A private advisory service for homeowners preparing to sell high-value covering London, the Home Counties & Cotswolds property — focused on maximising value before going to market.

In the upper tier of the London market, value is shaped long before a property is formally introduced. Presentation, positioning, timing, and representation all influence the outcome — often more than the property itself.

This advisory ensures those elements are considered carefully, and aligned from the outset.

What this service is
A tailored, confidential service designed to prepare your property for a successful sale.

We work with you prior to listing, providing independent guidance on how your property should be presented, positioned, and brought to market.

The objective is simple:
to achieve the strongest possible result when you sell.

What this achieves
Stronger first impression with buyers
Increased perceived value
More effective and targeted marketing
Reduced time on market
Greater likelihood of achieving full asking price

What the advisory includes
Each engagement is tailored, but typically includes:

Property assessment
A detailed review of how your property will be perceived in the current market.

Presentation strategy
Clear guidance on adjustments that materially improve value — from layout to detailing. We can style and edit your interiors to maximise presentation. Interior styling is hugely beneficial to all properties coming to sales or lettings market.

Positioning & timing
Advice on when and how to introduce the property to the market for maximum impact.

Agent selection & strategy
Independent guidance on choosing the right agent and approach.

Pre-market preparation

Who this is for

This service is suited to homeowners who:

own high-value or design-led property
want to maximise value before going to market
prefer a discreet, considered approach

How the advisory works
Initial consultations are offered on a complimentary and confidential basis.

Where appropriate, we continue with a tailored advisory engagement, aligned to the property and the intended sale.

In some cases, we may introduce trusted agents and receive a referral fee. This is always handled transparently and does not affect the independence of our advice.

A discreet and personal service
All advisory is handled privately and with complete discretion.

Engagements are limited to ensure each property receives the level of attention required.

"Amazing experience! I contacted Natalie to re-stage my house, which had been on the market for two years without selling. After her intervention, we purchased £10,000 worth of furniture at 75% off, thanks to her excellent contacts. Shortly afterwards, we successfully sold the property at the full asking price of £3.75 million. We’ve been absolutely delighted with the results of her Private Advisory work, a testament to the Private Property Advisory standard."
