And how is wholesaling brokering given; Wholesalers are engaging in contract trading for a profit margin(arbitrage) and brokers are providing professional services, facilitating transactions for a commission while obligated to act in clients’ best interests?

This is not only my experience, but when you call VRBO or Airbnb customer service, they will tell you the same thing.  

I'm unsure which focus would help me scale my portfolio and achieve my goals more efficiently. 

I’m also the founder/owner of Sabino Properties, a boots-on-the-ground services provider in Dothan, AL and the Wiregrass.  

Assuming you have access to MLS (Multiple Listing Service, a place for agents to list deals).1) Look for deals that look like investor-type of deals (e.g. low purchase price, ugly houses, or sometimes MLS will even say what type of financing it is)2) If the buyer's info is there, voila.  3) Otherwise, contact the realtor to look for leads (that will be more of a uphill battle, but you never know...)

@William GranthamThank you for your service and welcome to BP.

I didn't see a minimum DSCR (or Rent to Debt Service), depending on the lender.Because I run my business myself my expenses are little to nothing above and beyond my mortgage and escrow payments. 

E&O probably isn't needed unless you are offering advisory services. 

A typical PM for full service is around 20-30% depending on the area.Or do you mean a PM that is local to you managing your out of state STRs?
