Unless all of your competition is providing this and it is essentially a defacto requirement in your area in order to rent a unit, there's just too many things that can cause problems (legally and otherwise).From a technical perspective, I do networking and server administration for a living and I would be complaining as well especially as I'm assuming your lease doesn't say "internet is for school related usage only." 

In yourpersonal names you can get a conventional loan, 30year loan, for a 4 plex....adding another 4 plex to the same property may cause some issues.  

Even if it was legal you run several risks.  1) You would permanently damage your reputation in an industry where reputation is vital to get deals.   2) You risk major tax implications related to large capital gains.  3) Comps are not solely based on on the units you want them to be based on.  4) Even if this hypothetical plan worked exactly as you laid out you would be extremely over leveraged and underwater on the other units as you pulled out falsely inflated equity. 

One of the strangest things I've seen is a tenant complaining that a toilet is too old thus causing him to miss the toilet (obviously the toilet was not the problem).

A few months ago, Hurricane Harvey hit Corpus Christi and caused minimal damage.

The tenants in my condo (upper unit) left the water running while filling a bathtub, resulting in water leaking into the downstairs condo.My tenant has $300K liability insurance, but apparently it doesn’t include any negligence water damage.

It’s interesting that you use the tax bill as a cause for the recession NOT to hit - many people blame the tax bill and subsequent increase in rates as an indicator that prices WILL drop 

ITS made with a raise in value  caused by a serious raise in rents and for appreciation and market driven lower of cap rates.. 

Thank you all for your support and advice I will continue to work on bettering myself in this kinda buisness cause I know it is something I wanna do I greatly appreciate everyone’s input 😁

I need someone to go through the property, document any problems, damage, etc.
