I was a landlord for the guts of a decade. It was pretty much by accident due to a job move I held on to the house in case I ever moved back which in the end I did. So more for personal than financial reasons.
Total return from the house was probably 120%, mainly due to capital gains. But after tax it would be something like 80%. And this was at a time of buoyant house prices and rising rents (got stuck by RPZ rules in the end). I used a management agent which was worth the price but some minor repairs and garden work I just had to do myself. Likewise non-negligible work insurance, tax return, paying tradesmen, etc, and the first set of tenants quit at short notice and I had to scramble for a new batch at a bad point during the pandemic. I'd say it averaged 30 minutes a week, heavily clustered.
Anyway the same period the house got me a 120% return the S&P500 gave a total return of 221%. After deemed disposal I would have made a 130% net return. No question that an ETF would have been a better use of my wealth (and a lot less hassle) than hanging on to the house.
Maybe I'm cherrypicking here, but I'd challenge anyone to pick a moment over the last 30 years where the total return from the S&P500 to date would be less than that from an Irish rental property.
