I always assumed that an internet poster who would use a Vehicle Code section for a moving violation as their handle was a CHP officer or something like that. If so, I’m a little surprised you would ask how to commit mortgage fraud, which is a felony. If not, then that’s what I get for making assumptions.
A purchase of that house at $350k may or may not be a good long term bet, but it’s a sure thing compared to risking everything good in your life for a slightly better interest rate. I sincerely hope you reconsider, ’cause I don’t want to think of you like that.
