I think your looking at doing what I was thinking of doing letting the mortgage run and keeping your lump sum for treats /emergencies
Not really “treats/emergencies,” but as part of my retirement pool from which dividends and distribution will fund a 30 yr retirement.
Emergency funds are inviolate and already secured in cash and short term investments, while treats come from bank savings not invested at a brokerage.
Different money has different jobs, and each job usually requires a different account. My personal (American) set up is:
(1) Personal Checking account to cover monthly expenses that are not directly tied to an automatic withdrawal, such as credit cards.
(2) 2 Savings Accounts. One for an emergency fund (at least 6 mos living expenses without any income) and one for “treats” as you called them and my Checking buffer (I have auto overdraft protection using a Savings to Checking transfer).
(3) A 401(k) type account for retirement for self-funded and company-funded monies.
(4) 2 IRAs (ISAs in Britain?). One for myself and one for my wife.
(5) A brokerage account for non-qualified (non-tax-advantaged) investments outside the 401(k) and IRAs.
As you can see, (1) & (2) are basically “living expenses” accounts, while (3) & (4) are “retirement accumulation” accounts.
(5) is a dual purpose account, but mainly for non-qualified retirement funds, as (1) & (2) should cover any ordinary living expenses. Non-normal expenses CAN be used out of the “Emergency fund” if they are not of extraordinary size, to avoid the tax consequences of selling investments. However, discipline is required to both recognize and respond that the reduction in that fund then becomes the primary destination for any excess funds.
Once it’s all initially organized and inflows automated, it is literally a zero work set-up that rarely even needs a tweak.
My retirement account also has a 4% lending facility, where the “interest” is actually paid back to myself because I borrowed from myself! It is a simple, no bank needed, method to finance anything upto $50,000, and I know a few people who even think it’s useful to enable them to stuff a few extra % into their retirement during a downturn!! I think they risk a larger opportunity cost by removing it from their retirement, but many invest it in other things then reduce that investment to get the tax advantages of the retirement account! It’s too convoluted to play with IMHO, but it is a nice way to avoid paying a bank and bank fees if one chooses.
Everyone is different, but really we are all quite the same…we do our best with what we have and hope it leads to a half decent life. The above is how I chose to try to accomplish that. There are myriad other ways, of course.
To bring this full circle, rather than pay off my mortgage, I put the money in (5), where it can do double duty, if required.
