The idea behind structuring it as a MMLLC (in this case my wife is the other member but it could be anyone or a broad syndicate as well) is that property will be held as a real estate investment entity. This investment entity will generate its own K-1 with the various income and expense (including mortgage interest, property taxes) that will flow to the members in the LLC. Because the entity will end up taking a net loss (due to expenses including mortgage interest, depectiation etc. net of rental income), this loss should flow to the members irrespective if they are over their personal mortgage interest deductibility cap. Because it is a real estate investment, the loss should be considered passive (and therefore can only be offset against passive income or carried forward). Additionally, because it is an investment entity and not a second home I own, I would think it may not be subject to the same personal use limitations.
