Hi
I would think unsecured loan of £10k would be expensive, when your income is £7k per annum.I don't know what a good rate would be, but say it was 16% based on your details. Over 5 years or 60 months, this would be approx £243 per month, which is a good chunk of your income.
I doubt you would want to arrange a secured loan, putting your house on the line. Also you should read articles about unsecured loans and issues if you had difficulty repaying. Apparently some lenders would still look at your assets including your home.
See moneysupermarket guide in link below. Beware that Blackhouse finance loans are vetted by the Unsecured credit company. If Blackhorse will not lend, the Unsecured credit company may take quite awhile to find another loan. You should look at the comments of others about this company on this site and other forums, not happy campers !!! http://www.moneysupermarket.com/loans/
If you have a good relationship with your bank, you may be better getting a smaller more affordable loan with them, if this looks to be at a competitive rate.
