The position's that we put our families in when we push the limits to break through to the next level.  

Now you are positive :)2) Decrease Maintenance. 9.6k looks like too much, probably I am going a little bit high in this number.

My primary concern is the changing nature of renting a unit in a building whose units are being converted to day rentals, comparable to Airbnb.

We also attempted wholesaling "in-house" only to find this to be impractical with our demanding, full-time jobs.Our primary interest is SFR rentals in the Jersey Shore/Central Jersey area with flips to pay these down faster.

My husband and I are finding ourselves in a similar position and are not sure what the best course of action should be.  

You know, cause I understood her position and maybe next time. 

There are no programs that allow less than 20% down on 2-4 unit purchases unless you are asking for an FHA loan for a primary residence.  

my primary home to my LLC (that already contains 11 uniits) without losing my Section 121 benefits (capital gains exclusion)?  

Pretty much what @Mindy Jensen is saying, but don't cash it out just to do some rehab on your primary is my two cents.

Being in our position is great because we are agents.
