Are there any locals that can point me to recent data such as days on market, list v. sold price,  average price, percent of price reductions, etc. or even first-hand observations?

They have a free option called data.rabbu.com, but I also use the paid service that they provide additional market data.

Zillow/Redfin data shows a price decrease of 13.5% from the highs of May/June. 

Median is 155k, B and C are above and below median, here is what you get:and from what I can see in the data, here is the hood. 

These numbers do not include any FSBO or other "off-market" sales which do not appear on the MLS.The data includes all Single Family, Condos, and Multi-Family from 2000 to the present.

Small rural America towns the few data points can be distorting.

Seems to be a healthy local economy with 3% unemployment to boot from looking at census data.

Here are some links that I have that helped me with my research: http://www.revenue.pa.gov/GeneralTaxInformation/TaxLawPoliciesBulletinsNotices/TaxBulletins/RTT/Documents/rtt_bulletin_2008-01.pdf https://www.foxrothschild.com/publications/update-realty-transfer-tax-on-assignments-of-agreements-of-sale/ https://www.ballardspahr.com/alertspublications/legalalerts/2008-04-29_pennsylvaniarealtytransfertax.aspx https://www.pabulletin.com/secure/data/vol37/37-50/2306a.html

Skip the score and look at the individual data - types of accounts, number of lates, balances, etc.

Even then if you compare it with another normal house, the profit margin in the latter would bigger than the condos.I think condos are best only when they do not need any repairs.I don't think there is any actual data to back up your claims that condos are not great investments (relative to SFH).
