Provided that u can get a valuation higher than 260k, say 290k, then u can borrow 90% base on 290k instead of the selling price 260k.
It's quite a hassle as u might need to go thru quite a number of valuers that can give u the highest valuation. But it's part of the learning curve.
Then u hafta make sure the seller is willing to sign the SPA at 290k. Of course you'll hafta bear the additional RPGT (if there's any) and higher legal fees. But at least u get to loan 100%.
