The agent that I worked with for my SFR rentals at columbus, OH recently came up with some options on mobilehome/parks investments.

She is working for federal government and had deployed out to another state (she is not a service member by SCRA).

I found it listed by an agent.

I'm a local agent, and I tend to work with investors and investment property, looking to take on more, so i was calling on your property _____ and was wondering , HOWS IT GOING? 

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

Your insurance is going to be highly variable and I wouldn't use what an agent or the seller tells you as the cost of dwelling policies have increased substantially over the past few years due to rising new construction costs. 

I am an investor and full time RE Agent that serves the Gulf Shores / Orange Beach area. 

The agent's compensation is negotiable and 6% may be more common if that includes the buyer's and seller's agent, but if the 6% only covers the selling agent, then that's a greed reach especially considering it's a 2m+ sale price.

Because it's better to hire a professional agent to represent you.

One way to learn is to become an assistant to a Real Estate Agent who works with Investors and House Hackers.
