One of my other questions was if as the loan is for investment can you claim the interest you pay like a loan for stocks
Sorry, I don't understand what you mean with the highlighted bit.
Anything you would do differently if you had your time again?
Being only 4 months into it, I think I didn't even have time to make a mistake yet D: . Seriously, not really so far. Sometimes I do see an ad for some loan with better conditions than mine and I'll wish I had been able to snatch the lower interest. But I think that's inevitable, and given the expectations of the operation, 3% vs 6% shouldn't make much of a difference.
