my husband's view is "invest 1/3, pay down debt with 1/3, and fritter away 1/3" (his Dad told him this is sensible and what he did over the years!)
Solid advice for someone in their 20's and early 30's before the serious commitments kick in. Think it may not be as relevant now, but depends on what you call fritter away
Fritter Away 1/3 - Personally I would use this to do an experience with the kids that they will remember forever - so maybe a Lapland trip to see Santa, Orlando when they are a little older, safari in Africa (again a little older) etc. Given the kids ages, and your income level, I would seriously consider a trip to Lapland next Christmas and go back then again in maybe 4-5 years again depending on when the magic ends. I can also strongly recommend an extended holiday to Martinhal in Sagres (Portugal) - the best adult friendly holiday location around (kids are the main guests here, adults are tolerated).
While you are at it, treat yourselves to a nice weekend break in the Cliff House in Ardmore or Monart
Pay down debt with 1/3 - no arguments on that. Pay the 3.1% debt first
Invest 1/3 - I agree with another poster here regarding investing outside a pension vehicle. I have just had to hand over 41% tax on some EFT profits I made last year + cover the same for next year's preliminary tax bill. I ended up making a pension contribution instead to eliminate the tax bill. Given the risks involved in investing, the tax is simply too high at the moment and the reward simply does not offset the risk in my view. Deposits make no interest (lose real value against inflation).
You would have to make greater than 5% guaranteed to beat your 3.1% saving net against the mortgage. I am not sure anywhere that can provide you those returns in the short term.
Is it sensible to have a holiday home while you still have a €700k mortgage on your PDH?
It depends on how much use you get out of it, both now and in the future. How often do you get to stay there and is it 'good for the soul'? How much of a hassle is it to run/maintain and do you believe it is giving you 'value'. A holiday home is only as good as the time you spend in it
I know people who have an apartment in the Cape Verde Islands - they have been there twice in 12 years.
I know people who have an apartment in Spain - they are there at least once every month for a long weekend.
I also know people who have a place in Ireland and they spend nearly 100 days a year there.
If you are not using it yourself for holidays, its a property investment and think you may be over leveraged here.
The de-risking you talk about Sarenco makes sense, but we're also conscious that we could try and repay the main mortgage early and die in the meantime!
Same applied with having 100k in the bank and passing away. At least the state will be happy with the inheritance taxes they receive
There is a balance to be had between a decent quality of life and living like a miser to pay down your mortgage early. I don't think many on here will suggest the latter (although some will), but I do believe you have scope to cut back on the household expenses a bit and clear the mortgage by 60
