Pros
If you just want a part time gig, this is for you. Could possibly lead to a position with a builder or, at least, that's what they tell you. You can learn about the new home industry.
Kontras
Having done this for over two years, I can say that you are treated with no respect. You can work hard, help get sales for them, and not even a thank you from management. I was told by Temps Plus, that after six months of working at a new home community, I should have no problems getting a job with a builder. Well, not true. Of course, that's my experience, and I am an older agent. I applied several times to the builders I temped for, and crickets. They use you, and overlook you. It's humiliating. A bigwig in marketing at one of the communities I worked at came in to the office one day (dressed very shabbily) looked me up and down and talked down to me, because I was the temp. My takeaway is this: If you're young and have some real estate experience but no new home sales experience and want to work for a builder, you have a much better chance getting in with them then an older person with lots of resale experience and no new home experience! If you're older and have mainly worked for a new home builder, then you have a good shot.
