–My Analysis of the 2015 Philly General Election and Increasing Third Party Potential (30 pages with charts, maps, and regression analysis)
Philadelphia Property Prices and Ownership
–Office of Property Assessment — notably the Property Information database — and the OPA has an API
-Most recently OPA has started to use opeandataphilly.org to release property data
–Real Estate Tax lookup – by the Philadelphia Revenue Department. Look up your own or other people’s taxes!
–My Philly Housing Price Map – by square foot, using the 2013 assessments
–My Philly Property Age Map
–My Philly Exterior Property Condition Map
–Guide to Researching Landlords (by me)
–Philadelinquency.com – conservative muck-raking blog about Philly real estate – has a very good tool for searching the Office of Property Assessment’s database
–Quarterly Housing Price Reports, by Kevin Gillen. Probably the best analysis of Philadelphia housing market conditions.
–Zillow.com – property history, and some interesting (but not necessarily totally accurate) forecasts like: 19143 Zip Code
–University City District – puts out an annual report on the State of University City
–Zumper – biased data on the cost of renting which is often quoted in the mainstream media. For instance they have $1350 median for a 1 BR in Philadelphia – whereas the Census American Community Survey says the median rent for all households is $850. This is a general problem with rent data – if it based on a survey with a random sample – it is likely biased. Instead you should use the American Community Survey.
-Google “Philadelphia Housing Index” to find the latest quarterly housing price index produced by Kevin Gillen with neighborhood breakdown and historical data. They don’t seem to have a central website for them. 2015 Q2 report
–Philadelphia annual increase in rent from MPF research (not sure how accurate this is – do they use a random sample?) – 3.2% annual growth as of 2015 Q2
–ACS data on Philadelphia (and PA) renters – note: I’m skeptical about the “renter fraction” data which has only 33% of Philly households as renters – when the number of households that own their home (according to the ACS) is around 52% (Eg. what are the other 25% doing?)
-Census Reporter API call for Philadelphia median contract rent:
(2014 – 1 year ACS summary)
The city produces an annual five-year strategic plan that is chock full of information. (Google “five year strategic plan philadelphia” to get the latest version).
