Am advertising my single family house for rent now as the tenants will be out in mid-June.

It is advertised as a 10 cap  and the neighborhood is a C/D class. 

You're also likely to spend more listing FSBO than you might think, between advertising, your own time, and the dreaded holding costs.  

-How can I market/ advertise the property so I can get a renter in asap, or how can I attract investors looking to buy from me if I were doing wholesaling. 

I have family in the Midsouth which makes Memphis a nice writeoff location to review my property status and swing by to visit the family :-)I did not mention the name of the company because I was not sure how aggressive the advertising clause in our posts would be policed. 

Do I advertise the property for $90k?

you need to upgrade to pro to advertise your services.. however as one investor to another broad casting for deals on this open forum has its ups an downs... good luck

That's a $2,400 commission.  40% goes to the brokerage to cover overhead, staff, office lease, advertising, supplies, licensing fees, e&o, etc.  

I do a lot of SEO and PPC with Google Adwords as well as Facebook advertising for my own real estate investing and for other investor or business clients.

In talking to them it seems like they've probably called every investor that advertises on Craigslist.
