I was in your same shoes about 5-6 years ago. 

Has anyone had success showcasing land for sale - online or otherwise?

In defense of the dogs: I have 3 rescue pitt bulls myself and aside from shoes or sunglasses, and dead grass from pee, have had no property damage from my dogs.

I am around the same age and was in your shoes earlier this year, let me know if you have any other questions and will give you my perspective not as good as some of the guys that have been in it for a while but hope I can help.

What Elbert Dockery posted makes sense perfect sense . . . essentially walk in the shoes of the people to whom you wish to sell a property. 

Too many in your shoes over complicate real estate and spend unnecessary time and expense on tax planning & asset protection and in doing so, take away from the real estate.

By putting yourself in the shoes of the other person, you can clearly see where they are coming from and that may help you to understand that person better.  

Try to put yourself in your friends' shoes, and it will be easier to understand this type of resentment. 

Buy the heirs' interest in the estate via assignment and then step into their shoes and become the bene and the admin/exec.

If I were in your shoes, I would do the following:- set 6 months worth of income aside in a HYSA to save it for a rainy day (this will help shield you if you lose your job, or if something goes horribly awry with your investment properties)- open a Bank on Yourself life insurance policy (this is a specific type of high dividend paying whole life insurance where you can borrow against the cash value in your policy at any time and the money will continue growing as if you never took out a loan.
