It is helping me by clarifying everything I read in the books but I feel like I could use a bit more brushing up .

After I got back from downtown my brother treated me to a case of beer.Thats when we were cracking up & brushing up on our techniqes.

Careful painting with a wide brush.

Instead, I just carried a brush around to mash some paint into where he missed and supervise him.

Take the drain plug out run the brush up and down for 30 seconds flush with soapy water problem most likely solved.2) As for the bathroom floor/shower problem. 

Costs can vary a lot depending on level of finish, what community you are building in (fees can vary a lot) etc but for purposes of a very broad brush I'd use $120/SF plus soft costs (architect, engineer, survey, legal etc at another 15% over hard construction plus land, plus site work. 

, brushing my teeth, washing my hands, drinking, etc.

I asked why that was never needed and suddenly it is and I got the brush off "Thats just the way it is".

Things I didn't account for on my last rehab - Misc expenditures like you said.Anything from door hardware, to extra brushes, to a new damn hose on my pressure washer.

Using a good brush and consistent brush strokes going in the same direction give it a better look.
