I've been following this forum for quite a while and I tried googling for posts of those in a similar situation as mine but can't find much, so I decided to post my questions here. All help is greatly appreciated

I'm 35, single, Malaysian Chinese. Been here since 2005 and graduated with a bachelor's from NUS. Was a salaried worker from 2009-2019 and in mid 2019 I decided to take the plunge to start my own illustration and video production business (self-proprietorship). Just a few questions I have if anyone's applied for SC as a self-employed person:
- Do you need to provide the P&L statement or balance sheet or both?
- It says 'additional information may be requested' on top of the above. What sort of additional info would they request?
- It says the business documents must be for the latest 3 years. Since my business is only 1.5 years old, and well, I earned only slightly more than 30k annually last year, might this negatively affect my chances?
- This is just a word-of-mouth thing I heard: if you have been invited in the past by the SG Gov for a citizenship and if you don't respond, then your application for it in the future will be rejected. Is this true? I received an invitation 10 years ago but didn't respond as I was so young and green at that time.
- Through financial help from my parents I purchased acondominium in my name. Would it be wise to declare it in the application? (I heard that this may increase chances). However my concern is that with my not-so-great income it may raise eyebrows (though if asked I'll of course show the bank transfers).
Thanks a bunch once again!
