Haven't read the analysis, but I'm sure it is sound.
I deleted every low-level building that wasn't 12/24/48 hour, and even deleted some of them that were within this synch range.
Why? Because I didn't like them any more. I spit on them. They paid for themselves many times over, so I deleted them without a care.
Some guy wandered into my hood during demolition and started meowling on about ROI and the fact that these buildings were 'pure profit', so I shot him in the face and set fire to his spreadsheets
The only early stage buildings I have now are 2 x L10 Houses (they will stay forever), and 2 x L8 Gun Shops (will probably let them stay permanently too).
On the 'at risk of demolition list' in this order are a Warehouse at L7, 2 x Pawn Shops at L7, and 2 x Tattoo Parlours at L7 - these can stay until I need the space for better buildings.
For purely aesthetic reasons I do not want a big sprawling hood, I want to keep it trim, and ultimately only have classy buildings.
Those damn Crematoriums are uglier than my wifes Mum. They will have to go one day too.
