In an ideal situation the PM is using their network/reputation/experience/cost-efficiency-of-scale to get a better/faster/cheaper repair done for you and are then marking-up the invoiced cost to you, which is usually a fair deal for landlords. 

I also believe I have a reputable CPA as I use The Real Estate CPA group (Brandon Hall) and they have helped draft my entity structure.

Do your research and find a sponsor that has a reputable track record.

Person B might have to send XX,XXX mailers to get a deal because they're very nervous on the phone, don't follow-up on any leads and have a reputation in the community as a bad person. 

@Joe SplitrockI agree with Joe - if you use a reputable PM company I don’t think you increase your risk and can save yourself the time of writing checks each month.

Then you could face reputational risk with some media shaming if some groups get involved.

Hello friends,     I am looking for a reputable and (somewhat) budget friendly modular builder here in Southern California to build an attached ADU (approx 500 ft^2).

Hello BP Community, checking to see if any reputable tax professionals/CPAs that can be referred in the Chicagoland area?

If your inspection going in doesn't catch them, your profit will be gone very quickly, and you will be out money.With 100k cash, I would recommend either trying to partner with a flipper to start getting some deals done, or looking at some turnkey rentals from reputable specialists out of state.  

It's cutthroat everywhere in this business and this industry takes a big hit in both reputation and income because some realtors are willing to work for less than they deserve.
