~20% or my housing "cost" is paid for by a tax break for owning a house. Another ~20% is principal.
When you also factor in that the Fed guarantees to devalue money at AT LEAST ~3% per year, and you have 5x leverage (or more) - that's another ~15% effectively subsidized by the government.
So when you have sufficient cash flow - it's easy to look at your housing "cost" as only ~40% of the actual payment.
Compared to rents, this is a steal.
