the mello roos for one of these is $6000/year. I know officially you are not suppose to deduct it, but name me one person that actually ask his accountant to take the mello roos portion out of the itemized deduction.
therefore, we’re looking at $4000/year, or $330, that’s basically $50,000 extra in mortgage payment.
$600k for a 3300 sqft home in 4S ranch is very reasonable. plus the $50k reduction due to the mello roos, I say something in the low to mid $500k would be fair.
