and for the life of me I cant see what these guys do that a very good RE broker who specializes in those assets could not do for you and far better frankly. 

An LLC when properly formed and administered provides separation and protection of assets that are outside of the LLC from the actions of the LLC.  

For many years I was contacted by the housing office to provide input of my rents, both Section 8 and market rented units and participated in their annual surveys. 

I’ve built relationships with brokers who specialize in Harlem, and one of them brought this off-market deal to my attention.

Many of these PM's have too much on their plate and are unable to provide you with consistent communication.

If you haven’t already, consult with an attorney who specializes in landlord-tenant law in Texas(sorry I have no recommendations here).

great advice provided - what I will add to this is if you have smokers and its not allowed I would offer to allow them out of the lease with no penalty. 

Spreading funds across 2-3 properties could provide diversification and steady cash flow.

While a properly maintained TN LLC might be sufficient for those who diligently follow corporate formalities, the additional layer provided by the Wyoming entity can offer significant extra protection, albeit with increased complexity and cost.

As long as you're living in it as your primary residence and can provide proof of that, you can continue with Owner Occ tax rate.
