Shoudl ask a mortgage broker. 

No idea. 

Very. In new construction the Borrower is married to me for a year, we exchange information and I guide them to completion. Existing sale or refinance it's an intense short term 20 -30 day relationship with emails and greeting cards for holidays after.

They are paid out in stages referred to a construction draws with interest only payments and repayment in full is normally due after all payouts are complete. In recent years some loan types are referred to as construction to permanent. 

Temp to perm construction financing is absolutely different from a conventional mortgage. That's where interim financing is followed by permanent financing once the home is completed.
However, some banks can do a one time close. You should Google these and look into it.

There can be numerous nuances of differences among mortgages whether for new construction or resale home.

That is a good Q for a mortgage lender.

I wish you all the best with your real estate studies. 

Are you talking about a property that is already built or one that is being built?

there are many mortgage people here who have that answer....

They are very short term and granted with the understanding they will be paid off quickly or rolled into a typical mortgage once the work is done kennith Frazier 

Talk to a lender about this one.

There can be many different structures. Talk with your trusted local mortgage loan officer who deals with contruction loans.

Agree with Nina Hollander 

This is a great question for a licensed mortgage broker Kennith. 

They are not. But I suggest you ask a mortgage lender.

I am a REALTOR, and don't do mortgages.

In my experience, not that different.  Of course the homes were built by the time my family bought them.

Vastly different!

They are a 2-part process with the first part being broken down into draws paid to the builder as they get through each stage of the building process.

Once a CO is obtained and the final draw has been paid, the home moves into the 2nd part of the process which is the final, permanent loan (like a regular mortgage).
