You can use MLS Advantage  if you are a member of Florida Association of Realtors to view almost any MLS listing in Florida. 

     However, you cannot input your own Listings into MLS unless you belong to that particular MLS.

     The largest MLSs in Florida are Miami Association of Realtors, and My Florida Regional MLS.

While you can by law, logic says you should not attempt it! Make the referral!

I am not familiar with Florida, but in Ontario, it is possible to join up to multiple real estate boards and access the local MLS through them.  Also, many boards allow access to a subset of the features to other boards via various agreements.

I don't know about Florida but I do know that in New Mexico we are licensed to sell all over the state however, in order to have MLS access to certain areas outside of local MLS, my Broker has to become a member of the MLS in the county I want to become active, from there I also have to become a member in that MLS county. You have to pay for the extra MLS access. You can call your MLS board to get details and then let your Broker Know where you want to venture out to, and see if he/she is willing to become a member of that MLS to help you.

I like the answer provided by Fred Griffin. 

Linda Burgin You will have to join the MLS for he geographical areas you wish to work in your state. Shouldn't be a problem with your broker, but I would recommend you not work outside of your local region. Looks like Fred Griffin also has a solution.

Fred Griffin appears to have the answer

I would form relationships with referral partners in other areas. And what Fred Griffin said.
I can sell all over AZ too, but why? It is a big state. I can't be everywhere at once.

Very few Agents succeed as Generalists ! You neeed to become expert in a very defined market !!!

That is why we make associates here on AR and give referrals!

Good morning Linda. Yes, you can list and or sell throughout the state, your listings that you get will need to part of the MLS system you are part of.

I'm in CA, so I would not know, but the local mls i belong to, has accesses to listings of most local mls, commercial, and national listings. Yet, why would you work in the area you do not know, unless your client is an investor or/and you are willing to travel. 

I can legally represent clients in selling and buying real estate all over my state.  However in practice its not a good idea. I don't know about values and local regulations and customs and how to find school information of areas I don't work in on a regular basis. I would be putting buyers and sellers at disservice to try to do so.  

Yes you can.  Your license allows that.  But it may not be the best thing for your client.  Different parts of the state can have different customs.  For example, termite inspections are common in La Crosse.  10 miles down the road, they've never heard of them.  In La Crosse, we have title companies that do all the work.  Across the river, lawyers do it.  It would be better to refer and get some money on the transaction, rather than risk making a mistake and getting a commisionectomy.

That depends on your connection and broker membership with other regions.

I was licensed in Florida and yes you can sell anywhere in the state but unless you have a specific buyer elsewhere my experience is that you are better off sticking to your MLS and local area.

It's the same as CA where we can sell throughout but to list we need broker approval for local MLS access

This is clearly a question your need to discuss with your broker for guidance.

Our mls covers a very wide area.  If I have a client outside of that area, it's better to do a referral to a local agent.

Linda,
Are you competent all over the state? You are just asking to get sued. Also read the comments by Joan Dickie and others.

State license and the mls are two different things.

I serve 40-50 mile radius of Dayton, Ohio where my office is located.  Anything outside of that I am happy to refer the business to an agent who is qualified in that particular sellers market.  As far as that goes, I look for business outside of Ohio with my family & friends and get a 25% and sometimes a 30% referral fee.  If you build a real estate team across your state could be way to get this done.   I would love to hear how, if anyone is able to list in their whole state without a large team effort.  Technology is growing so fast but I still like to physically shake my clients hand.

There are some ways you can look at listings from out of your local MLS coverage. (Florida's MLS advantage for one.)

But, ask yourself if you're really representing your customer's best interest if you start working out of your local area.

Then you must join other or or at least one more MLSs so you can serve your clients well

Just because you can doesn't necessarily mean you should.

Your broker and your E&O insurance may have rules.  

Your broker would have to join all the boards where you would want to join.

With a license for a Florida Real Estate Sales license, you can be paid for assisting in the purchase and sale of real estate anywhere in the state.

To solve your problem, you can"

1. join every MLS in the state.
2. Rely on the listing agent to provide access, they WILL expect compensation.
3. Do something else
4. Ask yourself, "Who overcomes this problem EVERYDAY?" They have an answer, but may be reluctant to share it with a realtor.
5. Modify your plan to do the 30% thing.

I do not know how you describe your business or have knowledge of the content of your business plan. What I do know is new solutions are available to those entering real estate today expand the options available.

These options are presented to 'I thinking about real estate' folks before they enter the school. It may be too late for you to adapt to the emerging model.

I would suggest getting out of the box and seeing all that is available. Then exploit the opportunity the MLS, franchise brokers and NAR created by not protecting the participating agents. 

the otehrs have answered the question.

And why would you want to work all over the state? Learning to refer makes the most sense..you can't possibly know all the nuances of the whole state. If you still think that is the right choice than join the boards of all the cities..wow could be an expensive proposition.

Good morning Linda Burgin You have already gotten several good answers to your question.  I can add that I referred by parents home to local PA agent because it was one & half hours away.  Too far to service properly

It would be very hard to sell where you don't have MLS access and why would you want to? How can you truly represent the best interests of your clients in markets you are not familiar with? I am licensed in all of North and South Carolina, but don't sell throughout the entire states. And my mls actually provides all the listing data for NC's mountain area--but I know nothing about it, it's two hours away, why would I put myself out there. Better to send a referral.

Check with your board.
