As far as the Tech Stack goes, a common mistake is not considering what future tech you want to use, then you're stuck with things that don't integrate (API out) to it, and you get really limited in future options. 

If you get a higher income tenant (e.g engineer, tech worker, doctor, RN, etc) you may be able mitigate some risk.

Texas offers a diverse real estate market, from the tech-heavy Austin area to the sprawling suburbs of Dallas and the oil-rich Houston market.

But they use high level tech....pre screen, self showings, and the 1225 is the standard fee for first month lease up services including them drafting and getting tenant to sign lease..

Id say 3 weeks is an unacceptable timeline for a landlord to leave a giant hole in the wall.

Yes Philly is a city of neighborhoods and one block can make a giant difference as well a lot of streets there were low value are being redone and very desirable 

The population is growing, there's tons of development opportunities, and a nice mix of industries - tech, healthcare, manufacturing, etc.

I have a nice hi-rise condo unit and I get tons of companies asking if I do MTRs for Visiting Nurses, Tech Professionals, etc.My place is positioned near a number of large DC Metro Hospitals, but since covid work-from-home and recent lift of Eviction Moritorium, I have had few people with jobs, but a ton of people recently evicted looking to rent my place.The one viable group - visiting nurses has been excluded because my HOA will not allow short or mid-term rentals (anything less than one year is a No-No).They claim too many transient tenants cause excessive wear and tear on the property and too many people using resources like the gym, or pool or common areas.I think that's a lot of horse waste!

And that is true, but that is also sort of like saying "to mitigate the risk of investing in Apple, and relying on their decisions, I will start my own tech company" (okay, that is a bit extreme, but you get the idea).  

I no longer get tech support/updates, but the software does what I need it to do pretty reliably.
