Talked to another investor this week who bought a $600K rental last year, did zero tax planning, and left roughly $60K in deductions on the table because nobody told them about cost segregation before year-end.

Here's the thing most new investors don't realize: depreciation isn't automatic optimization. Straight-line depreciation on a rental gives you a flat deduction every year for 27.5 years. A cost segregation study reclassifies parts of that same property (appliances, flooring, fixtures, landscaping) into 5, 7, and 15-year buckets — which lets you front-load a huge chunk of that deduction into year one.

The catch: it only works if you (or your CPA) act on it before you file, and ideally the same year you buy or renovate. Most investors find out about it after the window has quietly closed.

If you bought or renovated a property this year and haven't asked your CPA about cost segregation yet, that's a phone call worth making before year-end — not in April.
