Clarence, I agree with Keith that a real estate pro should not be asking the questions that you are asking.
That being said, the answers that you have received are only as good as the qualifications of the 'real estate pro' that is writing them. Since info on Trulia is input by individuals, like yourself, you might want to check out their profiles before putting too much weight on individual answers.
Just a thought.
Proudly a REALTOR, with 20+ years of experience as a Real Estate Pro.
