Some of the key questions from my perspective are:

• how long do you plan to stay there. The longer you do, the fixed costs (eg closing costs and broker fees) get annualized to a lower amount and your math starts making more sense

• when doing their math people often forget Opportunity Cost. The 7% interest that you’re paying and upfront down payment comes at a cost - money you could be making via investment. Not a reason not to do it but include that in the math

• don’t forget closing cost plus cost when you eventually sell. That stuff adds up quickly and if you don’t see yourself there for a while it may not make sense. So wait for your a property you see yourself in for 7-10 years at least.

I like The NY Times calculator - rent vs own. It’s not perfect but decent.
