I am very data driven and I simply don't see Philly as an attractive destination unless you are -- local, hands on, DIY, don't have prop mgmt expenses, don't pay leasing commissions, get preferred rates from lenders, know a guy who does handyman work, etc. 

That can lead to odd quirks, sometimes good deals, and sometimes long and arduous processes, it just all depends.I will share a story - one Credit Union was offering such attractive HELOC terms that Auto Dealerships caught on to it.

The reality of the matter is, the location will attract the appropriate tenant profiles.

I'd also consider what the local attractions are, and if that area is growing.

I understand this however the attractive of real estate vs other investments is that with real estate you are making money (appreciation) out of some one else’s money and not only your investment right ?

As a result, the property became more desirable and attracted more high-quality traveling medical professionals.

@Dave Skow Exactly, the 95% LTV is what attracted me initially.

If you buy a package of 6 lesser houses  that means I have 6 roofs, 6 hvac, less cashflow, and likely subpar appreciation(dollar for dollar) compared to better areas.The reduced maintenance costs, higher rents, better tenants, appreciation, and reduced hassle factor for new construction are real and attractive.  

Areas with good school districts, public transportation, and amenities tend to attract reliable tenants. 

I also did look into Salton Sea for STR, it didn't look very attractive for STR.
