Let's say you have 100k in your house as equity. S&P 500 pretty much guarantees a 10% reasonably safe return. Interest Rates are at 2% to 3% on a home loan.
It can't be that simple. I know I am missing something here.
As we've seen it's not simple, S&P is DOWN 25% YTD, and I suspect there's more downside coming. It does average 7-8% over the long haul, but bad timing has bankrupted many who jumped in at wrong time.
