What specifically are you looking for in terms of investing? 

NYC apartments will have a different car requirement from Orlando, but he used that methodology in this specific small city and was an investor from the 1980s-2000s, so a lot has changed, but I believe there is still some truth to it.

If I ever have specific questions, I look through google and then use the BP forums as another source.

I have all kinds of specific searches set up for my investor clients to help find the best deals. 

Are there specific market indicators or property traits I should be paying attention to?

Paid platforms often offer additional features like market analytics, off-market property leads, and filters for investor-specific criteria, giving them a leg up over free options.Exactly, most platforms have to offset cost somewhere because of how expensive it is to keep the data up to date.

To maximize returns, ensure compliance with local regulations, prioritize owning the land, and offer student-friendly amenities.

@Eric Andersen definitely put weight into what @Michael Baum wrote and do your own research on the city regulation/zoning.

One of the most important steps you can take as either a startup landlord or seasoned one is to use a platform specific to property management as it will elevate your operation and save you tons of time.The good news is that nearly every software designed for landlords includes these features.

It's a winning combination of direct access to industry experts coupled with building lasting relationships and get direct feedback on your strategies in small-group format.
