Owning your own home

Working out all our mortgage stuff over a cuppa today and it more than likely looks we are going to go with a 30 year term fixed for the first 5 years.

Then begin to over pay after 18 months as most of the money will be going in to decorate the house. I'd like to think we'll have it done in 18 months.

At least £100 over pay pcm lowers the mortgage down to 23 years! These figures are crazy when you work them out. At least that way we haven't got all our eggs in 1 basket.

Is there an easy way to calculate capital cleared on a mortgage over the 5 year fixed? Say the difference between a 20 and 30 year term?

I hope that when we go to remortgage in 5 years we'll be looking at a much lower LTV this way too.

I always use the MSE overpayment calculator - you can put no overpayment in and it will show you where you will be in 5 years...
