"Renting is throwing money away"
So is the interest portion of a mortgage payment — roughly 70% of it in the early years — plus property taxes, insurance, and maintenance, which together rival rent in many markets. The honest frame is not rent vs nothing; it is rent vs the non-recoverable slice of ownership. Run the cost-compare calculator: the non-recoverable lines are closer than the slogan implies.
"Buying is always better long-term"
Long-term is doing heavy lifting. Transaction costs take years to amortize away; appreciation is local and cyclical (ask 2010 Phoenix); and the forced-savings benefit only accrues to people who stay. For a household that moves every three years, "long-term" never arrives — renting is not the compromise, it is the correct product.
"Prices only go up"
Nominal prices mostly do; real, inflation-adjusted prices have had flat decades and deep regional crashes. The comparison calculators here let you test pessimistic appreciation — a useful discipline, because a decision that only works at 5% growth is a gamble with a spreadsheet.
