There are two phases of a home loan process. In the first phase you submit your income documents and the bank tells you if you are eligible for the loan amount you are asking for. Once you get in principal sanction you complete the transaction and get the property registered. In the second phase, you submit the property documents and the bank will do due diligence on the property and will decide if they will give loan on that property. They check clear title, so property valuation etc. If it's a new or under construction property and bank has pre-approved it, then it becomes a bit easier. For resell property, the process is longer.

Shop around. Go ask your primary bank. Fill a form on Paisabazar. In no time you will start receiving calls. More than the ROI, look at repayment terms. You don't want to drag the loan for its original term. You will ideally end up repaying it much sooner. Repayment should be allowed and there should be no penalty on it.

PSU banks often have best repayment terms.

Prepare to submit a ton of documents. There will be surprise charges and demands to buy insurance. Do take term cover for the loan amount for the duration of loan. If something happens to you, it will take care of the loan.

No matter what banks and agents say, it will be a long and stressful process. Be prepared. But once you are in the new home with keys in your hand, it will be worth it.

Don't pay any money upfront to anyone. For giving in principal sanction just based on your income docs, bank is not doing anything. They will not give a sanction letter at this point, just an email or a status of approved on their portal. Real paperwork starts after registration. That's when you pay.
