However, now that I have my primary residence paid down a little more I am interested in giving myself more financial freedom in the future and I am interested in buying and holding multi-family properties.

Would it be Advisable to sell other assets or properties for a  multi family that cashflows really well?

We are renting a house from a private party.

I just bought a multi-family in tenant friendly MA.  

Hello All - New to Bigger Pockets and looking into multi or single family homes.

I'm really pumped to have this play out the way it did, and learned from it.I'm considering forgetting my conventional mortgage and getting a commercial mortgage and purchasing a multi unit property instead of a condo.

I have been on all sides of construction, so that part is where I am most knowledgeable.The appeal of cash flowing from a rental is nice.

In the video I show how I end up replacing most of the suggested comps with comps pulled from Redfin and the justification behind it, but the punchline is that it helps you come up with an accurate number doing what @Hem Kumar said: "...make adjustments for unique features and amenities..."

I recommend multis would work better because taxes are so high they kill cash flow. 

I'm currently searching for my first purchase, a small multi-family.
