my friend asked me too look at her mortgage statement. she has paid £10K over the last 12 months but the figure on the statement is £6k higher than at the start of the year. she has no clue what her mortgage rate is or really anything about the mortgage, her STBXH arranged it all at the time and she has just been muddling through since he left. she really ahs no clue about any of it and admits to just binning the statements when they come in. this is the first she looked at and is shocked at what she saw. i also have no clue about mortgages but i guessed that it could be interest. but would there really be £16k in interest over a year on £178k mortgage? also, it says it's interest only so if so, not only has she not even taken anything off the borrowed amount but she isn't even clearing the full interest. can that be right? she's going to ring the mortgage company on monday but i said i'd try to find out if it sounded right.
