Good times and bad, slow or red hot, established realtor's will ALWAYS make money. Smarter ones buy up properties during good times that they rent out to help supplement their income during the slow times.
It's not a bad business to get into if you plan to be in it for the long haul. You can set your pace to be a busy as you want to be, and hire the quick buck dreamers during busy times, watch them dwindle during lean times. (your agency makes money from their sales regardless)
The realtor I use hardly ever goes out and shows homes, he just sits around running the office. He's sort of been retired for the past 20 years or so, taking life easy and doing a lot of fishing. Ask him if he worries about slow sales, bankruptcies, etc. He just smiles.
By checking the credit scores of the possible RENTERS. Fool me once, shame on you. Fool me twice--shame on me!!!!!!
Even smarter ones would build cash reserves in the good times to buy the properties during the slow times when there are bargains galore.
I'm not a real estate guru. Last house I bought was owner to owner without the protection money.
