Castle Shannon, PA: average rent, home values, and rental yield
Middle Atlantic · Population 8,209
Why this market does or does not qualify
Overall City Market Score rank #3,158 of 4,812. The standardized Buy & Hold screen cannot produce a complete result for this city.
Supported strengths
Cash Flow 68/100 and Stability 63/100.
Measured weakness
Growth is the weakest category at 18/100.
Missing screen inputs: investor-entry price estimate. Primary evidenced risk: income growth is the weakest measured factor (4th national percentile).
Data caveat: no missing input is treated as a zero cost. Bring an actual property’s price, rent, taxes, condition, and insurance quote to the calculator.
Why this grade
Overall 41.9 is a weighted geometric mean of the three category scores. Because they are multiplied rather than averaged, their distances from a perfect 100 combine as an exact identity, and each category's share of that distance is the arithmetic below, not an estimate. Growth carries 69% of it, which is what makes it the binding constraint on this grade.
Inside Growth, the shortfall splits over the factors the model scored here, exactly, in proportion to their published weights. The largest component is population growth (weight 12 of the category's 35, 13th national percentile, 36% of the category's own shortfall); next is job growth (weight 12 of the category's 35, 14th national percentile, 36% of the category's own shortfall).
What this is not. It is not a claim that a different value on any one factor would produce a different score or a different grade. Every factor is scored as a national percentile and the grade is a percentile cut against the other 4,812 ranked markets, so this market's position moves only relative to all of them, never on its own. All 13 factors were measured for this market, so no category is carrying a gap.
How Castle Shannon ranks nationally
Each row places Castle Shannon against all 4,812 ranked U.S. markets. The marker is this city; the centre tick is the national median, and the bar spans from that median to the marker, so its length is how far from the middle of the country this market sits and the side it falls on is the direction. Further right is more favorable to an investor: inverted measures (crime, vacancy, price-to-income) are already flipped so higher always means better here.
What a deal looks like here
We can't build a representative buy-box for Castle Shannon yet: no investor-entry price (Zillow Bottom-Tier ZHVI) could be identity-matched to this market. Rather than fabricate numbers, bring your own price and rent to the calculator.

Some seller leverage (31st percentile among 6,196 cities with Redfin coverage)
Equal-weight composite of three Redfin signals’ national percentiles (days on market 37, months of supply 2.1, sale-to-list 101.6%), direction-adjusted so a higher percentile always means more room for a buyer to negotiate. This is a cross-sectional snapshot against every other tracked city today, not a seasonal or historical baseline for this specific city (no multi-year time series is committed for this data). Not a prediction of what any specific seller will accept. Source: Redfin Data Center. See how this is calculated.

ZIP markets in Castle Shannon
2 Census ZIP Codes (ZCTAs) officially overlap Castle Shannon by land area · 2 data-eligible for subscores. Overlap is Census land-area share, not a population or address share. Each ZIP Code's overall Rental Investor ZIP Score, grade and canonical national rank are shown below (the two component signals, affordability and rental market, are separate percentiles). There is no city-scoped ZIP rank: city overlap isn't a ranking universe, so only the national rank is shown. These ZIP rankings sit in the ZIP universe only, never mixed with, and not directly comparable to, Castle Shannon's city ranking. Vintage: the Key metric column below is Census ACS 2020–2024 (5-year), the same survey release as the figures used above for Castle Shannon itself; a city and a ZIP Code are different geographies, so the same measure can still show a different number at each level.

The honest read
Castle Shannon scores 42/100 overall (grade D): 68 for Cash Flow, 18 for Growth, and 63 for Stability, each a 0–100 score built from the factors in that category. The scenario above shows what a representative investor-entry purchase pencils out to at today's rates. Everything we can measure is in the table below, with its source.
Every factor, shown
The Overall score blends three category scores built from thirteen measured factors: Cash Flow (35%), Growth (35%), and Stability (30%). The table shows every factor; the tag on each percentile marks which category a scored factor feeds. Untagged factors are shown for context but not scored. Every percentile also carries the band it falls in - top 10%, top quartile, above or below the national median, bottom quartile, bottom 10% - so a bare ordinal still reads as a position; the band restates that percentile and adds nothing to it. Every value carries its source and as-of date. How the score works.

|---|---|---|---|---|
| Expense-adjusted yield fallback | 3.0% | Above median56th percentile · Cash Flow | Census ACS · ACS 5-yr 2020-2024 | Annual rent divided by price, net of a modeled vacancy, tax, capex, and management allowance: the core of the Cash Flow category and what the score is actually computed from.

| Rental vacancy | 6.2% | Below median35th percentile · Stability | Census ACS B25004 · ACS 5-yr 2020-2024 | Share of rentals empty. Lower means more pricing power. A Stability-category factor. |

- † Job growth and unemployment are county-level (BLS LAUS, county FIPS 42003); large multi-county cities inherit their dominant county’s figures.
- Yield uses ACS median gross rent and home value (Census survey data, 2020–2024 average) because Zillow does not cover this city - not directly comparable to Zillow-based yields.
- Data flag: cashYield: ACS fallback (no Zillow rent+value).
- Data flag: rentGrowth: ACS CAGR fallback.
