Market is not generally fast moving so having a good agent is key. 

Got it under market price and we're cash flowing today

You’re making a smart move, and that kind of foresight will pay dividends over time.Now, let’s dive into your question: Is house hacking still a good option in today’s market?

As someone who deals and talks to real Private Lenders (small shops run by a guy who lends his own capital and doesn't use big box), they have a hard and fast business model that produces the rate of return they need to remain profitable and curb the risk on their cash.So the best product for a budding fix and flip investor is the bridge loan which includes acquisition money and construction money. 

Do you have the professionals you need to start an LLC, do the proper real estate/tax accounting, solid contractors to rehab or prepare the property, and a property manager to handle the day-to-day operations? 

@Shawn Tuma & @Chris KayVery difficult in today's market to cashflow putting 0% down:(5-10 years ago it was possible, but prices have increased faster than rents.Your best bet is to find a property that needs work, but will still pass a VA appraisal/inspection. 

We have done tons of non-occupied flips too (fast method).

Education via trail & error is easily the #1 worst way to go about anything today UNLESS your an explorer, inventor, revolutionizing and still all of those have a whole lot of training and education backing them. 

@Jeffrey Evans$1000 to find a deal I agree - there are tons of syndications and funds available for real estate investors today since jobs act that you can invest in and do your own research on.
