The timeline for getting a conventional loan approved

[Eric T.]

I've been reading about the process of submitting an offer on a deal and all of the things that go on throughout that process. I'm a bit confused on the timeline for getting a conventional loan approved. At what point do you submit your application for a mortgage? Is it after you put in an offer for the property (but before the seller accepts it)? Or do you wait to apply for the mortgage after your offer's accepted?
