im starting my journey in real estate investing, i travel alot for work through multiple states, i enjoy looking over deals and seeing what added values i can bring to any property, depending on what state im working in, im usually there for months at a time, this gives me alot of time to look areas over and process deals, looking over property management companies for that area, im looking to invest in residential homes and commercial multi family homes.

You get a title report from a title company.

I am an investor in Central CT and also own and operate a Property Management Company. 

However, I was eager to pursue my vision of what a real estate company should look like.

If you're only planning to represent a few deals per year, you probably won't reach a company's cap and want to look for brokerages that have low commission splits from the beginning.Make sure to figure in monthly desk/brokerage/E&O fees when shopping around.

CPA, attorney, company that provide such service?   

Very efficient.Chances are the older system has substantial duct loss and should be tested.Mini splits have their place but cold air is heavier and drops so the bottom floor doesn't make sense.Electric motors do not raise in load consumption as they age, it's the mechanical work done that raises load, typically deferred maintenance on belts, shives and pulleys.I'd disqualify HVAC companies by asking; Are you proficient in the new Manual J,S & D standards (that will be required in the industry moving forward)These companies will understand laminar flow, stratification and static airflow imbalances that have a great effect on efficiency, operation and longevity of a conditioning system.Get 3 estimates, compare scope & make sure its permitted.

Point being if you Arlet say part owner of a company it wouldn’t it be better to pay yourself than a contractor.

Or pull a list of these companies?

I think a big thing to consider is what socioeconomic tenant base you can deal with, and if you can self-manage or need a management company.
