Would you like to place a wager? I bet that the median home price in tech-centric metro areas (seattle, sf/bay, la, nyc) will decline by 10% or more in July 2023 versus July 2022.
For many in tech metros their homes could decrease in value by 25% or more from their current values and the home would still be worth more than they paid for.
In any case they won’t want to sell for a mortgage that effectively costs the same over a 30 year loan with a higher interest rate.
They are not valued on a binary positive or negative cashfows. They are valued at NPV of future cashflows. You can justify a high burn rate with the expectation of earnings in the distant future. But as inflation/rfr goes up then then investors value money today more and more and money in the future less and less.
