Mortgage Loan Estimate Review

[Dominick Ator]

Hi guys, so I'm working with a lender that provided me with a Loan Estimate and since it's my first time home purchase I would like someone with experience to take a look at it and give me their opinion. Red flags came to my mind, when he put on the estimate a 3.5 Interest rate and me being extremely well qualified I should be getting market rate. He then hit me with "Don't worry about it". Like can you please give me a good answer and ballpark?

I just don't want to be screwed on this first time home purchase. 

LOAN AMOUNT: $531000
HOUSE PRICE: $590K
Interest Rate Quoted: 3.5% (Credit Score 792, Debt/Income Ratio: 38%)

Please chime in I would really love the help.
