Funds from India

My father passed away last year without a will and my mother is consolidating our properties and giving our share.
1) What are the options are there to get it to US?
2) How much will be taxable?
3) The buyer of the property has a daughter in US and the buyer has discussed to transfer certain percentage of the money to me in US.

Which is the safest and wise option to go for to get the funds to US? We are talking about somewhere around $300,000. That is the reason I want it to be clean according to books, as there will be a lot of black money in a property sale in India.

Has anyone got fund from India to set up a business or to buy a home? Please share your experience or your knowledge on how to proceed further. Thanks
