I never hold my breath when it comes to the city, but it is supposed to be a simpler, over the counter type of plan check.

Second is to underwrite deals conservatively now so you have breathing room as the market turns.  

Both filtering for sales and advertising that you are wanting to buy. 

Don't get me wrong, obviously the numbers and details are important, but keep it simple; when you finance, will the rents be enough to comfortably cover the debt service and other expenses (vacancy, capex, PM, whatever you budget for) and leave you some breathing room?

I have never tried but I think it goes through their filters and URLs are removed.

Items that are consumable - heater filters, light bulbs - the tenant should be expected to maintain as part of the lease.

This is IMHO the real way to filter out the turds. 

I do not have much knowledge knowledge of the Atlanta market, but I do use Zillow as a tool to figure out hot spots by filtering it as "sold" instead of "for sale".

First concentrate on getting to a level of income that allows you a little breathing room so you're not worried about paying next month's bills. 

I have used Listsource, but when I filter for "residential multi-family" it only produces one property.
