I was meaning to post this a while ago, but these are the notes I took when I was shopping for a mortgage and closing the purchase of our first house. It was quite a process. As a first-time borrower, I felt like I was at constant risk of these expert lenders taking advantage of my naiveté, especially given all the stories from mortgage crisis. So, I spent a lot of time reading and double-checking. I try here to lay out what I took away from the process, without biasing it toward any decisions my wife and I made pertaining to our own situation.
Disclaimer: These are the notes of one person (me) who has bought exactly one home with exactly one mortgage. I am not an expert. I have no qualifications. I’m just a dude. This might be useful as a starting point, but I highly suggest you do your own research and confirm your conclusions with advice from an expert you trust.
