You've stumbled into one of my people's major character flaws...once we walk away from something, we file it away as "done" in our brains.  

A lot of bad cases start with facts similar to yours; seemingly ideal clients that make complaints as to seemingly trivial matters, but oddly enough your perfect rental that has never had any flaws begins to have dozens of issues in the span of a month.

The one recommended on BP (Smartmove) has that fatal flaw.

It is a flawed question.

Once I uncover more details, I'll be able to make a more definitive decision.

There are loopholes and flaws in the system but I reached out here because I just couldn't find enough credible information in one place.

It was "fixed," as in it was not really fixed, in-fact the fix was very flawed, but it had the appearance of fixed (the reason to always hired a licensed contractor).  

Now we have uncovered the fact that they are not using our furnished lease, providing us tenants with criminals records and worse, and collecting late fees from tenants but not crediting them to us.Recently I partnered on a few houses with a friend of mine and he is now like a terrier on a mouse - once he found an single issue he went wild investigating.

In answer to your question, the screening is where I uncover some issues and thus return the deposit.I like your idea of doing a block of showing and then reviewing applications on X date.  

i will throw in my newbie-the-world-is-a-flawed-one as well - with enough money, one can buy all the houses (SFR) in a neighborhood and sell them at whatever prices he/she wants.
