What is your current interest rate and how much is your PMI ?
Did you get an FHA loan or conventional ?
If you have 20%-22% equity now, you should be able to get mortg insurance removed if you did not go FHA.
that can help a bit. $500 off for a rental ?
Rents are decent in the area, are you dealing with Mello Roos ?
Most info on Zillow is worth what you are paying for it.
I don’t believe that Temec will increase much in the next year, a lot depends on interest rates.
