My savings, which are both my present income and future pension, are in two asset-classes;
property and stocks. I'd probably diversify further but gold is for fearers-of-armageddon, and futures and corporate bonds etc are not readily available on the retail market. Plus, the the likes of futures is (IMHO) gambling, which isn't my thing). Plus, I'm much more into 'Invest and forget', than having to micromanage every day or week. Go off to Asia for a month on a family and dive trip?... cool, no need to look at the portfolio (although of course the beast in me nags that I do now and again, just 'to be sure').
I started buying property to rent out in the mid-90s. I bought in an area of west London I knew very well (where I lived) and where I saw something that was well priced [i.e. underpriced IMO], and readily let-able.
There was (or is) an expression in England, and especially London - 'gentrifying'. It describes the process whereby a once down-at-heel area, due to it's affordability and intrinsic geographic and/or architectural merit, becomes popular once again by those (often young) who due to finances have to seek homes at the fringes.
One of my relatives is a pretty serious property wheeler-dealer, so hearing about her got my mind athinking.
The irony was, if say my 1-bed flat was worth £100k and on a £50k mortgage, I could not afford to sell it, and take the equity and buy a 2-bed £150k flat. But, I could remortgage, take out £30k of equity from the 1-bed flat, and use that as the deposits on THREE 2-bed flats to rent, each of which would pay a baseline net 130% of the mortgage. Yes, nutso eh!?
Yes there were some pretty hairy moments at the start. That said I'd analysed everything 20 ways, so I was completely fearless (I'm naturally very cautious, but I tested and overtested everything til the wheels fell off). When ready it was the knight going into battle, just with titanium armour.... 'Nobody is going to touch me today'...
And then, I had a mortgage (from which I initially had nil income) of 13* my gross salary, and that was on top of my own home and mortgage. Pretty sobering, but ya know I was on a proven mission from God... lol.
I still have two of three of those flats, I sold one to fund another even better one. They have increased in value from say £100k each (c. 15 years ago), to say £500k each. And that, self-financing and more, on just 15% down. The biggest downside is dealing with my lettings agent, and dealing with 'f***-wit tenants' and the really bloody stupid stuff they seem capable of doing (don't get me started!!)
The rents typically rise in line with inflation (RPI). When we have a tenant switch-over, the rents are 'reset to market' (at times this is significantly above what a long-term tenant on RPI based rises has been paying).
Since I'm abroad, I use an agent I trust (once burnt, twice shy!) and they deal with everything. That just leaves me to receive their statements and do my accounts.
These days I'm rather inured to some of the crazier s*** that some tenants seem capable of doing, so you know, a tenant asking if they can build a wall through their lounge, or, a tenant getting raided at gunpoint by the fraud squad no longer sends me in paroxysms.
The above was like the 30 year plan that just by
luck reached fruition in about 10.
Now knowing that you shouldn't keep all your eggs in one basket, and being a branded-on-forehead saver not a spender, I had to figure out what to do with the added 'windfall' income I was getting. [Aside: Strange - I went to huge lengths to make this income stream, then when I had it, it was like 'this is weird, what can I do with it?' lol]. So I started building a stock portfolio as I had no need for all the excess money.
There is a financial website called The Motley Fool. It advocates learning and self-investment. 'The Fool is the wisest man in the king's court, and he always outwits the omniscient all-knowing king (aka the banks etc).
So there, is an investment strategy advocated by a writer TMFPyad (I think his actual name is something like Maynard Keynes). He is a moderator there, and he is also a freelance journalist.
The strategy is to buy good quality stocks with sound dividend track records. Not crazy stuff, but a reliable 4-5% p.a. Ultimately the aim is to have a diversified portfolio of say 20 stocks. So right now I've got six figures in that, and since I'm so 'low-maintenance' I at times wonder what to do with all of this.
My inner conflict is based upon an English expression: 'There is no point dying the richest man in the graveyard'.
And just now my wife has stopped in and is asking what and who I am writing to and about

so I explained. And she said 'Yeah, and tell him that that's how you get to buy me nice diamonds too' ironic/:-D
p.s. But it's true

No connection, no self-interest at all. Just I as some regulars will know
very nearly worked in the diamond trade... and as we say in England, this company, IME, are the muts-nuts...

Texas for diamonds. Tokyo (Mikimoto) for pearls.
You'll keep her sweet for life on that diet.
So then later on how do you know when to stop saving, and start enjoying your savings? That is my very current conundrum!
