To be clear, I should ask for who his builder's insurance provider is?

The agent wont be able to provide you much other than support since its a wholesale deal.If you want to include your agent in on the fun just throw a 1% fee their way and just let them do the rest.

Depends on who is buying.

When it is asking for personal information, do I need to provide my personal first name, last name etc, or can I provide LLCs information?

@Linda BarYes, but It would depend on how your policy is structured.

Please let me know if there are any recommended sources to obtain business lending for start up businesses and provide assistance to maintain healthy business credit. 

Our program is designed to provide both mentorship and practical experience by funding your deals and sharing the risks and rewards.

Any recommendations on companies that provide these services?

I suppose there are counties out there that would allow it but it would depend on how they define the structures you are building. 

Hopefully something can be done depending on city regulations.
