Ayudame con Hipoteca.co

[Inversionistas]

Hi!

I am an international angel investor and want to build a financial internet service offering mortgages and directed to spanish speaking customers around the world.

I have an exceptional opportunity to buy the domain Hipoteca.co for a very moderate price in the coming days. I think the new global domain extension .co suits perfectly for a global operating company but I want you to help me with advise about the keyword "hipoteca". It should be common and instincive in everys spanish speaking country, if possible.

1. Is Hipoteca the only word used for Mortgage in spanish language?

2. If not, what are the other words used?

3. Are there any differences between the distinct spanish speaking countries with respect to the usage of the word hipoteca?

Thanx in advance for your advice,
Inversionista
