@Michael LeBlancDeciding when to establish an LLC (Limited Liability Company) for your real estate investment, especially for a house hack, involves considering various factors.

Typically, you just require that the property be vacant for closing.

I am also going to required annual increases in rent based on the CPI index, among a few other things.Does anyone have experience with this?

but, we do have a work around for this in the states we lend.For non conventional products it is up to the individual program requirements.  

Also, was agent required for it?

No idea on the notice period required, depends on your lease and your particular state laws. 

The larger property will be required to be held in an LLC.

Any insight or knowledge would be appreciated this way:  A mortgage and note do not, in fact CAN NOT legally prohibit the sale of the subject property; nor can that document REQUIRE the announcement of that sale.  

It will require 15-20% down though as others have said.

You can file annual reports as required in each state yourself and pay the fees.
