How much should someone be making/spending to afford a house in Toronto, in your opinion?
If you are talking a detached house, I would think in the ballpark of:
$951,000(average detached house price)*.8(loan amount w 20% downpayment)=761,000
Servicing loan is approximately $500 per $100,000 per month so monthly payment is ~$3800.
This payment should be ~25% of net income, so net income needs to be $15000 per month.
Therefore gross income needs to be ~$20000/month or $240,000 per year
This should be close to correct but it can be pushed around a bit (especially downpayment and % of net income). Best case (20% down and 30% ratio) is $150,000 per year. Worst case (5% down and 25% ratio) is $280,000. Buying a detached house in Toronto without a substantial downpayment (ie. hundreds of thousands of dollars) is beyond the reach of most.
Obviously many people bought houses long ago when the math wasn't so painful, so they can afford to hang out in the house they have on much lower income. Alternatively, give up on the idea of detached and the situation improves (although to comfortably make a real go of it, household income needs to be $75,000+, preferably $100,000+).
