Who we are

About Stackly Advisory

We are a private residential advisory built around one idea: a house should be judged before it is priced. Our advisors read plans, survey streets and write the valuation memo themselves — then negotiate the purchase or sale they recommended.

Seventeen years, twelve markets, and a register capped at thirty-four residences a year so a partner can stay on your file from survey to closing.

Testimonials

What our clients say

“

They told us the house we loved was priced eight per cent ahead of its street, and to wait. Eleven weeks later we bought it at the number they had written down.

M. & J. Okafor
Coral Gables, FL

“

Our house never reached a public listing. Three private introductions, one offer above ask, and it closed before the neighbours knew it was available.

“

I asked for an investment view rather than a tour. What arrived was a nine-page memo with a recommendation I did not want and eventually agreed with.

How we build a valuation memo, line by line

What we do

Four mandates, not a menu

Each mandate is led by a partner and priced on a single fee, agreed before work begins.

Buying

A search built from your brief, including owners who have not listed. We open the conversation before a listing exists.

Selling

A staged release — private register first, open market second — with plans, photography and a price we can defend on the call.

Valuation

A written memo on what a residence is worth now, what it costs to hold, and what it should reasonably return.

Investment & stewardship

Counsel after closing: renovation review, tenancy, insurance and the timing of an eventual sale.

The process

Four steps from brief to keys

Brief. One conversation to set city, architecture, budget and timing — and what you would refuse outright.

Survey. We search the register, the private files and owners who have not listed, then shortlist honestly.

Memo. A written valuation on every shortlisted property, delivered before you walk it.

Negotiate and close. Your partner runs the negotiation and stays available long after the keys change hands.

Modern House Facade

Why Stackly

Why choose Stackly

The same four commitments sit behind every mandate we take, whether you are buying a first waterfront residence or releasing an estate quietly.

Valuation before viewing

Every engagement opens with a written memo, delivered before you walk the house.

One partner per file

The advisor who surveys the residence negotiates it and signs off the closing.

Resident in every market

Twelve markets, each covered by an advisor who lives in it.

A register kept short

Thirty-four residences a year, so a partner stays on your file from survey to closing.

Book a site visit

See the residence before you decide

Tell us which residence you would like to walk and when suits you. A partner confirms the appointment within one business day.

Accompanied by the advisor who holds the file.

The valuation memo arrives before the visit, not after.

Weekend viewings by appointment.

Questions

Common questions, answered plainly

If the answer below is not the one you were hoping for, it is still the honest one. Anything not covered here, ask us directly.

Something else on your mind?

Ask a partner directly. One business day, no call centre.

No. The first written memo on a shortlisted residence is part of the engagement, whether or not you go ahead.

On introduction, under a short confidentiality note. Seven residences are currently held that way across the twelve markets.

Occasionally, and only alongside a local co-advisor we already trust. Otherwise we refer you rather than guess.

One business day, from the partner who covers your market — not from a coordinator or a shared inbox.

A single percentage agreed before we start, with no marketing charge and nothing payable if the sale does not complete.
