I was in the business fulltime for 4 years before my husband came on FT. He had gotten his license 1 year after I got mine to help in the crisis. He was working for a company we knew was closing and basically waited for them to pay him to leave (severance package)....
Pros-
When you have been standing in line for 45 minutes at Chilis for a table and someone calls and wants to do another walk thru on the house and then write a contract- he gets it and understands with no complaints.
He helps when all the balls get up in the air. When I cant be in 2 places at once - he can go where I cant.
Cons-
At times We have a hard time figuring out my role and his. Also, he sometimes has a very hard time taking advice from his wife. There have been times that I have had someone else in the office tell him something and then he listens.
Since we are both in Real Estate sometimes it is the only thing we talk about. We have had to have Real Estate Free Dinners. We have to make sure we schedule times to just be a couple and not a couple of real estate agents.
This is just a couple of pros and cons. In general I really am glad we do this together. He gets what I do. I have friends that have spouses that dont get the weekend work or the evening work. I dont have that. We are also really good together because my strengths are not his and his are not mine. But there are days when I look at him and think I really just cant see your face anymore today.

Good Luck!
