Profitable on paper, but still writing big checks to the IRS?
You did everything right. You found the property, took the risk, and put in the work. The one thing nobody told you: a large slice of what you paid can be deducted far sooner than 27.5 or 39 years.
The components inside and around your building - flooring, cabinetry, fixtures, wiring, landscaping, site work - can often be written off in the first year. That is typically 20-40% of your property's cost sitting frozen on a decades-long schedule, when it could be cash back in your pocket now.
Every year you wait is another year that deduction stays locked, and another check to the IRS you may not have owed.
Average first-year deduction
That is Seneca's average first-year deduction on qualified properties. With 100% bonus depreciation back for 2026, qualifying components can often be written off entirely in year one. The free guide shows you whether yours is one of them.

The strategy advisors recommend to serious investors
"I've referred multiple clients to Seneca, and each time they uncovered significant tax savings. They've become a trusted extension of our tax strategy."
"My accountant recommended Seneca. They identified over $450,000 in assets that could be reclassified for faster depreciation, and their engineering team was thorough." - David W., multifamily owner
"Every client we send their way is treated like their most important client. Their attention to detail and genuine commitment to value set them apart."
The questions investors ask first
Yes. It is an IRS-recognized way to accelerate depreciation. The IRS even publishes its own Cost Segregation Audit Technique Guide describing how a proper engineering-based study should be done, and Seneca's studies are built to that standard.
A properly documented, engineering-based study does not raise audit risk on its own. Seneca also backs every study with AuditDefense: if a study causes a depreciation adjustment of more than 5% in an audit, you get 100% of the study fee back.
Most income-producing property qualifies, including short-term rentals, long-term rentals, multifamily, and commercial buildings, and it tends to pencil best above roughly $500,000 in basis. The guide includes a checklist so you can self-assess in minutes.
Pricing depends on property type and size, and a free savings estimate shows your projected first-year deduction before you commit to anything. Seneca's average first-year deduction on qualified properties is $171,243.
Accelerated depreciation can be recaptured when you sell, so cost segregation works best if you plan to hold for several years. The guide explains recapture in plain English so you can decide if it fits your timeline.
Most engineering-based studies are completed in 2 to 4 weeks, and Seneca works in all 50 states either remotely or with an on-site visit.
