I would fist run the numbers to see if it is a good deal at the price and everything else, and then I would drive down the streets to see if you see any licensed contractor signs/trucks.

@Jorge Caceres Is this with electric baseboard heaters or  heat pump/minisplits.

My wife and I are real estate investors based in Katy, and I/we are looking to connect with local investors, real estate agents, property managers, and contractors in the area.

Personally, I would never invest in a place I didn't even visit and also meet/interview the people who would be involved (agent, manager, contractor, etc.)

I would say you need to find the contractors first. 

The time has come for me to start investing in real estate and before doing so i'm looking to build a strong and dedicated team of partners: agents, lenders, contractors and property managers mainly in the Cleveland area (but also open to markets within a 2-3 hr drive away) that already possess an excellent track record in their line of work and that value long term collaboration.

Instead of platforms like Angi, try building relationships directly with contractors, architects, and developers.

Last piece of advice is to surround yourself with quality service providers (real estate brokers, lenders, accountants, attorneys, PM's, Contractors, Insurance Brokers)., They will be instrumental to your business. 

Our contractor was a crook.

I would suggest you hire an inspector as well as have a general contractor go out to the property.
