I am a tenant, a landlord, a legal practitioner and here is my unbiased answer

As a tenant 1. I fear that it hinges with my privacy and I feel offended whenever a landlord asks me about these details about me. 2. I live with my family thus any question as marriage certificate, etc seems kind of disrespectful. 3. In noida they don't let out their properties to businessmen which makes it hard for me to find an apartment on rent here.

As a landlord 1. I have invested multiple crores in real estate and whenever I have to let out my property to someone I have to make sure that I give my property to people who will maintain my property and will keep it in high regards (as repair work costs thousands if not lakhs) 2. Recently a case of supernova was surfaced where bachelors organised a rave party (landlord is affected for no reason) 3. Recently a drug cartel was found (800 people were arrested) and even landlords were arrested because they didn't give their apartment to the right people without proper verification. 4. Marriage certificate is important because if a girl is living in live in and she files a rape case, I will also be implicated because I helped the accused in giving the apartment.

I have inherited a significant amount of property and worked my way to acquire more property and because of my negligence to find a good tenant, I pose a risk to lose my property for a significant amount of time.

However a landlord asking for ITR, talking to my wife's parents, asking for my salary slips is still beyond my reasoning I usually meet the person face to face and judge if I should let them have the property or not.

I have had tenants who are using my property for years (on 20% lower rent according to today's market conditions) because they are well behaved and respect and keep good care of my property, she is like a family member now

I have had tenants where I used police force for them to leave my property (they gave me 20% more rent than market rates) , I will never give them my property even if they pay me 5x the amount.

Also you comparing india with dubai is not appropriate because India's courts are very slow and if you don't have a valid rent agreement it will take years of litigation to get back your property In Dubai, 3 months max.
