There are MANY skip tracing options.

Are there no better options, like a REIT's, Stocks, Bitcoin, or other things?

If the renter has no way to take care of the pets and you do not want to keep them due to their cuteness and friendliness, then an option might have to be a no kill shelter.https://www.nokillnetwork.org/

I am interested in acquiring a 10-acre lot with a house listed for $1.6M in a Houston suburb and would like to investigate financing options for building a commercial structure on the property.

Padsplit may also be an option if you want to be a little less active in managing. 

I turned to the Diontalk Binder strategy which educates the tenants on the current price of market rents, section 8, etc, and what I could potentially earn if they were to move out ( In this case being 1500 for a 3b 1ba). they then realize this and know paying a $400 increase (36.6% Increase) would be the best option vs moving out, living in cheaper housing, or going to market rent in the area.

We do it up the hill Reno and with a good agent they can give you all the options and guide you through the process.

Properties below this threshold present additional risks and more limited borrowing options.7.

Some Pros are they were built better back then in my option. 

They have the option in which you do it with them and the other one in which they do it for you.
