If I purchase a home, less than the loan I received, Should I return the extra to the lender?

You need to expand on your question. Purchase price minus down payment equals loan amount. What is there to return and why?

When you get a loan, the lender will issue funding based on the sale price or appraised value, the lower of the two.. you would never get more from a loan than the property is worth.. and besides, they don't give YOU the money directly.. There is always a 3rd party involved (title company or attorney's office), who will distribute the funds as the lender directs... I'm a Broker here in Scottsdale AZ and I only lend in Arizona.
