Selling a residential portfolio of 30 apartment buildings

Selling a residential portfolio of nearly 30 apartment buildings rarely fails because of the market – but frequently because of the data. Leases in ring binders, maintenance history in the property manager's head, service charge statements in changing formats: what has grown over decades will not survive a buyer's due diligence. A private investor in central Germany therefore approached the sale from the data up, and brought in external support to do it.

Starting position

The owner had built the portfolio over a long period. The assets were managed and let, and the owner knew the commercial fundamentals well – but none of it was documented in a form a professional buyer could work with.

For a sale of this size that is a tangible risk. Buyers who hit gaps during due diligence routinely respond with price reductions or withdrawal – not because the assets are poor, but because the risk cannot be assessed.

The brief

The mandate covered the whole sale process – from creating a reliable data set through to the notary appointment:

• Structured capture of all asset-relevant data: location, year of construction, floor plans, leases, maintenance history, service charge statements
• Digitising and systematising the documents in a structured data room
• Valuing each asset using the income approach, including passing versus market rents, vacancy, WAULT and capex requirements
• Deriving a market-based price range from comparable transactions and local submarket benchmarks
• Developing the marketing strategy and defining the target buyer groups
• Preparing the teaser, information memorandum and data room structure
• Running the bidding process through to exclusive negotiations

Getting a residential portfolio ready for market

Data before marketing

The most demanding part came before the first buyer contact. For every asset, leases were recorded, passing rents set against market rents, vacancies documented and the maintenance position captured systematically. Whatever was missing was obtained – not during due diligence, but ahead of it.

Valuation as the basis for argument

Valuing each asset individually served more than price setting. It produced a traceable derivation for every property: which rent is sustainable, what capex is due in the short to medium term, how does the asset sit in its local submarket? That derivation withstands negotiating pressure; a headline figure does not.

Off-market rather than broad marketing

For a portfolio of this profile, wide marketing is rarely the best route. The target group was defined as regional portfolio holders, family offices and smaller institutional investors – buyers who know the submarket and do not need a national story. The process ran accordingly as a structured off-market approach with selective outreach.

A bidding process with clear timing

Indicative offers were assessed and compared – not only on price, but on transaction certainty: financing confirmation, acquisition profile, experience with comparable portfolios. Exclusive negotiations were conducted with the bidder who offered both.

Outcome

The portfolio was sold to a regional portfolio holder through a structured off-market process. Establishing a reliable data set early and positioning the portfolio clearly noticeably shortened the marketing period and supported a market-level price.

What sellers take from this

• Data preparation is not a formality. It is the single lever with the greatest influence on the achievable price.
• The target buyer group determines the process. A regional residential portfolio does not need a broad process, it needs the right ten addresses.
• Transaction certainty belongs in the offer assessment. The highest bid is only the best one if it also reaches closing.

The profile this mandate requires

What was needed was someone who commands both: the craft of valuing residential property using the income approach, and the ability to run a sale process with institutional counterparts. Plus a willingness to work through decades of accumulated paperwork – a part of the job many underestimate and which materially shapes the result.
