Paying no commission and seller financing options seem to resonate with these folks. 

Might the agent be upset about possibly not making a commission on selling the house if it is a "subject to" transaction?

Made a nice $15K profit after commissions - property sold within 2 months of putting it in the market Lessons learned?

You've NOT paid retail...this is still an off-market sale... no commissions to realtors, etc.But wait...here's the part most investors lose sight of...Now you go find a good PM company, who will "take good care of you." 

I got licensed in nyc after my purchase, so I acted as my own agent under a broker and saved 9k in commission.

Being a new line of work and being 100% commission, I can't use this as a source of income for a home, hence the co-signer.The home is a lake-side property. 1.93 Acres of land, 1419sq.ft. single family home with 3 beds, 2 baths.

In Louisville, Kentucky as a wholesaler we cannot list the property on the MLS with a realtor so he/she can get commission if the realtor finds a buyer.

If I want to sell off my SFH rentals which may be more appropriate for actual home owners instead of investors (based on <5% cap rate) is trying to work with wholesalers still a good idea to avoid the high commission % or just list with retail?

All you have to do is set your prices to account for their commissions or added on as an admin fee which is what I do. besides, they offer a lot of functionality and I'm not for sure why your  time is so worthless that you try to compete with them.

I have buyers and investors), cleaning & hosting open houses, and reduced commission promo period)I have a few friends in the neighborhood that I could post my sign up out front on high visibility routesAdvertise on Zillow (this would be new to me)Anything else would be greatly appreciated.
