Negative Leverage — IRR / Tax Play Cap Rate: 1.0%  |  30yr Rate: 6.8%
Leverage reduces cash returns at current rates.

The current 30-yr mortgage rate (6.8%) exceeds the estimated cap rate (1.0%). Financing reduces your cash-on-cash return below the cap rate. Markets like this may still make sense as IRR plays — factoring in appreciation, depreciation, and a future refinance when rates drop.
