$7,000 is on the low side for a strata loan. Lannock will lend it to you, but as a very rough rule of thumb, a strata loan makes economic sense when the special levy would be about $1-2,000 per lot for a large property and $5,000 per lot for a smaller property such as yours.
The suggestion about instalment payments might be suitable in your case, it depends what owners can afford and how urgent the works are.
To help OCs through the virus, Lannock has a Levy Assist loan that could help. We have waived all fees, including the establishment fee so that would resolve one of your problems.
We’ve also created a special Strata Premium Funding loan which also has no fees. We have pre-approved every OC in mainland Australia for this SPF loan.
Best to ask your strata manager about the legal requirements, as this isn’t really the place for legal advice. But, very generally speaking, you’ll need to hold a general meeting.
