Conventional one mean fix term-loan? If you are term loan, there are not benefit you settle early, and please check your contract, if you clear early may involved with penalty charge.

So if let said you ready want to settle early, then i will said lump sum (save until you able to fully settled) the payment. In between you can put the money at FD to earn interest)

Because not point you lump sum annually or monthly dump in extra but not benefit on saving the interest under term loan.
or you can refinance to semi-flexi / fully flexi loan.

May i ask how many % interest rate in your current loan? If it higher than 4% like 6%+-, better refinance if possible, if it 4%, then better saving until lump sum settlement.

4.82 ya, hmm if I am you, I will not brother with doing refinance kind of hassle and pay for legal feel. Except your property already appreciated valu and you think to refinance and cash out the money to some purposed then only you can consider.
