cash plus equity

trying to figure out what mortgage repayments would be. Huge difference between tsb calculator and mortgages.ie. Differences of 9 /10 k in amount needed, works out at approx 80e per month, big difference.
purchase price of new house 640k sale value of current property 575k
Looking to put 50k to sale value thus bringing down mortgage required. but as I say difference of 10k in what that mortgage would be. Help??

I don't really understand your question but I suspect that Karl Jeacle's mortgage calculator might be of interest to you. Read the instructions before using it if it's not obvious to you. Bear in mind that it does not take account or owner occupier mortgage interest relief so actual repayments may be slightly lower in practice. I suspect that the calculators on lenders' websites may only return indicative results.
