quite simply, the bank will issue/approve a loan based on RM420k which is your buying price & owner's selling price..
complicated version, the bank will definitely go through a process of valuation with proper valuer. If the valuer values the house at RM420k or above, you hv no problem getting a 90% loan based on RM420k
but, if the valuer feels the house value is e.g. RM400 (or whatever value) max, you can only get a maximum of RM360k which is 90% of RM400k. you will hv to fork out the remaining balance to pay the owner...that is if you really like the house, the ori owner didnt want to reduce his/her price & you willing/able to pay the balance in cash.
bank will 99.5% of the time go with the valuer's value even though the owner claim the value is higher.
it doesnt matter what 'profit' the seller is making..30k or 300k doesnt matter to the bank as long as bank's valuer feels the seller is selling at market rate.
you can even ask/pakat with the owner to state that his selling price is RM460k (if the market value is ok) but actual selling price is RM420k...so the bank will release RM420k to the owner which is 100% so you dont need to fork out any money to buy the house...can save RM40k for renovation or invest in other property
this is known as sub-sales. you will need to hire a lawyer or use the lawyer your bank recommends you. you will need to pay a deposit, & whatever balance (minus what the bank will pay as your loan) through your lawyer.
bank will release the loan/money directly to the house owners, again through the lawyer and will notify you once money is release.
whole process takes about 3months.
if you need a loan and/or lawyer let me know

but i'm not a banker & i will not make any profit from you. i'm just able to help.
