I took on property management as a business for a couple of years for friends and family, now I only manage my own properties, at a distance in London.
A few rules:
1. Tenants are not your friends, do not be lenient
2. Do EVERYTHING by the book, you will get black mailed, I have, it's not pleasant, but fortunately I was doing everything according to the legislation and all the many electrical, gas safety etc... checks were done
3. Do expect to be called for repairs, if you do not understand properties, you will be completely taken advantage of by trades people
4. Do not let the agency manage problems, they add their fees to the trades people you could have called yourself
5. Do not under any circumstances lower your vetting standards. If the tenant is border line in what they can pay, do not take them. Pass on a tenant and have the property empty rather than take a problem tenant
Now this is for the UK where it's easier to evict tenants. Here depending on the cantons it can be a real hell to get rid of someone. Vet those people like you would vet your daughter's future husband.
I have made money from property and I am very happy I got on this journey, but then I started buying when rates were 0% and money was free. Will it be the same for the next decade?
There are discussions of what bonds to buy between the person suggesting you this on this thread and myself. Plenty of good advice to take and yes bonds are more interesting at the moment in my opinion. If you want capital appreciation without the hassle buy stocks, but similar to property, with the end of easy money it's not that straight forward, especially in Switzerland where the vast majority of stocks are trading at a HUGE premium vs. their global peers, it's been like that for a very long time due to the limited amount of investments in Chocolate land, but does not bring me much comfort - I for one at the moment (year 2023) only buy properties that need completely to be redone and get my value from sweat equity, passive income for properties not so sure.
