Your property.
Your decision.
A clear foundation.

Selling an apartment building deserves careful thought. You need more than a number: an understandable assessment, clearly identified assumptions and a path you choose yourself.

TRUST STARTS WITH CLARITY

What is documented?
What remains open?
What does it mean for you?

01

Understandable.

You should be able to follow how an assessment is reached and which information is still missing.

02

Agreed.

Services, remuneration and the marketing approach should be clear before you appoint an agent.

03

Your choice.

You decide whether, when and on what terms to take the next step.

01 / UNDERSTANDING VALUE

A sound figure.
Sound reasons.

A district average cannot explain an individual building. An assessment becomes meaningful when income, tenancies, condition and the precise location are considered together.

The foundations of your building’s assessment
FoundationWhat should be reviewedWhat remains subject to verification
Income & tenanciesRent roll, tenancy agreements, vacancies, arrears and ongoing expenditure.Unverified information and future rents are not established income.
Building & investmentFloor-area records, building condition, energy certificate and identifiable works.A viewing cannot replace a detailed technical inspection or a firm renovation budget.
Location & marketThe exact address, comparability of market evidence and valuation date.Asking prices are not proven sale prices; a district average is not a property value.
Potential & scenariosAvailable records on use, planning and possible alterations.Attic development, conversion or higher income require their own assessment.

The assessment must suit its purpose. An agent’s market-price assessment is not a formal expert valuation report. Legal, tax and technical questions require the appropriate specialists.

02 / SHAPING THE SALE

A clear path.
Your approval.

A sale begins with your objectives. Ideal Real’s responsibilities are defined for your particular appointment. These questions help structure the conversation.

Explore the sale process
  1. 01

    Objectives & starting point

    What should the sale achieve for you? Timing, ownership, available documents and unresolved questions are the starting point.

  2. 02

    Price & positioning

    What price expectations can be substantiated? Which buyers may be suitable? Discreet introductions and public marketing should be considered deliberately.

  3. 03

    Offers & negotiation

    How credible are the interest, financing and terms? The complete offer matters, not just the highest figure.

  4. 04

    Decision & completion

    Which conditions remain to be resolved? You decide whether to accept an offer. Contract preparation and completion involve the relevant qualified professionals.

03 / BEFORE APPOINTMENT

Clarity before
you sign.

A well-defined appointment leaves less room for misunderstanding. Record the essential terms in writing with Ideal Real.

01

Scope of services

Which assessment, document preparation, marketing and support are included? What requires a separate appointment?

02

Remuneration & costs

How is commission calculated, when is it payable and what other costs may arise? VAT and additional services also belong in the agreement.

03

Appointment & communication

What duration, exclusivity and termination arrangements apply? How are approvals, updates and any activity for both parties addressed?

Your specific terms follow from your agreement and the applicable law. An enquiry through this website does not itself create a paid brokerage appointment. This website does not guarantee a sale price or completion date.

04 / PERSONAL ACCOUNTABILITY

05 / BEING OPEN ABOUT INFORMATION

Transparency
includes the details.

What do the district pages and photographs represent?

The 23 district profiles explore local issues for owners. They do not represent 23 branch offices. Architectural photographs illustrate Vienna apartment buildings; unless expressly identified, they are neither current listings nor completed-sale references. A photograph alone does not demonstrate a successful transaction.

How do you stay in control of your data?

A description of your enquiry is sufficient to begin the conversation. Before sharing extensive documentation, establish which data is needed and how it should be sent. Optional external forms on this website load only after permission is given. Your selection can be changed through Cookie settings in the footer. The privacy notice explains the details.

Where can you find withdrawal information?

The “Withdraw from a contract” page explains the context and provides a form assistant. It prepares a declaration; it does not automatically send a withdrawal notice. Whether a right of withdrawal exists and which deadline applies depend on the particular contract and legal requirements.

Is a statement unclear or potentially incorrect?

Please tell us. Identify the page, the statement and, where possible, a source. Professional explanations should remain open to scrutiny. For your own building, the review of current documents is what matters.
