bibas...Yes i work in a securities , insurance and investment industry. but the company i work for is not traded in NYSE, but is one of the biggest company in US, its a fortune 100 company. As far as your internship, it doenst finance helps but that doenst mater, as long as you are intersested in the industry then you can succeed. dont use your OPT for summer intern, the way USCIS works is, if you use your OPT for summer intern, then those days are subtracted from your OPT days, meaning, lets say you work 2 months using your OPT in summer intern, then your OPT which is valid for a yr is lessen to 10 months. Rascal..your question is very vague...but to calcute it mathmatically and answer you, suppose he can atleast put 20% down payment, interest rate 6-7, the most he can afford is for 38000 , monthly payment of 300. like i said your question is very vague, and not practicle for someone making 1000k to buy a house.
