One owner, one plan
Most firms touch one piece of your real estate. We connect them.
The purchase decides the tax outcome. The tax outcome funds the next purchase. The operations decide whether any of it is worth owning. Working with one team across all three is the point.

Buy the right property
Underwritten on real rental economics and, where it matters, the local short-term rental rules — before you write an offer.
- [02]Cost Segregation →
Keep more of what it earns
A cost segregation study pulls depreciation forward, so the first years of ownership come with much larger deductions.

Run it like a business
Launch it right, then operate it with systems — direct bookings, pricing, guest comms, maintenance — or hand it to us.

We own what we advise on.
Realm runs Prima, its own five-star short-term rental in Sonoma, and is launching Heavenly Pines in Tahoe with a client. The advice on this site is the advice we take with our own money.
Cost segregation studies are engineered by our partner, Veritax Advisors. Everything else is us.
