@Nathan Becker one thing to consider specifically in TN is the F and E tax as it relates to LLCs.

He said we’d have to do schedule k rather than schedule e.

They seem brand new.

I assume you filed a schedule E.

He said the brand of deadbolts were junk and saw this all the time.

For a brand new agent, it’s valuable education getting training, learning all the necessary tools to legally represent a client the sale or purchase of their home or commercial building. 

I can forsee selling real estate you don't own starting to get on the radar there is just too many people being talked into it and doing it.. and then posting on Craigslist.. and I have never seen a add for a contract.. every single e mail I get or add I see is just what an agent would do. picture of house sq ft bd ba etyc etc..

But my sample size is greater here in the US. ya myself I had horrid room in Venice  also Rome   London and Paris were OK when I went for local brands.. 

I found a builder's ad from May 1960 offering a brand new ranch home for $21,000.

Yes, you can use a regular email address for your business LLC, but having a professional email address associated with your domain is generally recommended for a more credible and branded image.
