domain .

This one is very hard to tell. The word ''catalog'' is less popular in some countries, but in others - yes, a lot. But then you have ''condo'', condominium, basically apartment blocks (not villa or even townhouse). Yet I think it's rather ''yes'' than ''no'', I would defineteley hold on to it. Some construction company, municipality or even city can use it.

Hmm, I agree with @VadimK Iberica

Condo Guide / Condo List would be nice. The word "catalog" is a bit like a "brochure" ...people say brochure related to property, but I wouldn't necessarily gel that in a domain brand (as the super ideal thing ...I'd go with guide / list at the replacement as mentioned, or similar)

I'd hold. The alliteration of 'C'ondo-'C'atalog gives it the pass IMO, generic yet could also be brandable in the eyes of someone.
