If you know what type of return you are looking for from a turnkey investment, then you craft your questions to see if you are going to be happy with them before you even get to a return question.To put it differently, if you go in asking what a companies' returns are and they give you a ridiculously good sounding number like many are going to do, you are automatically interested.  

OK, I am exaggerating to make a point, but there are at least three main things going on here. 1) many of the deals you are hearing about came from purchases during the financial crisis when property values were depressed, a lot of those investments have been sold and the money made. 2) When you hear 15% IRR, you are hearing both successful deals that are outliers, and 3) you are hearing deals by people who are really really good at their craft.

Many are using carefully crafted lease option deals, rather than seller financing, when dealing with owner/occupant buyers.

We would use that contract and title issuance to craft your exchange documents.  

Account Closed I'd get an attorney to craft a template for you that's specific to not only your city/state but also speaks to your Do's  & Don'ts as an owner.

I'm also wondering if there's anything unique that I need to consider about crafting a deal knowing my grandmother will likely not be around much longer? 

Go find a niche, pull the trigger, and then strive to get better at your craft each and every day. 

I am trying to see how I should craft my content to either include both options or separate out the two.

Tons of useable craft supplies.

The question you have to ask is if you wish to affect property title (hardball) or just contractual (softball) and craft your bulletproofing methods around what is acceptable practice in your state.
