I am no longer emotionally tied to this house because of all the work. 

I seconded that emotion.

If no catalyst is present to trigger the emotional desire for a seller to discount, then there is no bargain to be had.I'm not here to discourage you, merely to temper your enthusiasm and stay realistic. 

Sounds like this situation has gained an emotional element beyond the just the frustrations of a steep learning curve on the business side.  

All good platform sales start with emotion and motivation.

Not by your choice of where to live which is often driven by emotional factors.And even if your choice for a place to live happens to be a good market to invest in, given your "traveling lifestyle" you will likely be living elsewhere soon enough, leaving your property behind.

I would take all emotions out of it, if you had them sign a lease agreement then do what the lease states and take action that the law allows.

It takes discipline and hard work and sometimes finding a way when there is no way.  

This is just a thought; keep emotion in check, it will not help you & refrain from using adjectives referring to a tenant.

It is an emotional transaction - these folks are going to be put out of their home - where are they going - what's their problem -unemployment - sickness - drug addition - death in family ----incarceration?
