My husband did NOT renew his realtor license this past winter because of the terrible economy right now. In a nutshell, I'd really advice you to think of a plan B.
My husband was with a reputable, well known company for the last 5 years and he made very little as a full time realtor. You can't count on friends, family, etc... to use your services because they seem to know several others who are also realtors. Then there's the people who will just call you and ask you all these questions about a house, neighborhood, etc... You'll show them 20 homes (seriously!... if not more) and then they'll decide they want to wait a couple of years before they actually go ahead and buy. Meanwhile, you've added wear and tear to your car, paid for a lot of gas, used A LOT of your time, AND not get paid ONE PENNY!
You'll also have people who want to only go the short sale route and/or foreclosure route and these two ways add even more work, and don't always amount to a closing. The inspection doesn't pass, the offer wasn't accepted by the bank, multiple offers were given to the bank, and your clients was rejected, etc...
Okay... I could go on and on, but it's late and I need to get to sleep. My husband always went the extra mile with his clients, but it created stress (at times) for him and little money. My husband was awesome with his clients even though he felt he was being "used" quiet a bit. (He worked from home sometimes and always had his cell on.... even a 9 in the evening! (He sounded great on the phone as he talked business with his clients.)
Yeah... you'll have people who will want to interview you and a few other realtors and then, you'll see a "For Sale Buy Owner" sign in their yard. Hmmm.... perhaps they were getting ideas on just how much to list their home and other ideas from the professionals. You'll have others call you several times from the early morning (yep... some called at 6:30 am!) to very late (almost midnight) and you'll answer all their questions, take them to several showings, but then they'll decide not to buy or not to sell. You'll have clients who get frustrated because their house isn't selling... not even getting a "nibble." But... it won't be your fault, you'll have told them that their asking price is too high for today's market. They'll think their house is the exception. That their house offers so much more than the neighbor's house down the street. etc....
Maybe there are some realtors that are doing alright in this economy, but my hunch is those are the ones who have been in it for SEVERAL years and have been very much established with client referrals from the past.
Good luck to you and your husband, if you decide to go this route. Well... gee... after all my venting, I think you can tell how I feel about this subject:-)
