Common questions

What living in James Island costs, and what the data does and does not explain.

Four questions readers ask most, answered from the committed sources below. Every figure keeps its source, vintage, and limitation; none of it is personal financial advice.

Cost outside housing

How do non-housing costs here compare with the nation?

Day-to-day non-housing costs here run about 5% below the U.S. baseline.

Non-housing index95100 = U.S. baseline
Goods9620% weight
Services9820% weight
Utilities8810% weight

The index weights goods 96 (20%), services 98 (20%), and utilities 88 (10%) over the non-housing half of the model, where utilities show the widest gap below the national baseline at 88. It excludes rent and home prices, so it is not the overall Regional Price Parity and not the overall cost index. Source: BEA 2024 national nonmetropolitan proxy (one shared value set for every unmatched place in this snapshot, so it is not state- or city-specific).

Housing vs state and nation

Is housing here above or below the state and the country?

Typical home value$508,600Census ACS
Typical rent$1,884/moHUD FMR

The typical home value is $508,600 (Census ACS 2024 place estimate). It is 81% above the $281,088 median across South Carolina cities in this dataset, and 68% above the committed $303,400 U.S. baseline used site-wide (Census ACS 2019–2023).

The typical monthly rent is $1,884 (HUD FY2027 2-bedroom FMR, Charleston County FMR area (40th-percentile recent-mover gross rent)). It is 25% above the $1,506 median across South Carolina cities in this dataset, and 40% above the committed $1,348 U.S. baseline used site-wide (Census ACS 2019–2023).

The South Carolina median is a cross-city statistic over the 101 committed city home values and 102 committed city rents (Zillow Aug 2026, HUD FY2027, or Census ACS 2024 as matched per place). It is not a statewide household median and it is not appraised market data. U.S. baselines are Census ACS 2019–2023 5-Year national medians used across this site ($303,400 home value; $1,348 monthly gross rent), and have not been refreshed to the ACS 2024 city vintage or the Zillow Aug 2026 vintage. Any city-to-national gap therefore mixes vintages.

Why the numbers look like this

Which local signals explain the difference?

The committed figures line up: price-to-income ratio and vacancy rate point the same way relative to their baselines (higher ratios and lower vacancy count as one direction, and their opposites as the other), and no compared figure points the other way. That is a description of this one snapshot, not a forecast.

  • Rent-to-income ratioNear baseline

    22% · Typical rent equals about 22% of local median household income (HUD FY2027 2-bedroom FMR Charleston County FMR area rent × 12 ÷ Census ACS 2024 median household income). These are two place-level aggregates, not a measured household or renter burden. The Census ACS 2019–2023 5-Year national medians imply 21%.

    Baseline: 21% implied by Census ACS 2019–2023 5-Year national medians
  • Price-to-income ratioAbove baseline

    4.9x · The typical home value is 4.9 times local median household income (Census ACS 2024 place estimate home value ÷ Census ACS 2024 median household income). This is a place-level ratio, not an individual affordability test. The Census ACS 2019–2023 5-Year national medians imply 3.9x.

    Baseline: 3.9x implied by Census ACS 2019–2023 5-Year national medians
  • Vacancy rateBelow baseline

    6.1% · 6.1% of all housing units here are reported vacant in Census ACS 2024. That counts every vacant unit, including seasonal, occasional-use, and other vacant homes, and it is not current for-sale or for-rent inventory. The population-weighted mean across the committed city dataset is about 8%.

    Baseline: about 8% committed city-sample mean
  • Owner shareAbove baseline

    87.5% · 87.5% of occupied units are owner-occupied in Census ACS 2024, against a committed national owner-occupied share of 64.6% (Census ACS 2019–2023 5-Year national medians). This describes tenure mix — more owners usually means a smaller rental stock, not by itself higher or lower pressure.

    Baseline: 64.6% committed national owner-occupied share

These are associations inside one committed snapshot, not causal evidence. The dataset has no current listings, pending sales, sale timelines, or construction, migration, income-growth, and unit-mix fields, so nothing here proves or disproves a housing shortage: a low vacancy rate or a high rent-to-income ratio can have several explanations. Treat the figures as context for your own search, not as a cause.

Monthly budget by household size

What might a family of five spend per month here?

Estimated monthly cost for a household of five in James Island: $6,934, of which $1,884 is the exact typical rent and $5,050 is modeled non-housing spending. Everyday non-housing costs here are 5% below the U.S. baseline.

For five people the estimate is housing $1,884 + non-housing $5,050 = $6,934 per month, or about $1,387 per person before taxes and debt.

Estimated monthly cost, before income tax, debt payments, and savings
Household sizeHousing (typical rent)Non-housingEstimated totalPer person
1 person$1,884$1,637$3,521$3,521
2 people$1,884$2,659$4,543$2,272
3 people$1,884$3,532$5,416$1,805
4 people$1,884$4,320$6,204$1,551
5 people (example)$1,884$5,050$6,934$1,387
6 people$1,884$5,738$7,622$1,270

Formula: Monthly estimate = housing base + ($3,272 × (household size ÷ 2.5)^0.7 × (non-housing index ÷ 100)). The housing base is this city's exact typical monthly rent; $3,272 is the Census ACS 2019–2023 5-Year national medians median household income ÷ 12 × the model's 50% non-housing basket share.

Inputs: housing base $1,884 (HUD FY2027 2-bedroom FMR, Charleston County FMR area); non-housing index 95 (BEA goods/services/utilities); national median household income $78,538 (Census ACS 2019–2023 5-Year national medians).

Assumptions and limitations behind this table

Model assumptions

  • The Census ACS 2019–2023 5-Year national medians median household income is treated as a 2.5-person reference household whose non-housing share of the basket is 50% (goods 20% + services 20% + utilities 10%).
  • Household size is scaled with an economy-of-scale exponent of 0.7. That exponent is a modeling assumption, not a measured equivalence scale.
  • Housing is held at the same exact typical rent for every household size. Larger households often rent larger units, which this estimate does not model.
  • The non-housing index is applied as a price level only; it does not change how much a household consumes.

Limitations

  • This is a modeled planning estimate, not a measured household budget, a quote, or personal financial advice.
  • It excludes income tax, sales tax, property tax, debt payments (including student loans and car payments), retirement saving, and one-time moving costs.
  • Zillow, HUD FMR (a 2-bedroom program benchmark for the 40th-percentile recent-mover gross rent, not a market median), and Census values are place- or area-level estimates with sampling error and top-coding, not exact local prices.
  • BEA price parities are metro-area values, or one national nonmetropolitan proxy shared by every unmatched place — never city- or state-specific.
  • The income baseline is one committed national value (Census ACS 2019–2023 5-Year national medians) and does not vary by city or by household composition (adults versus children).

Housing and rent: Census ACS 2024 place estimate home value; HUD FY2027 2-bedroom FMR, Charleston County FMR area rent. Top-coded ACS values stay thresholds, never exact medians. Non-housing: BEA 2024 goods, services, and utilities price parities (national nonmetropolitan proxy). Why: rent HUD FY2027 2-bedroom FMR, Charleston County FMR area, home value Census ACS 2024 place estimate, plus Census ACS 2024 income, vacancy, and owner-occupancy fields. National baselines: Census ACS 2019–2023 5-Year national medians (not refreshed to ACS 2024 or Zillow Aug 2026), so city-to-national gaps mix vintages. Budget: modeled from the committed national median household income and this city's exact rent and BEA non-housing index; assumptions and exclusions are listed with the table. Budget is not produced when rent is top-coded.
