(if you have older systems/roof, they essentially do the coverage based on the current value of those systems instead of what it's going to cost you out of pocket to have them replaced).

Quickbooks can't cope with divvying up my new roof or my insurance and water bills 60/40 while also allocating 100% of my unit turn costs to Unit 2.
