You are right AN, the multipler goes up with the sfr’s and the sq feet. A 2k rent sfr up here is 300-350k right now, it was 260-300k a year ago. So it was 150x and below, now it’s crept above that, but it’s still close. Big sfr’s aren’t good rentals, I just use the numbers for comparisons to value.
The example I used dropped from 400k to 150k, so 55-70% from peak isn’t impossible, it happened. It may not happen in your town, it may not happen again, but it happened.
