I got 2 lenders with 2 very differaent rates: What's up??

[Jay Welch]

Trying to buy a house at 339k. Salary 110k and FICO 629. FHA loan. I applied with two well known local mortgage lenders. I got two very different interest rates/offers:

#1:  3.5% down, Interest rate 4.625%.  Monthly payment=$2740

#2:  5% down, Interest rate=4.125%.  Monthly payment=$2450.

I'M CONFUSED!  Do these both sound legit?  Thank you!
