Leo i dont think you have a cheance if offering only 25% of their asking price, if you are thinking of deducting 25% from the asking price that would be more in line. So you know you are going about it the wrongf way, there is no magic percentage amount a bank builds intio the price and then deducts so you think you got a deal. each bank sets a time frame in how long they want to wait for the property to sell. usually 1-7 days, 30 days, 60 or 90 days. after each month they lower the price accordingly. they set the price by using todays market value less any repairs needed and deduct a percentage already from todays value depending on how quick they want to sell. in most cases a bank wanting to sell within 1-7 days takes 20% off of todays value, 10% for 30 and 5% off for 60% and at todays value for 90.
You need to deterimine what todays value is and base your offer on that, not what the bank is asking. good luck with your purchase.
