First Investment House Hacking and Cash Flow

[Hunter McClellan]

I am thinking about house hacking a duplex in Texas with a FHA loan and am not sure what I should be shooting for in regards to cash flow after I move out. If I pay close to full price, I will pay around $200 a month while I am living on one side. This will save me close to $5,500-6,000 because I will not be paying rent for a apartment. Depending on the duplex, when I move out I will cash flow around $100-180 a month while saving 5% for vacancy and repairs and $180 for CAPEX. Should I be going for more cash flow or is $100 net cash flow okay when the down payment is so low?

Some of these duplexes have window units so should I not be keeping so much for CAPEX? Thanks in advance.
