Is There A Better Way To Price Construction Than That Presented in "Ultimate Campaign"?

[DungeonmasterCal]

I have a player who wants to invest some of her hard earned cash into building affordable housing in her home city, which is still reeling from a dragon attack a couple years ago. But the rules in "Ultimate Campaign" are, IMO, ridiculously and needlessly complicated. I borrowed the book from a friend and I hate how it describes the way calculating construction costs are done.

So, is there a 3PP product or a simplified Homebrew method for pricing construction of houses, apartments, and the like?

Thanks in advance,
