First letting of a new build: letting off-plan – with no vacancies at move-in

Anyone building a new property wants it fully let at move-in. That only works with a first letting that starts months before completion. Timeline, documents, rent calculation and the typical mistakes.

An apartment building with eight flats that stands empty for three months at move-in quickly costs the developer CHF 40,000 in lost rent – on top of the ongoing mortgage interest. The first letting is therefore not an appendix to the building project, but part of the planning.

In brief

  • Start of marketing: 4 to 6 months before move-in
  • Visualisations, floor plans and building specification replace the photos
  • Calculate the rent based on investment costs and comparative rents
  • Contracts with an “expected” move-in date and a clause for delays
  • ImmoBilà fee: one month’s rent per flat let – only on success

The timeline

  • 6 months before move-in: rent calculation, marketing documents, prepare website/listings
  • 4–5 months before move-in: listings live, first viewings on the construction site with helmet
  • 3 months before move-in: bear in mind prospective tenants’ notice periods – anyone giving notice now can move in on time
  • 1–2 months before move-in: contracts signed, targeted advertising of remaining flats
  • Move-in: handovers with report, defect list to the site management

Documents for off-plan marketing

  • 3D visualisations of façade and interiors
  • Scale floor plans with floor areas per flat
  • Building specification: kitchen, bathroom, flooring, heating, ventilation, washer-dryer tower, parking spaces
  • Site plan, surroundings, public transport links, schools, shopping
  • Draft rent roll with net rent, service charge advance, parking rents

Rent calculation in a new build

In a new build there are no previous rents – the rent is derived from the investment costs: land value, construction costs, ancillary costs, capitalised at the permissible net yield (reference rate + 2 %) plus operating costs and reserves. The second check is comparative rents for new-build flats in the municipality. Anyone starting too high ends up not letting the least attractive flats at all; anyone starting too low is tied in for years.

Experience Baselbiet 2026

New-build 3.5-room flats in Liestal, Pratteln or Füllinsdorf are currently offered at between around CHF 1,900 and 2,400 net, 4.5-room flats between CHF 2,300 and 3,000 – depending on location, fittings and outdoor space. We assess the specific location.

Marketing and viewings

  • Listings on Homegate, ImmoScout24 and other portals – with visualisations and floor plans
  • Project page with all flats and availability
  • Viewings on the construction site: in groups, with safety equipment, in consultation with the site management
  • Show flat as soon as one unit is finished – significantly increases the closing rate
  • Credit check as with any letting: debt enforcement extract, proof of salary, references, liability insurance

Tenancy agreements before completion

The tenancy agreement is signed before completion. Important: state the move-in date as “expected” and agree a clause for construction delays (postponement of the start of the tenancy without compensation up to a defined deadline). Deposit at most three months’ rent in a blocked account. Service charges on account – in the first year there are no empirical values, so calculate cautiously and adjust after the first year.

Typical mistakes

  • Starting too late – prospective tenants have three-month notice periods
  • Only floor plans, no visualisations – laypeople cannot read plans
  • All flats at the same price per square metre – penthouse and ground floor differ by 20 % and more
  • No clause for construction delays – tenants who have given notice on their flat claim compensation
  • Management and accounting not arranged – from move-in, service charges and reminders start running

What does the first letting cost?

One month’s rent per flat let – due only once the contract is signed.

Do you also take over the management afterwards?

We concentrate on letting.
