The concept that the county was giving them 2 years to fix the problems should indicate the length and breadth of the violations.

My apologies for the length.

We then used a concrete pump to fill the cells full of concrete for the full length of the wall. 

If your length of residency is unknown, why not focus on wholesaling until you settle down?

So as far as the length of the pay back period it should be as soon as you can and not a set time.

If so, then all that would be required of you is to serve him 30 day (or 60 day in some cases) notice that you will be raising rent.If he will be on a 6 month or 1 year lease (or whatever length of time for that matter), you can write it into the lease that the rent will be such and such until this date, and then it raises to the new rate on that date.

I am especially concerned because their lawyer daughter has gone through the lengths to pull public records on my unit and is making threats to take action against me and the HOA.

Figure out your ROI -- I prefer IRR for something like this as it will take the length of time the money is invested into account. 

While I have given tenants my number and speak with them directly about problems or issues during my inspections, I would go to great lengths to make sure that I do not undermine the PM's authority as it is critical to insuring my investment as I am so far away.
