Is it really though?
Rawson takes care of everything for me.
Billing, paying obligations.
Evictions, lawsuits the works.
Its completely hands off.
Sounds like you are batting on a good wicket. In my experience they take a fair cut of the profits though, which is OK when you are in a position to absorb it (+- 5+ years in). The key is to make minimal profit in order to reduce income and inevitable SARS taxation. It needs careful management.
Then there's the (preferred) maintenance contractors who can pull you a new one. Things like charging R1500 -R2000 to replace a tap washer and R3500 - R5000 for a toilet bowl seal. If you are not hands-on, inspecting and making sure of the required maintenance, then you will lose. I am not even talking about small things like plug & light switch replacement, door hinge adjustment and sticky locks.
Another thing is renovations: After 8-10 years, the kitchen, bathrooms and lighting (at the very least) will be dated by contemporary standards and not be up to snuff with the latest and greatest demands of the rental community. This can be costly, and renovation expenses need to be juggled with rental payments, booking factors, and availability.
The first few years are key: Don't make any profits, because SARS will take their cut. Rather declare a loss. 5-10 years, record marginal profits. 10-15 years, do minor renovations, minimal profits again. Last 13 - 18 years, do major renovations, once again minimal profits. All of the time, balance your renovation decisions with perceived market value. It's a mistake putting porcelain tiles / solar electricity into a home in Thembisa, or a pizza oven into a home in Soshanguve. Bryanston / Kyalami perhaps yes, dependent on demographic and demand.
Managing 8+ properties is no joke, rest assured that the landlord will work a full day (and night) sometimes. Agents can assist, but their objectives are not aligned with your available cashflow and long-term objectives. Then there is the inevitable BC/HOA kak, because tenants are humans and after consuming a few Black Labels cause domestic violence, destroy the clubhouse toilets in a hormone-driven sexual orgy, party on top of the floodlights, break / damage others' homes, destroy the guardhouse CCTV screens, drive lightpoles over because they cannot park, and make poor decisions on where they decide to do Number One and Number Two (in the strangest places) on the common property.
Tenants and their kak are a fulltime job.
