Getting a loan soon, anxious about it

Next month I'll (26M) be taking a personal loan of 10L to pay off my family's borrowings.

1. Any tips on managing the loan?
2. I have a good credit score so I can get it through a national bank like HDFC, SBI, etc.
3. Shall I pay it off in one instant in future or keep paying EMIs? I say one time payment because we plan to sell some property in future to get liquidity.
4. Anything else I should take care of?

I have savings of around 5L and I have a stable job for next 6-12 months (it's a startup so things are lil shaky right now). I plan to find freelance projects and increase my income. But this is the first time I will be taking a formal loan so it seems like a big and long commitment.

Thanks!
