@Eliot HochbergYour experience is not uncommon.  

And your feeling is not uncommon.

So. it’s not uncommon to request proof of rent depositsvia bank statements and corporate/LLC tax returns.

Its not uncommon for sales offices to offer significant discounts to clear out their remaining properties, even after previously declining to sell to investors, indicating a change in attitude and the need to meet their close out deadline. 

Finding one that charges between 20 and 10% of revenue is not unusual and it's also not uncommon to see your profits be comparable to pre-management except with significantly less toil.However, which of the many solutions is right for you really comes down to what you want to get out of it. 

This is an uncommon occurrence, but it is something that happens with even the best of homes.

I'm not saying this is the case with your agent, BUT it is a not uncommon practice for agents to over-value properties in order to get listings.

These days, it's very uncommon (almost impossible) to find a perfect, quirk-free, A-grade property that works as an investment (I wish it were that easy!).

One thing to also know is that while "due on sale clauses" do actually get exercised, it is relatively uncommon.

They may increase rent at renewal (usually they do), but it’s very uncommon for landlords and/or pretty management companies to charge a renewal fee?
