Online Mortgage Lenders for Conventional Loan w/20% down?

[Duane Gunkler]

Looking for input on best options for an investment property (2/2.5 Townhouse) that I went under contract on today as a buy and hold.  I will be putting 20% down and am looking to go with Conventional financing.  I have started working with the mortgage broker my realtor recommended, but would like to get at least two other offers to compare.

Mostly curious about going with a local person vs. some of the online sites, like Rocket Mortgage, etc.?

Thanks in advance!
