Rights as a Guarantor for a Home Loan

Hi there , i would like to know if a Guarantor is safeguarded in any way in a Home loan default case . I am a guarantor for my brothers home loan who hasnt been paying the emis from the past 3 years . In this 3 years i have paid more than 4 lakhs towards his emis and have also paid the house maintenance and other bills . I want to save up for my future but all my savings are being poured in paying his emis . The bank calls me after 2 - 3 months and asks me to pay up as he has defaulted or to face legal actions . The bank said that they will send legal notice to my work place along with publishing it in papers . I asked the bank to transfer the house in my name and the loan but it denied . Also since my credit score has been affected coz of this no other bank is willing to take a transferred loan . I can sell the house but it will take 6 or more months till i find a buyer and i still have to pay more pending emis . Is there a way around it .Thanks and Regards.
