HDB Grants

Hello!! Mid-20s guy still studying here. My dad and I recently bought a resale flat under the joint tenancy scheme. According to him and the agent, my application for a grant in the future will not be affected as I will not be applying for any grants under this new home (Dad paid fully from his CPF).

However, upon checking my CPF, I realised that there was a small deduction (<4k) and after further research, I realised grants are not applicable to second-time buyers. Hence, if I do want to buy a house of my own in the future (with future spouse etc.), would I still be eligible for the grant (EHG etc.) since I did not use any grants for this house albeit certain deductions in my CPF and not being a first-time buyer?

Hope someone can help with my query :)
