I watched the first 3 minutes and realize the rest is a waste of time.
First – home prices are way higher than that, and most people don’t have 2-3 months of mortgage payments sitting idle in checking
Second – There’s nowhere I know of that you can gain more interest on savings than an 8% HELOC without risk
Third – to take out a HELOC you have to paid equity into it, so new buyers would have to wait years, and even longer in a deflatign market.
If there was a way to truly pay a mortgage off in 1/3 the time by revolving debt and savings it would be more prevalent than a video on youtube.
