Caution
The business side of real estate investing is fraught with risk. Unlike purchasing mutual funds or savings bonds, with real estate, you can lose money; this is one of the reasons that seasoned real estate investors caution neophytes never to get too emotional about a property and always be willing to walk away.
Throw caution to the wind and just do it.
Every step of life shows much caution is required.
I have learned to use the word "impossible" with the greatest caution.
Do not count your chickens before they are hatched.
Beware the wolf in sheep's clothing.
Sane and intelligent human beings are like all other human beings, and carefully and cautiously and diligently conceal their private real opinions from the world and give out fictitious ones in their stead for general consumption.
The cautious seldom err.
