Costs of selling a flip

[Bryan N.]

This has probably been answered, so if someone has a link that's fine.  I've searched, but couldn't find it.  

I bought a property from a slumlord which I discovered after the fact.

Anyway, it's basically become flip at this point.  Minus new windows and shower inserts it's been replaced.  I asked my realtor to comp it and I can expect to sell it for more then I realized.  Even if I get low balled I'll get all my money back and a free education if I understand all the costs correctly.  Worst case scenario it will be a really nice rental with good cash flow.  

I'm going to crunch numbers this week, but here is the costs of selling that I'm aware of.  I know I'm missing something. 

Realtor fees 4.5% (my realtor will do 1.5%/3% for other agent). 

3% closing costs to buyer (standard here)/2% if it's an investor.  

Taxes - based on "profit" after purchase price and expenses to rehab at my tax bracket. 

Any other seller concessions.  

What else am I missing?

Thanks
