The Plain-English Version

In one sentence: these are free tools that answer the four questions building owners actually ask, in about a minute each, before you ever talk to anyone.

Meet Ben. He bought a $700,000 fourplex last spring and has heard the phrase cost segregation three times without ever quite understanding it. He opens the calculator, picks apartment building, types $700,000, and sees an estimated first-year write-off somewhere between $110,000 and $250,000. That is the moment it clicks: this is real money, and it is his. He runs his work truck through the vehicle checker on the same visit. Then he clicks the free proposal, sends two documents, and 24 hours later has a written minimum for his exact building. No sales call. No jargon. Four tools, one evening.

Every number these tools produce is an estimate. The engineered study is the real number. The tools exist so you walk into that conversation already knowing what to expect.

What This Page Is

Every tool here answers one question an owner actually asks: what could my building write off, does my truck qualify, how do I prove my hours, and what is my real number. None of them replace an engineered study or your CPA. All of them get you to a better conversation with both, faster.

The Tools

Tool 1

The Cost Segregation Savings Calculator

Choose your property type, enter your purchase price, and let the calculator subtract the land value for your state and city before it estimates your first-year write-off. About a minute, and the number is honest. Most owners see 20% to 45% of building value in year one.

Tool 2

The 6,000-Pound Vehicle Deduction Checker

Three questions decide whether a truck or SUV qualifies for accelerated first-year depreciation: the weight rating on the door sticker, the business-use percentage, and the price. Answer them and see the potential year-one deduction.

CHECK MY VEHICLE →
Tool 3

ProofHours

Real Estate Professional Status and the short-term rental loophole are proven in hours, and the IRS asks for the log. ProofHours is tracking software that builds the contemporaneous record examiners respect, as the work happens, property by property.

Tool 4

The Free Proposal

The only tool on this page that produces a number you can rely on. Send us two documents, and within 24 hours you receive a written proposal with a minimum first-year write-off for your specific building, at no cost and no obligation. If a study does not make sense for your property, the proposal says so.

How the Tools Fit Together

The calculator estimates the pile. The proposal measures your pile. The study proves it, line by line, to the standard an IRS examiner expects. The vehicle checker and ProofHours handle the two questions that decide whether you can use the deductions once you have them: whether the truck qualifies, and whether your hours hold up. Use them in any order. They all point to the same place: a number you can defend.

The Bigger Play

Tools tell you what is possible. The Investor's Tax Playbook tells you what the wealthy actually do with it: nineteen plays, from the vehicle deduction to the step-up in basis, each one explained in plain English by the people who defend the numbers.
