Merge parcels or not?

[Anthony G]

So I have a duplex on a fairly small lot in Indianapolis. It has a small sliver of land that runs next to the lot the house is on, probably like 3'x125'. I'm considering merging these parcels to simplify things if the cost is low or free. I can't see how it would negatively impact me, but I wanted to see if you experts could think of a reason not to do this. Remember, you can't build on it or even park a car on it if you wanted to sell it.
