You're renting a property in Mumbai for ₹25,000 per month. Here are the key things to know:

• **Payment:** You must pay rent by the 1st of each month. If you're late, you'll be charged ₹1,000 for each day you're late.

• **Security deposit:** You need to pay ₹75,000 upfront as security. This money is hard to get back.

• **Repairs:** You're responsible for fixing everything that breaks, even major structural problems.

• **Leaving early:** If you want to leave before the lease ends, you lose your security deposit.

**Watch out for:** The daily late fees and your responsibility for all repairs are unusual and costly.

• **Interest rate:** 24% per year (very high - normal rates are 10-15%)

• **Late fees:** ₹500 per day if you're late

• **Your gold jewelry:** The lender can take it immediately if you miss payments

• **Total cost:** You'll pay 50% more than you borrowed
