Cohousing-L Mailing List: Home price for cohousing, over price of surrounding comparable houses

[Becky Weaver (beckyweaver]

Hi all,
 
My group (Central Austin Cohousing) has been working under an assumption that 
the initial price (i.e. not resale price) of a cohousing home will be about 10 
- 15% higher than the price for a comparable (same square footage & 
construction quality) home nearby. In other words, we have been assuming that 
the price for the common facilities and other cohousing-specific costs average 
10 - 15% per home.
 
My question is, what was that ratio for your community?
 
My goal is to get a handle on we should expect, and what we should aim for, in 
terms of development costs/home prices. 
 
Thanks,
 
Becky
