Not cash flowing on first Duplex

[Nick DiTommaso]

After multiple calculations on multiple duplex properties in start of my investments, I have noticed I wont be cash flowing. Occupying 1 unit and renting the 2nd unit has only equaled out the tenant paying a good chunk of the mortgage payment and leaving me paying for the rest. Now this will be my first home and going through FHA. I am more focused on putting a small amount down payment and having some money in reserves for any extreme emergency compared putting a larger down payment.

After doing the math, calculating rent expenses, vacancy, R&M, CapX and considering all the possibilities in my analysis, I would still be paying a portion of the mortgage payment every month, anywhere from $150-275 per month. I would eventually be renting the 2nd Unit after a year, but does this seem common? I would certainly have W2 income coming in and seems great that someone is helping pay my mortgage, build equity and setting myself up for future success. As though I would not be immediately cash flowing, does this analysis seem a great choice?
