Here are some tough questions for you that if you can answer will get you more informed solutions and just maybe a little sympathy. You really need to talk to CPA/lawyer because it seems to all you have learned is that you must have tax deductions without thinking about property taxes, Mello-Roos, Home owners fees, maintenance, etc. What tax bracket are you in and do you have a simple tax return with just salary? What are your major expenses – car payments, etc?
You stated that you wanted good school district for your child and automatically bought property. Did you think about renting a 2 bedroom place for 2 years and then decide what to do? You moved here from a lower cost city and you wanted to keep you standard of living the same, right? Or were you scared by the prices just going up and thought that if you don’t buy now, that you will never own a place. Good luck.
