getting property into a llc

My question is:

If I transfer my personal property into/ or out of a LLC, will the transfer be taken as a “sale”, and involve tax consequence?

In some states, it is subject to a transfer tax and reassessment of tax value. If the transfer is not for value, then it is subject to fraudulent transfer laws.

Also, an LLC is a business entity and needs a business purpose. Ihould not own personal assets because it will just be treated as an extension of yourself since a business has no reason to own personal assets.

you can contribute property to the LLC as capital. then the LLC owns the property and you become a tenant, pay rent, etc. while the LLC becomes your landlord.

the question is: “why?”
