How long does settlement take for a commercial property?
The timeframes for commercial contracts are generally longer due to the level of scrutiny required. It is common for commercial buyers to need in excess of 30 days when obtaining finance and conducting due diligence. Settlements of 60 to 90 days are also common in the commercial sector, while development sites can take up to 18 months to settle. Kollosche Commercial remains in regular contact with sellers throughout the sales process.
Should I use a commercial or residential agent?
Certain properties fall within the category of both residential and commercial in terms of what the potential end uses might be. Kollosche Commercial works in close collaboration with our residential sales agents. We can advise on the best strategy to market your property to its full potential and engage the right agents to execute an effective campaign.

Does Kollosche Commercial assist with due diligence?
Kollosche Commercial provides an end-to-end service for both buyers and sellers. With a qualified valuer on the team, buyers can proceed with peace of mind knowing they are receiving full transparency on the building they are purchasing along with accurate rental assessments in line with current market values.
What happens after my offer is accepted?
A Letter of Offer form will be provided by the selling agent to the potential buyer to complete when they are ready to make an offer. This form presents the buyer with the chance to outline their full offer including purchase price, initial deposit, special conditions and settlement period.
The vendor may alter the Letter of Offer and send it back to the buyer for review. This negotiation process can go back and forth until both parties are satisfied. Once the final offer has been signed by both parties, it becomes a legally binding document.
If the contract entered into is conditional on finance, building and pest or any other special condition, a time frame will be prescribed in the contract to meet the requirements of the conditions (often 14 days, but this can sometimes be longer or shorter).
It is the buyer’s responsibility to carry out their due diligence, book in a building and pest inspection, and liaise with their financer. If the buyer is satisfied with the outcome of any conditions outlined in the contract, the buyer’s solicitor will need to notify the seller’s solicitor that the contract can become unconditional.
Once a contract is unconditional, the balance deposit outlined in the contract will become payable and final searches will be conducted by the buyer’s conveyancer to make necessary arrangements for settlement. The bank will liaise directly with the conveyancer to arrange the transfer of funds on settlement day.
It is recommended for buyers to conduct a pre-settlement inspection on the morning that settlement is due to ensure the property is empty and in the same condition as when it was initially inspected. If there are any issues, it is important to mention this prior to settlement.
Kollosche Commercial facilitates this process with frequent communication between both buyer and seller to ensure a smooth transaction for all parties.
