I would be more worried about the fundamentals. 

But the market has strong fundamentals...slowly growing population, and a strong base of jobs, particularly in distribution and government.That being said, the Harrisburg and Lancaster area, like most areas of the country, is quite competitive.

This web site is full of all the information you will need to learn.

It sounds like you feel pretty strong a out your fundamental numbers.

I'm focused west of the city but still feel like the fundamentals for cashflow are there and also for long term strength in the regional economy.Were you in a bidding war, did you feel like you had to overbid the asking price to secure the property?  

What gives me confidence though is a focus on the fundamentals (purchase below market, force equity through rehab, 1% rule for revenue, 50% rule for expenses, conservative financial modeling, borrowing responsibly without over leveraging) that I have learned though books, podcasts and here on the forums.

The fundamentals are good, but if the affordability is not there it will be tough to continue raising rents and creating value.

This is the fundamental problem I have with Wall Street who takes too much fees off the hard working efforts of the middle class.

@Chris CapersI highly suggest you take a step back from trying to entirely self-educate on the web. 

I don't know the fundamentals of the city, property tax rates, etc. but at least with family there someone can tell you "you don't want to go west of _____ St. after 10:00 p.m."
