Primary home is a little easier but for FHA and other programs it requires 12 months title seasoning.There is something called delayed financing that if you purchase a piece of land and pay for the home "All Cash" without a mortgage you can get up to 80% LTC.

No, you cannot purchase a home with an FHA loan via an LLC.

I purchased a 3 family in Newark NJ in March of this year, and am curious about looking into this form of insurance as a way to further protect myself. 

Some may have very small thresholds for repair holdbacks on purchases but this is typically limited to make ready items not to exceed $2,500 in costs to cure.
