i concur with you that many want everything, yet aren't willing to sacrifice anything.
but my comments was purely based on numbers on being house poor ...
lets say a working professional earning $55-60K is probably in their early-mid 30s and saved the 25% down payment.
if they were to buy an average 600sf condo (which I think would be reasonable size to expect for this person) at $650 psf, that would cost $390K.
with the 25% dp, the mortgage would be $292.5K ... let's round off to $300K because of incidentals like LTT, etc.
$300K @ 4.5% 5-yr term /25-yr amortization results in monthly mortgage = $1,660;
monthly condo fees for 600 sf = $300;
monthly property taxes = $260;
property insurance = $75
==========================
gross monthly costs excluding utilities (ie. phone, hydro, cable, etc) = $2,295
if they earn $60K pa, then monthly gross income = $5,000
$2,295 = 45.9% of the gross income, without considering those extra costs ... to me, that's house poor
$5,000
