In all the time they've been there, has any investment been made into their units, and are they identical to the higher market rent apartments? 

The purpose of hiring an unrelated party like an attorney or a CPA is to hide your identity. 

An identical property sold for much less than list price 2 mo back, so I'm hoping to negotiate down to at least close to that.

.- The seller has 2 duplexes that appear identical in Columbia county between Madison and Lake Wisconsin.- The pro forma rent is listed for $975 / month (estimated from gross income).- Each unit is 3BR / 2BA,1200 square feet.

(BTW, just about every house in parma are carbon copies of each other, they all look identical so once you see a few, you've seen most of them.)  

Your name, your identity needs to scream "we are awesome, the best, no one comes close to us).

@Toneisha Moore As an agent, you will need to begin building your identity as a trusted advisor in wholesalers in your area.

When your property generates $30,000 and the identical property across the street generates $12,000 that adds value and build equity for you.  

But because of that you have 3 billion and 1 carrot sites that look identical.

If you are dealing with suburban properties that have lots of identical comps (town houses, condos, same build style for SF).
