When they agree to paying a larger security deposit it shows they have a stronger financial position (vs. living paycheck to paycheck) and it provides them extra motivation to take care of my property. 

I find that unless a seller is highly highly motivated, these aren't credible or they get rejected (especially if the seller is working with a real estate agent or attorney).

Do you mind sharing a bit about what you are looking to achieve with your RE investments?

Whenever i call, they either don't want to speak , and most don't soubd like they are motivated.  

Motives notwithstanding, do I have a legal right to force them to leave the premises or do they have a right to remain on the premises during inspection?

But like the others have said, there are many ways to achieve it.

Unless you have Full Replacement Coverage, you get hit with this - - and it's the motivation for having that coverage.I have a great policy with Farmers and 100% replacement costs from a tenant caused fire.I can't imagine Buy&Hold without Full Replacement Coverage

I think you will have better luck with an estate sale or a motivated seller. 

Looks great and is definitely motivating me to really stick with my real estate goals!

Investing has always been my long term goal and what motivated me to become an investor.
