I have found that when I don't invest to keep the rental property in top condition, tenants get aggravated and it's difficult to deduct from the security deposit (during the turnover) if I don't have it in the best condition.

Less aggravation and your more likely to get the return you are expecting.  

.- As I said- for an absentee landlord not worth the risk, aggravation and time.

I should have bought a similar house in the neighborhood for $55,000 and saved myself the aggravation.

Oh my goodness, wholesalers aggravate me.

For years, I have felt that I needed a local CPA, and it has caused me much aggravation as a result of the problems I've encountered. 

Now you are facing all of this aggravation and possibly a long term vacancy which may ultimately end up with you renting the place out for the same amount as you were per month.

Probably not worth the aggravation to issue demand for full rent and proceed to eviction.

If you own a park & rent the lots, you will probably do well without a lot of aggravation.

If it was a real aggravation to get the funds, I would definitely hold them and do some shopping for another property.
