Q1 2026, up 1.3% from $765,000 a year earlier, on seven recorded sales against three in Q1 2025. The median price per square foot rose 8.5% to $412. PropertyShark had not yet posted a Q2 2026 figure for Charleston, and seven sales is a thin sample, so Joseph Ranola underwrites every Charleston purchase off the closest comparable two-family and single-family sales rather than the quarterly median. A current estimate for a specific property starts at the Staten Island home value page.
There is no reliable Charleston-only rent figure, so Joseph Ranola starts from the borough and adjusts. Zumper's Staten Island rent report, updated September 28, 2026, puts the borough-wide median rent at $3,000 a month, with two-bedroom apartments at $2,850 and three-bedroom apartments at $3,400. Those are borough-wide numbers, not Charleston numbers, and a Charleston rental unit is priced against nearby South Shore listings, parking, and the size of the unit. Joseph Ranola runs the rent on each unit separately before an investor commits, because one overestimated unit is usually the whole margin on a two-family deal.
A leveraged Charleston purchase has to work at today's rates, not the rates of two years ago. Freddie Mac's Primary Mortgage Market Survey put the average 30-year fixed rate at 7.03% for the week ending September 24, 2026, up from 6.30% a year earlier. At that rate, owner-occupied two-family purchases, where the buyer lives in one unit and rents the other, usually pencil out better than a pure investment purchase, because owner-occupant financing carries better terms. Joseph Ranola models both versions for Charleston buyers before an offer is written.
Not through the city's basement legalization program. Local Law 126 of 2024 created a pilot to legalize basement and cellar apartments, and it covers selected community districts in the Bronx, Brooklyn, Manhattan and Queens but no Staten Island district at all. An investor who buys a Charleston house counting on a basement unit is counting on an apartment the program does not reach. Joseph Ranola is a real estate broker, not an architect or expediter, so any plan to add a unit belongs with a licensed architect before you sign a contract.
Charleston sits inside the Special South Richmond Development District, a zoning district designed to pace new development with roads, sewers and the protection of natural features. The biggest recent change came in 2013, when the City Planning Commission approved rezoning a 93-acre Charleston site from manufacturing to commercial and residential use (C 130279 ZMR). The approved plan called for about 279,000 square feet of retail, a 15,000 square foot library, 162 senior housing units, a 750-seat school and 43 acres of parkland. Land along Arthur Kill Road remains zoned for manufacturing, which is worth knowing before buying a house that backs onto it.
Investors hire Joseph Ranola because the difference between a good and a bad Charleston two-family is in the details: a legal certificate of occupancy for both units, realistic rents, and a price that still works at a 7% rate. Joseph Ranola lives and works on Staten Island and has represented investors buying and selling across the South Shore. One repeat investor put it this way in a verified Google review:
“I buy & sell properties frequently. Joseph Ranola is great to work with. I have used his firm on a few projects. The team is eager to help & always available.” — Joe Obrien, verified Google review
