As a renter myself at one time, I think it would be much easier to swallow the increase of you gave them a very clear picture of what you intend to raise the rents to up front and created a plan to gradually increase over the coarse of 6 mo to a year.

My husband and I are in our first NOMAD home with plans to use this and the conventional way of purchasing several buy and holds, as well as, lease options for some short term options to boost cash for the long term purchases.  

Can you explain your planned timing on these moves?

I plan on staying in it for at least 6 years.

If I were to purchase a rental property that my daughter would live in, could I "charge" rent and pay myself (or LLC) with tax free money from the 529 plan?  

I don't ever plan to wear a bullet proof vest to go and collect rent :).  

What I plan on doing when I get better.  

I have a full time job and don't plan to quit anytime soon.

The back half of the property already has a well and power pole from a mobile that was previously there so selling that separately would net us an additional 5-10k.  

I haven't yet installed any, but I plan on doing three this month.
