So $788k. Assuming 20% down that’s equal to $4000 per month payment. Subtract your writeoff (approx. $1600) is equal to $2400. Add in taxes & Mello Roos ($1000) and you are at $3400. That would rent you a very nice house in 4S Ranch (or more so areas by the beach). Not to mention the $470 in interest you would earn (after taxes @ 5.5%) on the deposit sitting in a savings account.
