Tata Arabella Sohna: Are hidden costs killing ROI?

Been tracking Sohna for two years now, and finally pulled the trigger on Tata Arabella last year. Honestly, as someone who works in real estate, you'd think I'd be immune to builder tactics, but the actual total cost post-possession is just brutal. Brochure mein they show one figure, but then maintenance, society charges, some weird 'upgrade' fees... it all adds up. My projected capital appreciation from the initial price-trend looks good on paper, but yeh sab extra costs are seriously eating into the actual ROI. RERA filings mein bhi these subtle charges sometimes don't get highlighted enough, making it hard to compare apples to apples. Kya sirf main hi hoon jo yeh feel kar raha hai? Is the true value for a completed project like Arabella really justified after all these hidden outgoings? How are others managing their exit strategy with these unexpected costs?
