Frequently asked questions
What is a top-up loan?
Top-up loans are additional borrowing on existing real estate collateral, using the difference between the valuation price and the remaining debt as a form of "home equity loan." Interest rates are often much lower than personal loans.
How much did the top-up borrow?
Maximum Top-Up Amount = (Assessment Price × 70-80%) - Remaining Debt Example: House Assessment Price 5 Million Remaining Debt 2 Million Maximum Top-Up Amount (5×0.8) - 2 = 2 Million baht
Top-up vs. personal loan. Which is better?
Top-Up is better with collateral: Much lower interest (6-8% vs 18-28%) Higher amount, longer repayment period, but more risky because of the collateralized home. If you can't pay it, you may be foreclosed.
