Earlier quoted context omitted.
A few notes: Deductability of interest (and property tax) is a lot smaller than it was before with the new tax code. On a $1M house for a married couple, you might get ~$9k back but (in CA) that's offset by the $12k (EDIT: likely non-deductable due to SALT max) property tax. Anyway, using my own calculator ( https://medium.com/@usaar33/an-up-to-date-buy-or-rent-calcul... with other defaults), the situation you descri…
Property tax is deductible up to $10k.
Living in CA with near 10% marginal state income tax above $100k means that if you're buying a $1M home you're probably hitting the 10k without property tax.
