Good analysis, Dave! And it's nice to see you admit the mistakes. Anyone that claims to know the future is a fool.
I'm not a data guy, but I had the same expectations as you. Growth in the first half, slowing in the second. I'm still holding to my belief that 2023 will be the correction. I don't anticipate a 2008 crash, but it would not surprise me to see us lose most of the gains from 2021/2022. I'm also predicting some major turns in short-term rentals. Markets are becoming saturated, too many amateurs jumped on the band wagon with no experience based on misleading numbers, and the prices are so high that a hotel makes more sense to many travelers.
As prices drop, seller stress and motivation rises, more vacant houses listed (they where forced to move on), the more creative offers will be attractive. Just yesterday I have an appointment to meet and maybe sign a contract to buy subject to, give the seller their equity, a nasty divorce, a 1.5 yr old mortgage at 3% and could be $500 cash flow that was caused by a halt in the market and the seller being sick of agents. He was ok with me taking over his mortgage payments. This possible deal would NOT have been very likely 1 yr ago. He would have sold on the MLS.
Love the fact you did a retrospective on your predictions, you don’t see that very often. Agree that the point of predictions is to build a model. In software development, the purpose of a retrospective is to improve (processes, models, systems…). What will you take from this analysis to improve future predictions/modelling?
