There is no right and wrong answer to this question but I think you have the basis for a good strategy in the replies to date, i.e.:
1. Don't rush into anything and do your research on anything you may think of buying into
2. Get as a high paying an deposit interest account as possible while doing so
3. Observe the old adage 1/3 of your money in equity, 1/3 in property and 1/3 in cash and you can't go too far wrong
4. Be fees and indirect cost allergic, identify them in any proposal and negotiate them down or walk away
5. Study what Mark***** posted above re equities, that shows to me that even in a long term strategy timing still matters a fair bit. If I were you I'd buy ETFs by sector when you think their finished declining and I'd aim at investing in only 1 every 3 months i.e. a drip feed investment strategy, so that you are not trying to time the market so much (that's for pros)
6. So you might end up with an investment strategy something like this:
330K in high paying deposit account
330k in equities e.g. 110K in iseq 20 ETF, 110 in food company ETF, 110 in renewables ETF, as examples
333K in property: Ireland still sucks at the mo at it was hyperinflated by bubble, so maybe 150K in 2 syndicated funds or else overseas property direct (tho I'd avoid that if I were you cos of hassle)
Lastly, since ye are farmers and general property is so weak close to home at the mo, you could consider investing in something that you know e.g. agri tourism project (neighbours B&B, guesthouse, etc), Forestry, or Environmental reps based investment. I give this advice without knowing what returns any of these may give except that a general good principle when investing is to try to stick to what you know something about and do your research on that.
PM me if you have any other queries, I am a private investor like yourself and have no other agenda. I would be very keen to learn more re agricultural based investment proposals currently.
