And luckily I had moved my tractor and implements off site.

I have 12 individual units and I would like to implement a system to collect rent, track expenses, etc etc Any and all input is appreciated. 

A lot of SFRs.Also, let's say a crazy loosening of the zoning restrictions is implemented. 

You really sound like you know what you are doing and have implemented the tech the way we all plan to in our heads but never seem to do.

Rent Increase: Is it more advisable to renovate or to simply implement a modest rent increase to around $2250 (about a 5% or more hike)?

It sounds like with a 200 unit complex that's stabilized and just has a small value add component/utility cost reduction or RUBS implementation, you found a very low risk deal without much speculation and with a good amount of upside.

Just for the record - these strategies are not ones I would ever implement because I have a heart - but for the heartless ..... and Yes I understand that sentence does not belong in anything posted by someone with an Ayn Rand avatar.

Implementing Scale-able Systems is the first step for us. 

You could look into an IRA based self-directed program in that case.While you may be able to hold the funds of your plan with an institution like Vanguard, they will not be able to assist you with implementing such a plan.  

The IRS regs on much less stringent on 401k funds and you can even use debt in some cases without triggering UBIT.
