ALWAYS have business cards on you.

That won't be until Nov or Dec.Swanny  Thank you for taking the time for the detailed reply it is much appreciated  Wow I have to be honest reading through that is like reading another language I have no clue what so much of that even means  I started with a single family house bought with credit cards  lol.  

The "house of cards" was going to come down.

Also where did you get your post cards, how much did you pay for them and what did they cost to ship?

Bring a business card with your name and address and introduce yourself.They're going to be your best source of referrals and your first line of defense against problem tenants. 

That's exactly, what I am doing, pay off my credit card debt (which isnt too much, about 1900) and paying my student loan on time.

Tell everyone you meet that you are an agent, get cards made and hand them out.  

Business cards, websites, social media presence:  these are all simply marketing

I just starting out (again) into RE investings and starting of with a direct mail campaign using post cards.

If you have 20 units or 20 SFH you have 20 different due dates to remember, 20 times pulling out your credit card every single month.
