You have an obligation to be sure that the current tenant's belongings are secure.Most commonly around here, a Realtor's commission is 1 month's rent. 

Better commission splits but less training resources.

Honestly, she works hard and makes a nice commission.

Also if your buying off the mls the property owner has already agreed to pay commissions unless other wise negotiated in the contract so why not use the opportunity to find your own agent.

Your agent isn’t owed a commission until it sells.

In most markets, bringing a buyers broker for a commercial property will put your client at a big disadvantage (unless your client plans to pay your commission). 

From the day I became licensed it was approximately 6 months until my first closed brokerage transaction and saw any kind of commissions due to the license.This is where the "reserves" part of the conversation come in.

@Sam Besong Wholesaling as you are practicing it is illegal in Massachusetts unless you have a license to sell real estate.Here is Mass General Laws, Title XVI, Chapter 112, Sec. 87pp, describing the activities that require a license:"''Real estate broker'', hereinafter referred to as broker, any person who for another person and for a fee, commission or other valuable consideration, or with the intention or in the expectation or upon the promise of receiving or collecting a fee, commission or other valuable consideration, does any of the following: sells, exchanges, purchases, rents or leases, or negotiates, or offers, attempts or agrees to negotiate the sale, exchange, purchase, rental or leasing of any real estate, or lists or offers, attempts or agrees to list any real estate, or buys or offers to buy, sells or offers to sell or otherwise deals in options on real estate, or advertises or holds himself out as engaged in the business of selling, exchanging, purchasing, renting or leasing real estate, or assists or directs in the procuring of prospects or the negotiation or completion of any agreement or transaction which results or is intended to result in the sale, exchange, purchase, leasing or renting of any real estate."

I was able to continue this because I had great cash flow from my other rentals, w2 income, and my commissions from being a Real Estate Agent.

I am happy making $150k on a $1.5M sale price since I also get RE commissions on top of it.
