i wouldn't rule it out unless you've really, really searched exhaustively. 

I use truepeoplesearch and then i exhaust all means on social media too. 

Once you exhaust a market and have mastered one, then it's a good idea to move to others as your business expands. 

In my case, we added the duct and when the tenant said it was too warm, we added a portable ac unit that has the wheels and exhausts the warm air out of the window. 

If you are selling a vacant single family home, I would think a buyer looking to live there would most likely value it more than an investor would, so if your marketing is more focused on attracting investors as an income property, I would also market it/list it as a single family home. 

People like feeling empowered, and I think everyone is feeling a bit exhausted of marketing & advertising.

I'm willing to sacrifice a few BPS to avoid an exhaustive underwriting process.  

Add addendums until you're exhausted.

And there is the universal omnipresent market immune opportunities of; Distressed/ Exhausted/ Novice landlord, Death & Divorce. 

so are you saying creating an s-corp will help to not get tagged as a dealer, rather than an LLC?
