1. It will be difficult for selling the property of the deceased without a Letters of Administration being obtained from Court
2. under the petition for grant of letters of administration the court will appoint an administrator who can then deal with the property of the deceased with the permission of the court
3. any one of you can become the administrator
4. any prospective buyer will be convinced to buy the property if he has to deal with the administrator who is legally authorised to deal with the property of the deceased
5. many buyers avoid buying a property which is standing in the name of a person who has already passed away and thus the buyer would have to deal with the persons who claim to be the deceased person's legal heirs. a stranger buyer will not know how many and who all are the legal heirs of the deceased. therefore buyers prefer to from the administrator
6. so it all depends on the prospective buyer. if he is satisfied with the fact that you all are the only legal heirs of the deceased and that all are consenting for the sale, then he may proceed to buy without insisting for letters of administration
7. for the time being you can execute a power of attorney in favour of some trusted person who will execute the sale of the property on behalf of you all
8. but please keep in mind that this will be a double whammy for the buyer since now he would be dealing with some person who claims to be the authorised constituted attorney of you people and thus the buyer would not have seen you all personally. so just put yourself in the buyer's shoes and think, would you buy such a property which is being sold by a constituted attorney of the legal heirs of the original owner. it would obviously raise many concerns in the minds of the buyer
9. if you do not wish to obtain the letters of administration from the court then you can proceed to sign a power of attorney with power to sell in favour of a trusted person and see to it that you have this power of attorney duly registered. this will give some weightage and credence to the power of attorney
10. your attorney can receive the sale consideration on your behalf and then remit the same to you through banking channels
11. since the property is in India, you will have to comply with indian tax laws and would be liable to pay capital gains tax on the sale price received
