We have been down this rabbit hole, basically the answer is no, everybody needs to be levied in the same manner.
One strata loan company has offered a hybrid product that does allow people to pre-pay but it causes personal tax issues and the ATO has rained down hard on them so I don’t believe they are still offering the product.
We took an approach of giving the owners 2 choices at the EGM, fully fund the capital needed in one levy, or agree to a strata loan of the same size over several years.
At the end of the day the latter was agreed over a 3 year term as the majority of owners felt it was better to pay a little interest and know the funds were available as needed.
The levies ramp up as work gets completed so it’s not like you pay the full amount from day 1. In our case we actually collected more than what was needed for the first quarters repayments so we were able to make an additional $150k repayment which saved interest and will reduce the term.
