Depending on owner's intentions, there are 2 downpayment requirements for investment properties depending on whether the owner intends to live int the investment property (duplex, triplex, fourplex) or not:

5% downpayment if owner is planning to live in one of the units in the duplex, triplex or fourplex with maximum amortization of 25 years
20% dowpayment if the investment property will not be occupied by the owner and maximum amortization of 30 years

However, it is important to review one's goals over 5-7 years and understand the downpayment requirement if planning to buy additional properties. The number one challenge for real estate investors is running out of capital (downpayment). It is important to plan ahead and divide the monies accordingly to achieve the long term goals. I have met with too many investors who had the need to restructure their mortgages since the focus was on the next deal and not the long term plan.
