We use preprinted signs that are a yellow background with red lettering. 

we bought our first house in VB, the red mill section.

Does anyone have additional advice of what red flags I should be looking for?

Late last night I was catching up on several emails and enjoying a delicious deep dish pizza when an idea popped into my head for real estate investing - Be Bold...Be Loud...and Be Proud!

Bright reds and blues seem to be popular at this time.

How did you know it was a deal (what signs sent up red flags on the current property manager, what did you look for)? 

I was feeling some red flags with wanting to draw things up without my input.

Too much red tape and too many hoops to jump through.

That raises a red flag , unless he has a relative or won the lottery , I'd pass and hire a realtor to assist me. 

If there are red flags on your proof of funds and the other agents or sellers don't know who you are, then even though your bid may be slightly higher or very similar they may take the perceived "lower risk" option.
