Flat does a better job at hiding waves in the drywall or nail pops that can happen.Walls would be fine with either flat or eggshell.  

Hey Garmeon, nail down the items that you can on your own (1) rents (2) vacancy (3) management (4) property taxes (5) insurance and then estimate the lesser known/variable items such as repairs and cap ex.  

Its going in the living room and hall and I will probably nail or staple it down.

If stain remains, rust remover (Oxalic acid solution) or bleaching may be necessary.Do not use ammonia or alkalies.NAIL POLISH: 1.

Dang, Jerry nailed that to the barn door!

I agree @Martin Zawarski , I was trying to think of advice I could pass along to flippers from my world as a builder and you nailed it.

@Oleg k I have never flip before, I am learning to do my first flip this year.Please take it as suggestion instead of criticism.I think@Joel Owens nails it. 1) the curb appeal 2) the flooring from the living room does not flow through with the kitchen. 3) the front entrance stairs & the wire fence really throws away the interest of potential buyer.

I have also seen People liquid nail wainscot to the wall tile and put a brick mold on top as a chair rail to cover the gap.
