Welcome, best of luck on your journey. this is a great platform to be in

Quote from @Isaac Watson: @Charles Perkins are these meetups on platforms like meetup.com?

Is that something you're offering on other platforms as well? 

I am seeking recommendations for an app that can integrate with multiple platforms.

If you’re in Texas, platforms like Propelio and the CAD websites are particularly effective.

I've been a member of BiggerPockets for 5 years or so, but have never truly contributed to the platform.

To find deals in Philadelphia, focus on off-market opportunities by networking with wholesalers and local investors, attending meetups, and leveraging platforms like PropStream or MLS.

That means, a very good for holders deal is published, with potential future benefits from the platform for those who accept.

Are there any key resources, platforms, or strategies you’d recommend for a beginner? 

Pick a screening platform/application that makes sense for you.As for meeting the applicants, I recommend meeting them at the property to show the place to them rather than getting coffee or food with them.
