Three ways to sell

Owners who want to sell a property can basically choose between three kinds of support. A traditional broker markets the property as it is. An integrated partner combines marketing with development, planning, financing or asset management. A pure adviser analyses the market and options but leaves implementation to others.

Which route fits depends less on the size of the property than on whether its value is already visible today or must first be explained and created.

When development potential sets the price

With some properties, investors are not buying the building but a perspective. Typical cases are larger sites, older apartment buildings in need of renovation or plots with unused building reserves. Here the quality of the groundwork determines the price more than the reach of the listings.

  • Zoning rules allow more floor area than has been built, for example through adding storeys or replacement construction.
  • A change of use, say from commercial to residential, is conceivable but has not yet been clarified.
  • Renovation needs are high, and buyers must be able to assess costs and phasing.
  • Financing or structuring, such as selling in stages or selling with a building permit, directly affects the achievable price.

In such cases, a partner with development expertise can prepare feasibility studies, massing studies or cost estimates and turn them into a coherent sales story. Buyers then reach a robust assessment faster, because not every party has to reinterpret the property from scratch.

The more a property is valued beyond its current state, the more thorough groundwork pays off.

When a lean sale is enough

A detached house in good condition or a condominium in a liquid market usually needs no development strategy. What counts is realistic pricing, good documents, professional presentation and a well-run bidding or negotiation process.

An example: a community of heirs sells a well-kept condominium in a cantonal capital. Comparable units change hands regularly, the price range is known and demand is broad. Here a sound valuation, good photos, complete documents and a clearly managed sales process achieve more than a feasibility study. It would be different if the same heirs owned an old two-family house on a large plot with reserves.

Buying an entire value chain in this situation may mean paying for services that do not increase the proceeds. The central question is therefore always: can the additional focus on development and financing actually affect the transaction value, and by how much?

How to vet a partner

  • References: comparable properties, regions and deal sizes, ideally with contact persons.
  • Fee model: commission, flat fee, hourly rate or success fee, and who bears the cost of studies if the sale falls through.
  • Conflicts of interest: does the partner, directly or through affiliates, act as buyer, investor or general contractor?
  • Exclusivity: duration, termination options and what applies once it expires.
  • Transparency: do you receive all offers and feedback from interested parties?
  • Contract: which services are owed, and when is a fee earned?

Have conflicts disclosed

Integrated providers are often also active as investors or developers. That is not a problem in itself but should be disclosed in writing and addressed in the mandate agreement. Have larger contracts reviewed by an independent professional.

Preparation that always pays off

Whichever partner you choose, good documentation strengthens your negotiating position. Buyers and banks now expect complete records, often in a digital data room.

  1. Current land register extract with easements and annotations.
  2. Plans, floor area schedule and building insurance certificate.
  3. Rent roll, leases and service charge statements.
  4. Condition assessment with investment plan.
  5. Planning law checks: zoning plan, building regulations, any special development plans.
  6. Check of the register of contaminated sites.
  7. Tax and financing issues: property gains tax, any early repayment penalty on the mortgage.

Property gains tax and transfer charges are governed by cantonal law and can significantly affect net proceeds. Clarify these points early with a tax adviser.

Frequently asked questions

Which properties benefit most from an integrated approach?
Mainly larger sites, older apartment buildings and plots with unused reserves, where value depends on future use.
Is a development partner always the better choice?
No. For standard properties in liquid markets, a lean marketing process is usually enough. Additional services are only worthwhile if they raise the proceeds or the certainty of the transaction.
Should I obtain a building permit myself before selling?
It can raise the price but ties up time and money and carries the risk of objections. Whether it pays depends on the property, the market and your appetite for risk.
What role does financing play in a sale?
In larger transactions, whether buyers can finance the deal can determine the price. Thinking about financing early makes the offer accessible to more interested parties.
How long does a sale with development groundwork take?
Considerably longer than a standard sale, because studies and checks come first. Depending on complexity, plan for several additional months and set milestones in the contract.
