Welcome to the wonderful world of real estate; the BEST profession in the world in my humble opinion. Starting out you want to keep your expenses to a bare minimum. Depending on your sphere of influence it may take you quite a long time before you can count on a regular stream of revenue. Many agents never get there as this is not a business for those who are not willing to give the attention it requires to be successful.
The best advice I can give you is get face to face with as many prospects, both seller's and buyer's, that you can. I know agents starting off who have been very successful knocking on doors of FSBO's. This in my opinion is the most direct approach to success and one I would recommend.
If you do not have a copy of "The Millionaire Real Estate Agent" by Gary Keller, RUN, don't walk, to your local bookstore and get a copy. Read it, highlight it, re-read it and live it. If you put 100% into this business you are in for a fun trip, if not you will probably soon be looking for another profession.
Best of luck and again welcome to the wacky world of real estate!
Always at Your Service,
