We were renting a 3 bedroom apartment for $1,800 a month. After working from home a bunch, I had banked $30,000 in cash and put down 7.7% on a $390,000 house.
Our mortgage went up $200 a month over rent, so $2,000 a month. 3.25% fixed, 30 years.
Our old apartment? 20 months later? $2,300 a month.
That $2,000 a month can also raise if you've included property taxes and insurance in the payment. If you're not including property taxes and insurance then you're not really doing a full comparison.
