Hey Walt,
If you want to see what difference a loan broker can make to your costs here’s a least effort method:
1. Goto zillow.com’s Mortgage page.
2. Enter your loan details on the left of the page.
3. Click “Get Quotes”
4. Sort by “Total Cost”
5. Compare the lowest “Total Cost” with the highest “Total Cost”.
For me the difference was ~$20k over 10 years. More than your measly $12k, right.
(Plus the Present Value of ~$20k over 10 years is what, ~$24k…?)
Kudos to SDR, Walt, why dont you have a stab at figuring this crap out yourself first?
