What we do

Four ways we work for you.

Private buying

We search on- and off-market, read every disclosure and permit file, and negotiate as if the money were ours. You see fewer homes and better ones.

Discreet selling

Pricing built on our own sales data, an editorial film and print campaign, and a private preview to qualified buyers before anything goes public.

Off-market access

Roughly four in ten of our transactions never reach the open market. Our buyer and seller lists are the reason, and you can join them.

Two-coast relocation

Sell in the Valley, buy in Miami, or the other way round, with one team running both sides on a single timeline.

Questions

What buyers and sellers ask us first.

Straight answers on private sales, relocating between California and Florida, taxes and fees.

Sellers who value privacy let us show their home to a short list of buyers we have already met and qualified. There are no photos online, no open houses and no days-on-market history. About four in ten of our sales close this way.

It is most of what we do. One advisor runs your sale in the Valley while a partner in Miami Beach runs your purchase, on a single timeline. We coordinate tax-residency timing, school transfers, movers and closing dates so you never own two homes longer than you mean to.

Florida has no personal state income tax, while California's top marginal rate is 13.3%. Changing domicile has rules and the timing matters, so we work alongside your CPA and counsel rather than in place of them. Property taxes in Florida are higher, which our cost calculator shows.

Seller fees are agreed up front and in writing, and they include photography, film, print and private previews. We never ask buyers for a retainer. If you sell with us in one market and buy in the other, we discount both sides.

Yes. Every residence can be toured live by video with your advisor, who walks the property at your pace and answers questions as you go. Many of our Miami buyers make their first offer after a video tour and a second, in-person visit.

Most of our clients do. We work with your attorneys on the purchasing entity, keep your name out of marketing and showing schedules, and use NDAs for any off-market viewing.
