I have about �49,000 of equity in my house, i want to buy a new car, but cant afford the �450.00 payment for the new car! I can get about �2,500 for my current car so i would look to borrow about �7,000 for my new car! + �2,500 for my current car - my budget is �9,000, My mortgage isnt due to be renewed till Jan 2009. Is there anyway i get get some equity out my house to put towards this new car i am looking for? my current mortgage payment is �350.00, i would prob manage about �400.00 a month! and that's pushing it? does anyone know how to go about this? Any ideas would be very welcome!!! - thanks in anticipation!!! :) cheers!!!
