If this is a potential buyer, consider yourself lucky that they revealed their realtor status up front. Most of them wait until we have a lot of time invested before they reveal their agent status and their need for a referral fee. 2nd home market

I would find out what info they want then decide how to proceed. 

Call them back, find out what they want, and proceed from there. Always return a call, no matter who the person is. One, it becomes a habit, and two, you never know where it leads to.

No, not right off. I would reply, provide the information, and see if I can help them, and see where it goes.

As a professional courtesy I would find out exactly what they need/want. If I can help in 10-15 minutes I am happy to assist. If beyond that ... we talk about how engaged I will be and how I will be paid.

 Depends on the questions that they have .....

David,
Just call them. I assume they are legit until it appears otherwise.

I have a Broker(not active in MLS) who occasionally calls for information on a home; as long as I have no expenses I will give him what he wants. If there will be expenses it is discussed first.

If relavant to the property, i.e. "Is this a single level house with no step downs or up?" I would respond.

Hey, what's happened to my profile image?

Are they inquiring about one of your listings, or a reciprocity listing, or ?
Are they inquiring for themself, or a client of theirs?
Are they local or not local?
I am inclined to extend professional courtesy if no red flags.

Given that this person disclosed, I think you should call and talk to them.  It is courteous.  A

Is the individual calling as a buyer or on behalf of a buyer?  Either way, to represent your seller properly, the requested info shoul be provided I would think, if the question is legitimate.

As a professional courtesy I would find out exactly what they need/want. They might be wanting a good responsive agent to send a referral!

I think it all depends. If someone has genuine questions and an interest a listing, I will provide it.  If someone is trying to use me to get access to homes and information about listings because they don't belong to "that MLS" and they want to show homes in that area, I will be limited in my responses. 

I like Kathleen Daniels answer.

Find out what they want.  It's not unusual for a local agent to contact you, since their client might have sent them a link to your website, and it's quicker to fill out the form then look your contact info up.

But, if they're outside the area, treat them like any new prospect!  Q&A, agency agreement, etc.

 People who calls me asking me be the door opener and they can handle the negotiation often.  I bluntly tell them we do not operate that way.

If they are not local, I'm happy to help them. I never require a reperesentation agreement from any website lead on an early contact, why would I from another agent. I've sold to relocating agents lots of times.

I don't require anyone to sign a buyer representation agreement in order for me to give them information.

Are they an agent in another state?  I don't understand why you would try to convert an agent into your own client otherwise.

Typically I provide the info.  Buyers agreements haven't been big with me.

If they are asking about my listing I will treat them as any caller.  If they want info on iother listing I ask if they want representation

On the phone, I will provide the information they ask for as if they were the public. 

I ask if they plan to write the offer themselves or if they are looking for a referral and/or representation and go forward from their answer.

I would be curious what they wanted, and work from there.

I had similar requests, usually it is a waste of time. They do not access to MLS info and want to know something from you. I'd suggest that agent to call you. 

No. I would allow access to the needed information.

We do purchase houses for our own account. At some point in the process we need to disclose that we are licensed agents at least in most states we do. In addition we often will want to use a portion of the commission to offset closing cost for our transaction as well. 

Treat them as you would another agent representing a buyer.  This time they are one in the same. 

David - I think it would depend on exactly what information they were requesting, and how they wanted me to assist them. I would have to ask them a few questions before figuring out how to proceed.

You don't mention whether the REALTOR is local or not.  I probably would provide and hope for referrals.

It is not really a lead.
