Deb,
Your total GFE cost is pretty standard. If you're in a state that requires an attorney and your GFE includes hazard insurance, tax escrows, title, closing, lender fee's your in an acceptable range. Also if everything isn't final number (actual title company costs, daily interest, insurance) then it may go up or down.
As far as your rate goes because your loan size is smaller I would expect to see .125% to .25% higher interest rate simply because compensation is based on percentage. The previous post stated some expected totals based on the rates you were quoted but that only assumes your broker has access to the best lenders at all times and your loan is being underwritten at the best rate investor (which changes from day to day).
Compensation is fully disclosed now and more than likely you've signed something that says the expected range your broker would change, either upfront or in combination with yield spread/release premiums lenders pay. If you have questions just ask your broker how much compensation they expect to make on your loan (such as 1% origination and 1% back end premium). Then ask what rate you would get if you paid 2% origination and they locked you at par (no premium paid from the investor). For example today I would quote 5.375% paying 1% premium (by the way 5.625% only pays 1.50%) and 1% origination. For 2% origination I would quote 5.125%.
Since your loan to value is around 75% you won't sacrifice anything to your rate or loan by putting $1,220 less down and getting a lower rate. In the long run you'll save more money.
Have a great week
