Worst Investment ever!

I own an apartment bought as a longterm investment with the idea to build my portfolio. I think the research done by iGrow is too optomistic and clearly terribly researched. The apartment I bought in Pomona was set to be central to the Aerotropolis development around OR Tambo and that by all indications its a solid investment. I trusted their research but struggled for more than a year to get a tenant because there were just too many apartments. Then when I got my first tenants they ecperienced waterleaks from the top floor. When discovered that its the developers responsitbility I was told that the Developer has a 6-7 month cool of period but after that it becomes the owners responsibility. I would have thought that the managing agents would have done their due diligence and declare this waterleak, but it almost felt they were playing in the hand of the developer. I have had numerous repairs done because not all owners take the same responsibility. They have changed managing agents and the apartment blocks manangement has fallen into disarray, causing all kinds of ******** issues, breakdown in services etc. The aparments are now so unatractive that I can't even sell the unit. With interest rate hikes and Levy increase with over a thousand rand this apartment has gone from R1600 shortfall to a projected breakeven at 3 years to a R4000 shortfall 5 years later. If you write to them on their info email address you get no response. In my opinion do your own homework buy your own property and don't use these clowns. Just another scheme abusing the uninformed.
