My current strength and key focus is on deal analysis.

Not done yet.. you need to figure out the strength of the lease.. absolute/true NNN is the best.. years till expiry, how new the building and yearly increases impact how close to the market cap rate the building should be..

How best to use it will depend on your goals, you need for cash flow, your risk tolerance, your overall current financial situation, and your personal strengths and interests. 

Go a step further and ask them why they are referring a particular contractor, and the contractor's strengths and weaknesses. 

You both may know what each other's strengths and weakness are and if he has a good network and can bring qualified leads, why not use it.  

Unfortunately with iBuyers like ZillowOpen, OpenDoor, and more - many properties that were good finds for investors are now being purchased with cash by these deep-pocket corporations and warehoused.I recommend finding a realtor who works with investors to add bench strength to your search.

Each have their own strengths and weakness:Zillow: Free and popular. 

@Zak BocaPartner with someone in Commercialreal estate in a way you both can leverage your own strengths if you wanted fastest and easiest route in..

Knowing your why is crucial because this gives you the strength and purpose to keep going even when opposition stands in your way.Take complete responsibility for your success as we;; as failures in your life: Successful people do not play the victim role.

The key is to expose yourself to as many different possible profitable avenues in real estate investing & then continue to narrow them down to a select few which would be a good match for your strengths & personality.
