I am looking to purchase a four-plex and use the rented units as income...

Much more info needed to your question.. Are you looking for an investment type property or do you plan on living in one of the units? The short answer is, Possibly.. There are grant programs out there to help with the down payment, but they typically are only available on single family homes or condo purchases.. not on a 4plex. However, FHA will do them with 3.5% down.. (again, you have to live in one of the units).. and you will need funds for closing costs.. Also, when it comes to calculating the qualifying rental income, we have to have the appraiser give us rental comparable's for the area, and then we take that number by 75%. Example: 4 units, you live in one, rent the other 3 out. Appraiser says the rent for the area is $1000 x 3 units = $3000 per month rental income X 75% = $2,250 income added for qualifying purposes. Assuming the rental income is high enough, it's possible you can make enough income off the projected rent to fully pay for the mortgage payment.
