How Much Home Loan Can I Afford? FOIR, LTV & Eligibility Math in India

Home loan affordability in India is determined by two regulatory benchmarks: your Fixed Obligation to Income Ratio (FOIR), which caps your monthly debt servicing capacity at 40% to 50% of net monthly income, and the Loan-to-Value (LTV) ratio, which caps lender financing at 75% to 90% of registered property value.

How Much Should You Invest Every Month? 50/30/20 Rule, SIP Math & Frameworks in India
