Kredit.Guru is cool domain name which will be of interest mainly for German end users - but it is long shot imo, so it might take some time to find correct end user (loans comparison internet portal, maybe big bank or mortgage/loan broker company). The fact that end user will be probably in Germany, means that for outbound sales activities maybe German language will be needed when offering this domain..although the fact is that lot of business people there commands very good English. If sale is done properly, this domain can imo achieve mid XXXX - low XXXXX within next few years.
