My point is...invest within your means and plan ahead so you don't lose your shirt in a recession.

Then again, I've been there, done that, and still have the T-shirt so don't let me dissuade you.

If you show up in sagging blue jeans, a T shirt and a desire to argue with your potential client, you are screwing yourself!  

He already owns T-shirt inventory in China that cost him $5 million which he purchased with his personal funds.3.

They all were wearing plain khaki paints and simple dress shirts.

I do recommend reading the BP tax book http://get.biggerpockets.com/taxbook/ I own a copy and felt it was very helpful.As for book-keeping I use an app called Scanbot, which automatically date stamps and writes the location into the file name of the PDF, which it automatically syncs with my Google Drive Receipts folder.

I had shirts made for advertising "I BUY HOUSES." 

My other clients are sellers so I do a polo shirt and nice shorts or pants.  

I'm a licensed architect, just got my stamp this February, so I can confirm that the salary we get isn't much to shake a stick at.

Hit the postoffice and buy a roll of forever stamps $50-$55/1005) Hand write 5 letters every night to the property owners saying who you are.
