From that, I pre-screened which ones I can meet when I physically inspect the property.

It is based on facts physics action reaction period.

There is tons of other info to look at with a commercial property such as underwriting the financials along with due diligence on the physical structure.No legal advice given. 

If you have a hold over, they should have been taking much more action beyond waiting for payment to come in and telling you that they can hire a collections agency for the rest- they should be getting the tenant out, assessing both physical and financial damage and settling up using their deposit. 

If you proceed in this manner, be sure to fork over the fee following their departure or on the day of the move when you physically see the moving truck and their belongings exiting the door.

(Had to pay them but was worth it) Tenant was not allowed to enter without me physically being there, and they had to schedule it this way worked out best for me less out-of-pocket.

I don’t use a physical application.

Regarding chasing down tenants, I highly recommend finding a demand for nonpayment of rent form used in your local area and physically posting that demand on your tenant's door whenever they do not pay rent within the grace period.

Unlike stocks, houses and apartments have a sort of emotional appeal given they're physically there.

I then asked her to please tell me the providers physical business address, twice and was not given ananswer.
