Hi Gabrielle,It looks like you want to purchase a duplex and rent one unit and live in the other? With a FHA loan, you can put down as little as 3.5% of the sale price but FHA has loan limits...if not qualified for FHA loan then most likely 20% down but I also have programs that accept 10% down. This all depends on credit, income, loan size, purchase price, etc. If you would like a free quote for your situation, you can call me at 323-600-3735 or email at firstname.lastname@example.org. Look forward to speak to you.
