36 years. What ratio should I have me assets?

Stocks/Bonds
Property
Cash

Remember seeing a guneral guide somewhere but cant find it now.

Is 25% too much for a single fund even if it's a its a pretty low risk one?

It all depends on your attitude to risk.

IMO you may as well put as much money into your own property as possible – pay of your mortgage. Though if you have a low rate at the moment maybe not bother – I get a better return from my savings account than my mortgage costs me at these days.

Have at least enough cash for unforeseen events – a few months of expenditure I suppose.

Stock market is a funny place these days – Some suggest over-bought at the moment so maybe not a place for a large %age of wealth.

I say no point having 25% in one fund as there's quite a few worth looking at – assuming you're not looking at FTSE tacker anyway.

This site has some excellent research info on funds:

Thanks. I find the management side of multiple funds very challenging so was hoping to just stick it into one well diversified low riskish one. Find it hard to keep track of my ISAS from year to year. Maybe a wall chart is required.
