I than thought it was tenants, all the "what if's"; what-if they have a fire, what-if there is a shooting, dead body, drug raid, break-in, squatters, feces art, etc etc etc.....   

@Jae Yoo you should read your PM contract very thoroughly or even hire an attorney to do so, before thinking you can just break it.How would you feel if a tenant just broke their lease with you?

I offered to break the lease but tenant did not take it. 

@Daniel Baker What do you mean by breaking even??

I’ve been investing in RE for 10 years and hitting 19k/month profit not counting things breaking or vacancies.

I see big price range with these (from $200 to over $4k) and wanted to know if you can get a decent one without breaking the bank.

You can buy a set of five for under $300, subscription for the recording software is $10 a month, then the cost of WiFi or hotspot.If you've already had a couple break-ins, you are obviously in a high-crime area.

I took a break because of my trucking career with being over the road for three weeks at a time.

also look at the tongues, some are very thin and break easily. 

I care about collections, not just bodies in the building.
