I work for a building materials company now and took their online game from Zero to very engaged in the past few years and it's been really fun.

I do SMS, cold call, mail, online, wholesalers, etc.

Online platforms like Zillow, PropStream, and Auction.com are worth exploring, and don’t forget to check out local real estate groups for deals and partnerships.Since you’re in Racine, the Rental Property Association of Wisconsin and Milwaukee REIA are great resources for networking, finding contractors, and learning about funding opportunities.

Yeah they have a good reputation so far and Vincent is solid.

Call a different number you found online associated with the same company, etc. 

If I am self managing my portfolio, what do I need to check/confirm, and what easily available tools are at my disposal (online, other) to help me do this? 

You can also check their reviews online at Google, Facebook, or Yelp.

I would never form an entity with them when I can do it online with a firm that charges a fraction of what they charge).

I am still living in the past, where your word is your reputation and your reputation is your character. 

.: As a contractor and flipper, I dont buy materials from retailers or online.
