Your accountant can help shed light for you on which is appropriate for you.I would not change the deed right before the sale and start of your 1031. 

I understand I will not be able to leverage some of the tax benefits available to traditional landlords while I am renting to her and want to understand 1) what I am missing out on and 2) any legal, creative ways to access the rental tax advantages.Thanks for your thoughts!

The other option is to use a traditional bank as you mentioned.

For security I like Ring products as they are low monthly costs ($10/month), yes the equipment costs up front may be a few hundred dollars but keeping your monthly costs low will increase subsequent cashflow, traditional alarm companies can be 40 to 60 a month.

. - Get a traditional loan after mom passes (Total purchase price-what we have paid off= new agreed upon purchase price of the home)?

I am not able to qualify for a traditional loan due to my lack of job history.

Traditional investment property financing is probably not appealing. 

For a traditional STR you might want a place with a cool spray painted wall to take pictures of and post to social media. 

Be super careful when using traditional loan products as to not commit mortgage fraud. 

So I then gave this contractor the green light to begin the work.
