I think the data cancer does warrant study, on a large scale, not anecdotally. But I hate to break it to anyone that thinks the GSE policies aren't already responsible for exerting significant influence on market prices throughout the country. GSEs provide so much liquidity to the housing market that if they went away tomorrow interest rates would increase and prices would collapse due to reduced demand. LLPAs, loan limits, cost and access to credit, underwriting guidelines, affordability products, lending stability and liquidity during downturns (such as Covid), the 30 year mortgage (see Canada)…. All of this stuff impacts housing demand, and so what if any impact appraisal waivers have on housing prices is a drop in the bucket compared to these other factors. This is not an endorsement of the above, but it is the reality.
