for birthdays, yearly upgrade of their choice when they renew their lease (replace old appliance that isn't going to last much longer, replace flooring- things I might do if the unit was turning over).  

I got a birthday check in the mail (yeah I still get those believe it or not), and went to cash it.

But the status quo is to not ask, I guess...in the CC&Rs it says we have to ask for every exterior change except annual flowers!

A good bird dog is a bridal shop owner or flower shop.

For example, I have had to leave my husbands birthday dinner before to get something handled.  

@Julian IllingworthLooks like a good cash flower but I agree with @Aaron Montague that the maintenance and capex looks light.

We are getting there- currently at 10 units since we started 2.5 years ago, and we have 2 more under contract for 6 more units.You got great advice already, I agree with no gift cards and no bbq, but do think we might implement a small gift card sent on the tenant's birthdays.  

If I were starting today my foundation would be wholesaling with a side of lease optioning.I started investing a week after my 16th birthday with my 19 year old brother, you needed to be 21 then to contract but he was married thus could contract for us legally.
