What really matters is what's important to you and whether or not your agent has the skill and market access to ensure you're getting a good value.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Anything related to Work Comp is VERY state specific and as an insurance agent who is also a fix and flipper I'll say this - unless you outsource 100% of your rehab to a GC and your contracts specifically state how the GC is responsible for work comp matters you may not need it.

My agent How did you finance this deal?

Love it. sounds like your client had a good agent ;)Goes to show if you put in the work to find the deals, the right ones will still come you way

Real Estate Agent?

A great investor focused agent, coupled with a great PM, can get returns in a bad market if they know what they are doing.Investors should pick market based on barrier to entry and their available Capital and their strategy. 

The local agents & management are great resources. 

A good real estate agent that works in your market should be able to help identify desirable neighborhoods, as well as realistic prices.

When you transfer the properties to LLCs, speak to your insurance company/agent to have them make sure that the LLC's name is on the policy.
