The company that has reached out to me looks legit but they are offering to pay about 50% more for rent so my "too good to be true" alarm is definitely blaring. 

It's not like he or she will come inspect your camera installation so a written "do this, don't do that" isn't that expensive.And I really don't mean to be a downer or anything but if your tenant is concerned about safety, solid deadbolts, sturdy doorframes and a monitored alarm would be worlds better than a camera system that only passively records things.

Does a security alarm system help?

Hello,I have seen old posts on the topic, but not recent ones.What does an ADT alarm entail and would you recommend allowing your tenants to put it in place?

This issue can be avoided completely by transferring the property into a land trust.While a transfer to an LLC will cause alarms at the bank and prompt them to send you a letter, a transfer to a trust will not.

My 8 plex needed a roof, heating system, a monitored fire alarm system, and remodeling of many of the units as they turned over, not to mention many 'smaller' plumbing, electrical and cosmetic repairs.I bought it anyway. 

This is why literally EVERYONE at high level comprehension in tech is wailing alarms full blare now.

I DID NOT intent to cause alarm or worry to anyone.

Comparison is the thief of joy. 

I got rid of the thief, but they have given me grief ever since and only gave me half of the $425 deposit, refused to pay the rest.
