But it was like $200 a year and $200 per sale/buy when a commission is made (so $0 unless you're doing a transaction where you earn a commission)My guess is there are tons of those in San Diego. 

Your best route would be to team up with an experienced commercial agent within Keller Williams, let them have the lions share of the commission.....you’ll learn and more importantly you won’t miss something that would cost your client dearly.....commercial is a Whole different game.

I live in a market with a ton of new construction and expect when the market softens builders may offer stealer deals to offload inventory and pay 5-8% realtor commission that may make new construction a decent option (it this scenario happens).

So because I went to visit him at that open house, I got two great deals (well, one deal and one very large commission).

Multifamily brokers certainly earn their commission and it is worth working with them.

Learned a ton and now I want to try to flip another house, and this time I'll know what I'm doing.At the end of it we put about 12000 into repairs. closing was 13000 with commissions, hoa costs, home warranty etc.

For option renewals will there be leasing commissions owed?

You should be seeing some cash-flow if its a 1% deal.If you sell the property now - the gain isin't so greatSales price $85,000Less Commission of $4,000Less Misc Closing costs $2,500Less cost basis of $68,500Gain = $10,000You then have to pay federal income tax(STCG) which is your marginal tax rate.You also have to pay income tax to Indiana of 3.3%I don't know what your marginal tax rate is but you are giving up the cash-flow for maybe $8,000.I would personally keep the property. 

No conversation gets brought up regarding procuring cause. 30 days after COE listing broker says there’s an issue with procuring cause and wants 2/3 of buyers agent commission.

So if you sell something, you get a commission and your realtor gets a commission.
