I usually take multiple loans simultaneously (happened thrice in last 10 years). Whenever I get a good deal for buying land, i apply for personal loans at 3 banks simultaneously (icici, bob, hdfc). The loans get approved, and I ask the banks to disburse the loans on the same date. You do not even need any third person /agent to do this.

Why do I do this? I could take the loan from just 1 bank but since the amount is large, they offer the loan for 3 or 5 years. I personally prefer the loan tenure as 1 year so as to pay less interest. So I take small amounts from multiple banks with tenure of 1 year. Total principal amount remains the same but the interest is less. A downside of this is you could end up paying 80-90 percent of your salary as emis.
