I recall when the .Condos TLD domain came out thinking they sounded nice.
Miami.condos
NewYork.condos
LA.condos
but between early access fees, premium renewals and uncertainty about finding a real estate agency willing to pay enough to generate a worthwhile ROI at a portfolio level, I decided to drop the idea.
Many newbies are regging new TLDs where the keyword combo does not even make sense and where even in .COM would not be that great of a domain.
MiamiCondos.com's value IMO has little to do with the renewal rate for Miami.condos. If a Miami real estate agency does not want to pay the seller's price, they can choose some reg fee alternative like
Miami-FL-Condo-Sales.com
While all domainers will benefit from increased value placed on domain names as branding tools, the reality is most people place little value on domain names and consider it extortion to have to pay more than $50 for a domain name. So an investor which gets stuck paying premium renewals on virtually unknown extensions is going to very quickly dig their own domaining grave.
