About 15 years ago contract for deeds were virtually eliminated in Texas by legislation which not only limited the benefits of using a CD, but introduced severe penalties for even minor issues of non compliance.  

I about gave up when Inslee changed the rental laws here in favor of the tenants, but I was introduced to a very good property manager and have had good luck since. 

Just one idea, but probably a dozen ways to accomplish this. 1) Father drops the property into an LLC, if it isn't already2) You and Sister are introduced as "profits interest" members of this LLC3) You can then structure how the profits are shared, but Dad owns all of the appreciation that has already occurred, and would get a step up upon death. 

Definitely, you will introduce a different demographic from vrbo then you will with airbnb. 

My name is Ron, and I would like to introduce myself.

Happy to introduce you to a tax CPA who works remotely. 

First just as a simple welcome and introduce myself, coordinate security deposit payment, asking if they'd like to see the property prior.

Just wanted to introduce myself.  

The AAPL issuance was a good start but BP can do better and has a better platform for this I was first introduced to HML term in the mid 70s and not sure how many decade before the term was coined.. but its been that way to me for 50 plus years :)

My biggest suggestion would be to find some local meetups (https://www.biggerpockets.com/forums/521-real-estate-events-...) and introduce yourself to the host.
