This reminds me when auto mfgs started promoting 96 month (8 years) car financing deals to saddle more people who couldn't afford cars on standard 5 year notes since everyone shops on a monthly payment. The result of this was the ballooning of auto loans and people now rolling in negative equity into their new car purchases.
This post covid Pre Con financing "incentive" is the 96 months financing equivalent of real estate, it's crap being pedaled (at inflated cost per sq. ft.) to those who don't know any better or can't afford anything else. Realtors owe it to their clients to at least be transparent about it and not act like a Kia sales manager.
