We have four mortgages; our home, a holiday property (we had a caravan and sold it to buy a small house in the area) and we own one rental and we bought my mums house couple of years ago as she got divorced and couldn't afford to buy her husband put (second marriage- not my dad).
Anyways, 3 out of 4 mortgages are up for renewal next year.
We are lucky to be comfortable financially as husband has a good job and I am well paid for part time, but all three increases are likely to have a big impact on us.
We spoke to our financial advisor and he suggested, when it comes to renewal time on our own property, we get around a 2 year fixed term on the best rate we can get, and to keep our payments similar to what they are now, we (for those two years) increase our term in years or go interest only. And then once (hopefully) the market settles we can reduce the term again after the two years is up. May be an option for others too.
It's not ideal, but makes me sleep better knowing we have an option should the interest rates keep rising as they are.
