Doing a quick google search, I am not finding any groups here.

People call me all the time asking about such companies.

You have $1.5+ million home and you're paying $2000 property tax a year, probably a paid off mortgage  if you bought in 1970 for example, and can charge market rate rent (multi units are under rent control with existing tenants, generally speaking, but not SFHs so far) Be really careful with whoever gives you numbers on a spreadsheet whether it's a turnkey company, agent etc. 

I know there are some negative reviews of his company from a couple years ago.

I am looking to buy my first rental property in Louisiana and I want to know which homeowners insurance companies do you recommend me.

From there, I'd recommend reaching out to some of the smaller property management companies in your area.

I'm working for a family run real estate investment company and we're new to the DFW area.

It is managed by a company.

By no means does any modular company use 20% more lumber than a site built home.
