I just got the email from Discover Card asking me to "Activate 5% Cashback Bonus Now". 

Locate your local RE groups via MeetUp, I've personally developed at least 4 great relationships over the past month or 2 alone (not just 4 business cards but people I can ask any dumb question I want)#5 develop your 5 to 10 year goals with real estate, this can change.

This week I am working on getting business cards and a letter head to market myself. 

And don't forget your business cards.

Also I got for my company Home Depot and Lowes credit cards using my SS but the cards are in the business name.

Their service is what most credit card debt collectors use to contact you.

Are you using post cards, letters, etc?

The whole portfolio potentially falls like a house of cards.

I made a very nice post card that I feel will at least get a quick enough glance to catch the name before being thrown away the first time and will be easily remembered the second time and on.

So the question you are asking is impossible for anyone in this forum to answer unless we knew exactly what his overhead was (truck costs, tool expenses, auto, worker comp, health insurances, rents, advertising, cell phone, marketing collateral, vacation time, credit card fees, accounting, software, office supplies, computer expenses, etc...) to name a few.
