Minimally... I refer my clients to the right lenders to educate them.

Where's the loan guy? Siesta? Why is the agent being blamed for this? The agent's not the loan guy.
We need to know enough to be versed. But the buyer needs to be in contact with their mortgage professional from the onset, and fully clued into the process from start to finish..

I usually leave any mortgage questions to my lender.  I connect them from the beginning of the process.

I have the loan officers I use explain the entire process!

I use really good lenders who do all that.

None...I send them to the proper professional for the correct answer.

Thanks for the Q, Praful Thakkar. You have received several excellent A's.

I'll run some hypothetical #'s through my mortgage calculator for a buyer; if they want a general idea of what the payments may be. That's about as deep as I get into the mortgage part of it. 

I make it crystal clear that I am NOT in the finance business and I tell them who I think is the BEST in that business. I let them know that I work with that person very closely and trust them completely. It is in the Buyers best interest NOT to get financial information from me just as it is not in their best interest to get Real Estate information from their banker.

Usually I don't. But i'm able explain the basics of financing. For more details we call the lender. 

 I let the lender handle all of it.

This is part of the agent's job.

I leave that to a licensed mortgage broker Praful Thakkar 

I don't. I have trused mortgage/lenders who do this. They are the experts in the field. I've got enough informaton to cover the subject but I want them speaking to my lender. 

I like to let me buyers know from the start what to expect. I look for the Loan officer we choose to work with us and do the same. A rate lock with new construction is laughable unless already built. They should have known this up front from the loan officer

I do discuss rate locks with buyers and most certainly discuss this with buyers who are looking at new construction.  They have to be made aware of it ... from there it is between the buyer and their lender. 

If my clients have loan questions I get them in touch with one of my trusted loan officers.  I don't feel qualified to answer questions that can be very different based on credit scores and loan types best suited to that particular client.  I might answer some general questions about "how fast can we close? does anyone do loans on these lease properties?" but beyond the general questions I refer to a specialist in the field.

I do an intro but rely on pros.

I have a packet for various stages of home buying with documents and videos

I just refer these things to a lender.

I try to let my lending professionals do this, but do check to be sure they locked in their rate.

As a Mortgage Banker,this can be one of the most frustrating parts of my job. Most borrowers get their information from Aunt Mable and Uncle Harry. Of course the neighbor is probably the "final authority" when it comes to rates, terms, FICO's, locks and etc. I just try to explain that with the changes, laws, regulations and verifications, mortgages are vastly different then when Mom and Dad moved into their home!

Praful Thakkar This is why I put them on to a lender as soon as possible so they can answer these questions.

A little, but typically I leave this to the experts.

I let my preferred lenders do that.

covered  in Buyers Consultation Session

Leave that to a lender

Suggest they talk to a lender.

All  the time Praful!

I give them a general overview but tell them this is something they must discuss with the lender.

Only when asked...I outsource that
