I was attracted to this niche because of the double digit cash on cash returns.

I have purchased an August lock with keypad and plan to use the keypad only for guests, issuing them a four digit code that is the last four of their phone number, good for only the time of their stay.Cameras outside the properties so I can see what is going on, if a door is open, lawncare situation, etc.Alarm system, I'm trying to figure out if this would be more trouble than it's worth (another thing to break, confuse guests).

I have automated pre-stay emails and the code is always just the last 4 digits of the phone number on file and it's only active during their booking. 

SWARM is a free platform to issue digital regulatory compliant securities.

At least low double digits.  

I put down 60 k worth of rehab plus a 12,500 safety net cash for a huge mess up during rehab and ARV is 416,000, the profits are in double digits based on my calculations approximately 35k including everything mentioned above.Also the experts out there do you feel I have enough of a safety net with these numbers? 

Reasons are - relatively stable economy and job growth, several Universities (Missouri State, Drury University, Ozarks Technical College, Evangel, etc.) in the local area and a major hub for surrounding suburbs/towns such as Ozark, Nixa, Republic, etc.If you favor cap rates, it is easy to hit low to mid double-digits on properties that seldom top $100K (yeah, BIG difference from Irvine/SoCal in general!!).

Nationally and globally we are talking about multi billion dollars market with double digits growth.

I will also be using a Cannon digital camera for other videos.
