Dave's more for a bit of a basic foundation and Tony's more comprehensive.

As a inexperienced investor your comprehension of the numbers, and in particular the value of cash, is as you state challenged.

I have an office that could accommodate 25+ people easily.

I have been looking into Jamil Damjis course, Pace Morby's Course and Lauren Hardy's course for virtual wholesaling and flipping.I am attracted to Pace Morby's course because it is not simply wholesaling but also airbnbs and flipping and pretty comprehensive.

- Keycheck.com comes with Furnished Finder and is pretty solid- TurboTenant.com also has screenings built into their management softwareOverall, I like both as each provides a comprehensive credit/criminal/eviction report.

My first thought is to look in Delaware county, it's right outside West Philly and can easily accommodate a more cosmetic rehab with good tenants around that price point.

You can look at an FHA small multi loan which would accommodate you living in one unit and renting the other out. 

The tenant started out nice, I made a few accommodations when the tenant moved in such as allowing move in 2 days early and not charging rent.

They aren't comprehensive enough to do the full, custom analysis you will really need to break down everything.

If the seller was more accommodating, or their in-place financials were more in line with market, I'd have been out-bid.
