If I’m really only looking for the lowest rate, is there a site out there that acts as a database and provides relatively accurate rates by lender if you provide an estimated credit score? NerdWallet had a few listed, but not a lot, and didn't see a ton of other options after a quick Google search. I would like to avoid submitting name, email, phone, and other information to 10 banks just to get quotes and have them blowing up my inbox and voicemail for the rest of time. Maybe that is the way it works, but I was hoping to steer clear of that if at all possible.
Edit: Also, I think we are buying FSBO and not working with a realtor, so don't have a built in relationship to a specific lender. And we will ensure a real estate attorney is used to help with the paperwork for the crowd that is going to come in here questioning not using an agent.
