With a Conventional Loan you can buy a SFH, Duplex, Triplex or Quadplex with as little as 5% Down if it is your primary residence as long as you have the intention of occupying one of the units for 1 year after closing escrow.This is the strategy I have personally implemented and have assisted many of my investor clients in doing the same. 20% Down is also beneficial as it keeps your payment low but it does limit your ability of buying more real estate faster.i would be more than happy to discuss the different strategies with you over the phone or in person.
