I have no credentials (disclaimer) but my opinion having used LLCs and LLPs (similar) for 7 properties:1) I believe it is best for an LLC or LLP to be organized in the state in which the properties reside.  

I have a degree and post graduate work at Yale, I do not drink or do drugs, BTW, I was simply over qualified for what was available. 

I'm waiting until I pay off my primary residence and will likely put 50% down or something along those lines.I've heard that a single family will appreciate the fastest, but has more of a hassle factor in terms of managing it.  

Does anyone know a qualified person?

Before you start you might ought to get a pre-approval loan letter from your financier that states how long it should take to close that and the maximum amount you qualified for.  

Is there a reason why you wont use the proceeds from your primary residence refi as your down payment for the second rental? 

There's a lot of charm downtown but those MFR are laid out a little weird and could present issues with young residents.  

If you can provide affordable home ownership opportunities through lease options to those who don't qualify for conventional financing and don't meet the requirement's for the housing complexes... you have leverage.

As your Residence, in two years you get to sell it tax-free.

My goal is to qualify a Tenant Buyer and then Assign my interest to the t/b while collecting the Option Consideration.
