About DepreciMax — For informational purposes only. Not tax advice.

The first platform built to calculate bonus depreciation accurately before you close

We combine real estate market data with AI-powered photo analysis to estimate bonus depreciation potential on short-term rental properties — so investors can make smarter acquisition decisions upfront.

"Most cost segregation studies happen after closing. By then, the decision is already made. We built DepreciMax to move that insight upstream — so investors know their tax position before they sign."

The first of its kind: data + AI imaging for bonus dep

Traditional cost seg studies cost $5,000–$8,000 and happen after closing. DepreciMax is the first platform to use a combination of real estate data signals and AI analysis of listing photos to produce an engineered-quality bonus depreciation estimate before you make an offer — at a fraction of the cost.

What makes us different

Built for the decision, not the filing

🤖

AI Photo Analysis

Upload 7–9 listing photos. Our AI identifies finishes, fixtures, and improvements — then classifies each as 5-year, 15-year, or 39-year property under bonus depreciation.

📊

Market Data Scoring

Every property gets a Bonus Dep Score based on age, land value ratio, price per square foot, and property type — before you even look at photos.

⏱️

Before Closing, Not After

Traditional cost seg studies happen post-close. DepreciMax gives you the intelligence during your search — so the tax outcome informs the offer, not the other way around.

💰

A Fraction of the Cost

Cost seg studies run $5k–$8k. Our AI property report is $99 and available in minutes — engineered-quality estimates without the engineering firm invoice.

Why now

100% bonus depreciation is permanent — and most investors still don't use it correctly

The One Big Beautiful Bill Act (OBBBA), signed in early 2025, permanently restored 100% first-year bonus depreciation for qualifying property placed in service after January 19, 2025. Unlike the TCJA's provision — which had been phasing down since 2023 — this has no scheduled sunset. The deduction is here to stay.

The opportunity isn't in finding the provision. It's in finding the right properties. Not every STR produces the same bonus dep outcome. Land value ratios, property age, finish quality, and outdoor amenities all determine how much of your purchase price is bonus-eligible — and those signals are readable before you close.

We built DepreciMax to make that analysis fast, affordable, and available to every investor — not just the ones who can afford a $6,000 engineering study on every deal they're considering.
