As you'd expect these giys are super busy an d you can't get a quote frpm them to save your life unless you said the magic words;  "I'm desparate and will pay 2x the actual costs today for you to take this job".   

Also what could I be getting myself into that I’m not thinking of or simply bypassing here..Who is expected to pay for this ordeal in this type of situation..and for what exactly?

She better make a lot of money or marry someone rich because she has some unrealistic expectations. 

think about how long it will take to recoup all the costs i just mentioned.if you want day 1 cash flow... open a savings account.i say this not to discourage you but to help set expectations.

I have been looking into the South Philadelphia market as the area is expecting the Bellwether District, a megadevelopment of industrial and life-science buildings, to be delivered in phases over the next dacade.

During the inspection period, you should send someone to take good pictures of the house to confirm the condition you were expecting based on how the seller described it over the phone.

You should not expect things to go smoothly.

Vetting tenants is essentially the same as regular tenants, but expect lower credit scrores, bankruptcies, etc.  

Purchase price maybe $120,000  a door, that seems high to me for 70s product, but I just don´t remember prices at that time.   

--------------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a Class A property in Class D area, what quality of tenant will you get?
