How Should I Structure My Business

[Marvin Rice]

I am investing in Michigan.  My questions are as follows:

I have an LLC. Should I purchase properties in my business LLC name or should I purchase each property in it's own LLC name and show my biz LLC as the owner the property LLC?

If I have a partner on a deal, should I use my biz LLC on the partnership agreement or name myself as the partner?

My goal is to build credit for my business to create credit lines and protect my personal assets from lawsuits.
