I don't like very generic domains (with some exceptions);
For example, take Helicópteros.es
You will use it for what?
A site about Helicópteros? How it will be monetized? Ads of companies who sell helicopteros?
I doubt this...
For me, such domain has a negative value of -10 dollars/year.
-BienesRaíces.es and Empréstito.es: very generic and not very commercial terms.
Again, the same question- you (or the end user) will use it for what?
If you have an answer to this question, thn keep it. If not, just drop it.
I think, so called category killer domains are tempting but not very practical;
Unless you are into hoarding domains, go for domains which can be used as a business, company, a site that sell something(brandable) names.
Rápido.es -this one I like for the above criteria, it can be used for transport business or another:
there are many exaples of businesses using various variations of Rápido in many fields.
https://www.rapido.com/es-es/
But your domain is .es which means somewhat limited market; try to go for .com
Good luck!
