If not going Turnkey, I suggest crafting what you want to get out of your market and why you can do it better.

Any advice on ways to craft such letters?

And @Natalie Kolodijs right about losing the significant benefit of the step up basis when you pass as long as the property is in your name.But,  I'll bet you could craft a strategy with your estate planner to combine a 1031 exchange, a lease to the kids, and aggressively annual gifting of equity interest as a way to get where you want to while keeping capital gains at bay.

I am hard working and believe in dedicating myself to my craft.

Hobbies/interests include travel, hockey, golf, snowboarding, sailing, and drinking craft beers. 

Also, the owners may not respond to a regular letter, but they might respond to a well crafted attorney style mail or Urgent Notice regarding "xxxxxxx san, antonio Tx)

Once you know what their problem is then you can craft an offer that will help them out of their problem.

Currently working in Accounting and Finance, I would like to pursue real estate investing and move towards creating wealth for myself and enjoying my craft.

Then spend all your time perfecting your craft.
