Take the toilet out without damaging it, put a sanitary cover over waste hole, put toilet on shower floor.

You can figure out your income and expenses on the back of a napkin and pay down your mortgage faster.  

Quote from @Scott MacComb: I have had contractors just do a small list on a paper napkin, and some do something on a word document.

We gave him an old lease that said he didn't have to pay water (we newly split the utilities in the unit) and he noticed we charged him for water and then we refunded him (although he continued to send us pics of his napkin math that says we didn't refund him enough).   

But having that initial plan- hell, even a scribbled outline on a napkin; will give you something to pivot from when the market throws a curveball.

I mean like you said we don't all need white table cloths and linen napkins when we go eat.. 

Paper napkin math says skinny deal. 

Cheers   Both cap rates and cost per door are back of napkin analysis to see where the current numbers line up.

Don't use napkin math 'rules' to make investing decisions on.I hate the 1% rule, for the same reasons I hated the 2% rule a handful of years ago. 

Optimally, the lawyer or the firm should be familiar with public infrastructure that developers are typically asked to pay for, such as road widening, turning lanes, new roads, sanitary sewer extensions, new water and electric extensions, fire hydrants, etc.
