Post-2017 TCJA the standard deduction usually beats itemising. The MID toggle shows exactly when it earns its keep and when it's just folklore.

Renting plus investing wins clearly. Combination of high invest return, modest appreciation, and short-to-medium horizon. MID is unlikely to flip this.
Post-2017 TCJA, MID only helps if itemised deductions (mortgage interest capped at first $750k loan + $10k SALT) exceed the standard deduction. For most middle-income buyers the standard deduction wins; for high-income coastal buyers MID can still meaningfully help. Set the toggle to model both.

When mortgage interest + capped SALT exceeds the standard deduction ($29,200 MFJ / $14,600 single in 2025). For a $400k mortgage at 7%, year-1 interest is around $28k, combined with $10k SALT that's $38k, comfortably above the MFJ standard deduction. For smaller loans or lower rates, MID often doesn't beat the standard deduction at all.
State and Local Tax deductions are capped at $10,000 (TCJA). High-tax states (CA, NY, NJ) have $20k+ in SALT for many homeowners but only $10k counts. That's the main reason MID benefits don't scale linearly with property value in expensive states.
No, AMT was largely defanged by TCJA (high exemption + phase-out). Very few households trigger AMT post-2018. If your scenario does (extraordinary state taxes plus large ISO exercises), the MID benefit shown is overstated.
