I'm trying to come up with some simple per square foot room calculations for rehab. For example it seems like sq footage divided by 10 gives a good estimate for number of 12 foot drywall boards needed for walls and ceiling. For example, this equation for a 12x12 room would yield an estimate of 14 boards. Then you multiple by your per board finishing cost.
I hope to do the same for hardwood, laminate, roofing, paint, etc. Then I can put together a sq foot estimate for a room.
For example, I want to be able to measure a bedroom that needs drywall, paint, trim, and flooring and come up with a quick estimate for the rehab.
Anyone got any numbers, equations, or estimating ideas they'd like to share?
I have found rules of thumb like that to be just that, far too general rules of thumb. What I do is I make a log of every job I have done, and log how much that job costed. So I can make a quick estimate based off of that.
