It sure would be a pain to throw $700 on a repair only to have another issue next year and replace he furnace then...

Evictions are painful for you (cost money, create repairs and vacancies)... you're better off avoiding the situations all together through conversations.

I don't even buy 2 bedroom units because they are a pain in the butt to rent.  

There is GOLD in that graveyard of old properties you just have to mine for it.By contacting those agents or sellers you can find out if the sellers pain threshold has reached a point where they will let the property go at a great price.

It's a pain to get it put back, so the back just doesn't want to deal with it.

Private money is everywhere just identify the pain and offer a better solution.You can also look at a business line of credit companies will give everyone in the LLC with 720+ credit 50-150KPaul

Which we all know can be painfully inaccurate. 

.; contact BBB; Bad reviews on Angies list; Yelp; Google reviews; just try to be a pain in the butt; call TV stations to see if they take your story etc. 

There are a lot of specifics about your property & yourself that we do not know, but consider the following.You have ALREADY weathered a MASSIVE (maybe a once in a two-decade) move in oil prices lower ($100 to $40), and are by your comments, you seem to still be doing well with this investment.There may be some more pain in the short-term (e.g. continued layoffs in the services sector), but the eye of the hurricane has likely passed.On a 5-10-20 year basis, the oil/energy will be fine.

I have a long time alarm contractor hardwire them (lots of batteries are a pain).
