A loan origination fee typically is 1% of the loan amount or one point. You always have the option of paying a higher rate in lieu of the fee or a higher fee to buy down the rate, discuss this with your loan officer. The points charged will vary depending on the loan amount. The processing fee will vary a little by broker but is to pay for the processing of the loan file as it is submitted to underwriting. Closing and settlement charges are third party fees for escrow and title work, this will not really vary by lender although good faith estimates might show them quoted low to entice you :) Ask lots of questions!

PMI is Private Mortgage Insurance same as MI (MIO i think is a typo) you will have this if your loan to value is over 80% unless you are taking out a VA or USDA loan.

Funding fee is required on FHA, VA, and USDA loans.

Good Luck!
