just asking

I have always had a intrest in selling real estate and dont know ho to ask or what to ask really so since none of you know me lol ill ask here. how much money dose it cost approx to go to school etc to get a license?

how long dose it take?

do you have to have a high school diploma or ged?

how do you handel the fact that a bad person can ask to see a home and then esp if a lady is showing it what if they try to harm her once they are inside the home alone? can a agent carry a gun on them?

if a agent works say for century 21 can they sell property and get the comission on the side like a side job if they on their own find a home and get it sold do they have to pay their boss even if this was a privet thing between them and the seller and buyer?
