I read each and every page before I purchased my home. I highlighted everything I didn't understand. Most pages looked like bumble bees. I worked questions during a 5 hour session with my realtor. For terms I now understood but didn't agree with, I had two options depending on the type of term it was:

1. Government and HOA stuff was not changing. I could accept it or walk.

2. Seller stuff could change. We made some minor requests and largely got them.

Reasoning:

We were spending 6 figures. The quality of my work would have a major impact on my family for a long time to come. I was newly married and this was my first family related big project. I was damn sure going to understand how interest rates and loans work ("whats a point?", "fixed vs float") and what legal junk we might be getting into.

I got a chance to learn a little about real estate. When life throws you a stack of legal documents, make lemonade.

I also got to vet out the agent. I work hard and have had some business success. I figured one day it would be time for another house and it would be nice to have a long term relationship with a trusted realtor on that one too.

Core point: it is your name on the document, it is a lot of money, it impacts your feature. Exactly how lazy are you to not read it?
