Did you encounter any opposition or criticism of their services from an attorney or accountant?

@Jordan BowenProperty Management is critical, you won't get anywhere without decent management.I would add a larger buffer in your analysis.

Any advice or Constructive Criticism will be taken into account and thank you all so much in advance!

Doesn't sound like you have a motivated seller on your hands which is critical to getting a good deal.

For example, HVAC filter cleaning/swaps could be a candidate for placing all on the same schedule (but we use handyman for these type of activities and it requires less of our effort than the backflow valve check and therefore is not as critical).Auto pilot.

Location, location, location is critical in St.

@Alex Stoll Good property management is critical but what's even more important is knowing the right areas and buying only in good neighborhoods.

Based on the info you provided it’s hard to make any assessment on that critical element.

Is someone buying up properties, looking like they are trying to get a critical mass to build apartments or something? 

I'm still a few months from pulling the trigger on an actual deal, so I would love to hear constructive criticism now!
