Much of what I have found says that cashflow is king and that net worth just looks good on paper as cashflow really enables you to live and invest now and banks look more at cashflow and debt/income than they do your net worth (my current debt/income is 14.9%).

I have a Network Attached Server (RAID enabled with 5 hard drives) with 10GB of space. 

I'm new to all of this and would really appreciate someone running through the numbers and theory with me to enable me to better understand whether or not it would make sense for us to house hack now. 

As your renters pay down the mortgages, your net worth increases, enabling you to obtain better financing on your next deal or deals.

I have been listening to a man down in San Antonio that use to have about 15 rental homes and they almost totally broke him when he was able to ask for and get a higher non-refundable deposit,  make the spread between the rent and the debt payment, and often they would make and pay for their own maintenance and improvements, and often they would not take their option and enabled him to do the same thing again.Even though they started out leasing, they tended to treat the home as theirs even though it still belonged to him. 

The middle ground, is using a high quality/ full service management company that has a lower cost structure (more tech enabled) and can give you great service for around 15-25%. 

You'd have to check with customer service on compatibility with your particular units but payrange has great bluetooth-enabled apps for laundry payment systems. easy to DIY install with youtube videos. no monthly fees and low upfront hardware acquisition cost.

One being "rich in experiences" and the second one that enables the first is to live well within your means.I have always done the second part and it always amazes me how others don't.  

If you have a high Cash on Cash return then it enables you to reinvest your money quickly into other properties.So when we take all of this together we get the profile of the ideal buyer of this property: a real estate professional that already has a lot of cash on hand and believes that this market is going to be hot for the next 5 years.

If you are tight for cash you could just shut the door on the unit that needs 25k rehab and fix it later when you have hopefully made some money.You could perhaps get a better return if you spent that money upgrading the other units and prettying up the property-would that enable you to get higher rent?
