Is there a minimum revenue (if any) is supposed to be generated?

For instance I see "net income" and I don't know if that what the tenant paid or that's what I'm receiving after the property management fee.Net income is revenue minus expenses.

Seems you are new to this- you can get just as good protection by working with an agent or broker and will see more deals through developing that relationship. 

Yes, the BRRRR (Buy, Rehab, Rent, Refinance, Repeat) strategy is still alive in Philadelphia, though some aspects have become more challenging in recent years due to shifts in market dynamics.If you’re considering BRRRR in Philadelphia, areas with recent or upcoming developments, like parts of West Philadelphia, Brewerytown, and sections of Northeast Philadelphia, can still present good opportunities, but base everything on section 8 rents to see if the DSCR and LTV makes sense

Likely, a slightly larger buyer pool.Cons:Less revenue each month.  

If he's a big-shot developer raising millions from investors, he must have assets somewhere.This seems like a scene right out of the movie, "Pacific Heights."

  $50/sqft for a full interior and functional update, $100/sqft for a full gut down to studs, $150/sqft for newcon .If these numbers make sense I would want to visit the property for a true estimate, where it would be line item work scope development. 

The rules are totally pro-scarcity and anti development, that's an excellent business venture if I am pouring in billions. 

It got me thinking about how major developments like this are impacting property values, demand, and investment opportunities around our area.

There's a lot of new developments in many areas to consider.If you're considering areas that are a bit further out from Downtown or Midtown such as Marietta, Brookhaven, Sandy Springs, Doraville, Decatur, Duluth, you may be able to find reasonably priced homes.
