You still get to choose the person who you rent to.. why is this always a big deal just take their application and if they don’t fit pick someone else honestly you get all their info and just choose someone else.

That said... and IMO, at the end of the day, if the property you buy fits into your strategy and you have reserves, it doesn't really matter what the market does.  

I would say, “Thanks for taking a look, keep us in mind in the future if this type of investment becomes a fit for you.”

What are the best apps to use for a general all around app that has the most regarding leases and paperwork for new renters, tax organizing and property profit statistics and any other aspects of owning a rental.

Pros and cons to all of them as you would expect, just a matter of finding who fits best for your specific needs and plans. 

@fred moskowitz suggestion I also downloaded an HP12C app to my phone as I understand it'll be needed to practice some of the financial exercises.

Focus instead on what you like and how the house fits your needs, build the relationship.I would also recommend that you do not run the seller's numbers. 

@Michael K McClafferty I recommend interviewing with several to see what feels to be the best fit. 

Thank you for reading and feel free to give me whatever info you see fit. 

In a way this is a type of interview to see if this person is a good fit to be "your" real estate attorney and not just "a" real estate attorney.
