I had thoughts that "legitimizing" my business would be a smart first step.a.k.a. making a website, having business cards, getting a separate "business" phone/voicemail to answer prospective leads inquiring about properties or offering them.Would anyone suggest that this is the right direction to go before spending money on direct mailing campaigns/driving for dollars/running advertisements via craigslist or any other source?

On the other hand, I've never budgeted or paid for advertising as part of a single property, so maybe that's all a wash. 

We ended up hearing an advertisement on the radio and went to a seminar.

Is the FB campaigns paid advertising?  

Otherwise it should be advertised as two units.  

Advertised a rental here but have not sold it.

Tell your family and friends what you do to see if they are interested, if not start advertising your deal, if it's a good deal you will find cash buyers and most likely a private lender as well Another way is to run ads looking for private money  to score a good deal Good luck @Brian G.

She just got stuck in a rut and I finally had to let her go when she rented a place for a year at $35 dollars a month below the agreed/ advertised price.

I am starting to market my company and advertise and brand my name, to start something new that will be built into a huge corporation one day doing millions in revenue a year.

First l advertise cross streets a block away never exact address, second if someone call I will pre-screen them over the phone; does the price work for your budget, what do you do for a living, can you provide paystubs, can you pass a background check etc. then because I use lockbox most times I never give the code until first they send me a picture of their drivers license and second they are at the house with the lockbox in there hands to prevent them from even writing it down.Also they must call me back as soon as they are done looking before they leave the property for security reasons, make sure the keys are back in the box and combination is shuffled and of course to tell me what think about the place.
