Loan Mod in Nevada with AHMSI 89129 send me your insights please?

I am working on try to mod my loan since June 2011. They give all kind of excuses. The last one was not accept the signature of a notarized rental contract overseas. They say cannot read the small signature. The tenant has a small humble signature, but its notarized by a serious notary service that mean just like here has to show proper id. What should I do since I am unemployed, divorced, put down 20% of 320K house in 2004 now worth around 102K. The only source of income is that rental overseas, and they still not want to understand that. They want to me to continius to pay 4% rate till riches 5%. It means around 1100 per month + 300 taxes +insurance. Is that fare. What should I do? If I walk way do they will get my condo overseas? Thanks a lot!
