I wanted a place in a A class neighborhood in Chicago with good tenants How did you find this deal and how did you negotiate it?

It is a protected class in several states...

While I don’t know their program or them, I’ve yet to see a mentorship program that cuts the time necessary to obtain the knowledge required; that has a monopoly on any tactic, strategy or technique that’s not common knowledge; and or that provides any ongoing “help” that’s anything but “basic”.If you’re not well versed in principles, finance, and law, either read books on these, attend college classes, or take a course(s) leading to real estate broker (salesman) licensure.  

I assume the effectiveness is written on each one and I also assume they must perform that well or face class action lawsuits.

C class area I wouldn't want to be all in (purchase plus rehab) for anymore than 75% of ARV since I know that's pretty doable in the Pittsburgh area.Deal #4Basically same criteria as above.

Similarly, if you put several Class D tenants in a Class A 4-plex, what do you think will happen to the property?

Another great option is the BRRRR method (Buy, Rehab, Rent, Refinance, Repeat), where you buy a fixer-upper, renovate it, rent it out, and refinance to pull your cash back for the next deal, and this is a good route because most private lenders can go higher LTV than on a rental loan! 

@Stephen Akindona in our experience, the PMCs offering:- No Termination Fees- Tenant Replacement Guarantees- Eviction Guarantees- Flat Fee Management- Etc.only manage Class A & B+ properties, or bite off more than they can chew and their services suffer.

With the down payment you're putting down (assuming it's at best 25%) with current interest rates, you're maybe going to be scraping a couple of backs cash flow on a Class C+ property. 

@Maurice Smith 2nd vote for RL Management.Regarding owner payout timing, it's easier to pay sooner for Class A rentals, because the tenant payments are more consistent.As you go from A to B, to C, etc., tenant payments are LESS consistent, so many PMCs opt to pay owners later.
