There is lis-pendens' in and over the suit schedule property which is the crux of the matter, both parties concerned are in court, the court has however not given any interim order of stay against the land lord from alienating the property to any one else.
In this background,
1. It will continue to be in land lords name and if the landlord has created a charge over the property at the time of raising the home loan, then without the consent of the bank you cannot buy the property.
2. E C reflects that the property is non encumbered.
3. The purchaser has filed the case against the landlord alleging that he is not coming forth and executing the sale deed in his favour, if the court were to direct the landlord to receive the balance sale consideration and execute the sale deed in his favour, then what happens to your agreement and advance payment.
4. As discussed earlier, without the closure of the loan, the landlord cannot execute the sale deed in your favour.
5. Religion is not important in such transactions, it is applicable for every indian.
If it is only the question of money, meet with the earlier purchaser, offer to pay him back his advance, along with interest, take his signature as consenting witness, and then clear off the loan amount, and then pay the balance to the landlord. If this is acceptable to all then enter into an MOU with connected parties without any advance payment to be made now, but once the case is agreed to be withdrawn, then agree to pay the money.
