They may have a better product for you or be able to work some magic in your benefit.

That's really the only benefit I can think of because that's a great rate.

@Shaun R. there are several reasons but one primary factor could be the taxation status of the MGMT Co and any fringe benefits you may be looking to integrate

Ultimately the benefit of the credit line would be purchasing a second property, lower mtg payment, no PMI in exchange of another debt which interest rates will only increase through time...is this the right reasoning or did I miss the mark?

This is great advice, however, a cost seg will not be efficient on a single family home, the cost seg will likely cost you more than any benefit.

On one hand we bought the property, for all its risks and all its benefits and on the other, it was initially owed to the previous owner but perhaps was one of the reasons they chose to sell.

If you falsify the document to her benefit, could you give me your info so I can claim it on my taxes?

It doesn't seem like I would get any of the  tax benefits of a multifamily, so are there any advantages of owning 3 condos over a multi-family?

You should also include several other benefits for property #2: appreciation, tax benefits, experience, relationships, etc. 2.
