It seems the cons are rather obvious (diverting my focus and attention, having to find another network of professionals I can trust, less economies of scale, more travel) and I'm not sure there are a whole lot of benefits.

Also interested in networking with realtors, wholesalers, RE lawyers etc. in the area. 

I have a CPA who also is an investor, I have a contractor, and a real estate agent.

If you have little money to work with, then use your time... post ads on Craigslist, attend your local REIA and any other Meetup groups, network, door knock, do Driving for Dollars, hand write and stuff your mailers, etc, etc, etcIf you have the money but not the time, then you pay someone to do the above things.If you have neither the time nor the money you won't make it very far...

I use a CPA, he charges separately for my personal taxes and for each entity. 

(until we sell)I assume starting a buisness and putting the 3 homes under the buisness would be the best thing to do.We are really interested in someone who has done this or knows the laws.Thank youJoy Sounds like you might have a need for a CPA?

I am not a CPA, but @Vlad K. is, and hopefully he can chime in to help you out. 

Continue to learn, network, & most importantly work on your personal financial situation.

I was hoping to get in touch with a CPA to work on some tax planning for 2018 as well as get a better handle on 2017.  

I have tried Direct Mail, Driving for Dollars, Door knocking, Property Tax Lien list, craigslist and develop a referral network with an Estate Sales company.
