Any person who possesses any real property does never want to part with it if not really there is a need of it as the real property serves as a security to them. When you are in a need of additional funds and there is no source other than the loan facilities from where you can manage to arrange for the required amount then you opt for a mortgage loan as you can place your property as a guarantee against the loan and get back your asset after the total repayment of the loan has been completed. But sometimes it gets difficult to repay the mortgage loan due to deficiency of funds or you may require more funds to cater your additional expenses.
Refinance mortgage is the facility which is so arranged that it takes over the earlier loan and provides you with a second one with the altered terms and conditions of the previous loan or it is altogether a new loan with new rate of interest. Since refinance mortgage is a secured loan it would enable you to obtain a large amount but you should keep the fact always in your mind that your asset is kept with the lender which has to be released on repayment of the loan. So the amount of loan should be as much as it can be repaid easily...
