NRI's Ghaziabad investment dilemma: Sain Vihar

Sain Vihar keeps coming up every time I shortlist something. I'm based in Dubai and looking to invest in a 2BHK or 3BHK in Ghaziabad, maybe for future self-use or rental income. My budget is around ₹70-90L. What's the real ground reality for appreciation in Sain Vihar over the next 3-5 years? I'm worried about legal clarity since I can't do a site inspection myself; any known land disputes or builder issues there? Also, for rental management, how effective are the RWAs and what are typical maintenance charges like? I'd need a property manager, so understanding these hidden costs is crucial. Any experiences would be super helpful.
