<prompt> Human: Heres my situation. Im 21 and I just got my first-ever full-time job yay!. I had a job before making about 2000 a month net most Ive ever made and am planning on keeping the gig part-time making 1000mo once my new job starts. I have a unique family situation where I live with a parent who makes negligible money while also taking care of their ailing mother. My parent has supported me my whole life and I have lived almost rent free for a long time. For the last year, I have been paying 1,400 a month to my parent to help with the mortgage but have also had some relatively high medical expenses of almost 5K since the start of the year. Now that I have a new job that pays more than my parent makes, they want me to start chipping in.While Im completely fine with contributing for living expenses, my parent is suggesting that I should be paying over 2,000 a month to go for mortgage payments. I want to help out as much as I can, but is that too much? I want to save money for graduate school and for eventually purchasing rental properties. Here is a break-down of my salary and expenses:Monthly Salary from new job4400 Estimated total take-home3500 1000Personal expenses300Remaining4200I have 4K in an emergency fund, 5K in a Roth IRA, and have 0 in debt. So I need some advice.Is 2,000 a month reasonable considering I havent had to pay for much up until now? I am assuming my parent will also be putting in 2,000mo until the 90K mortgage is paid offShould I keep trying to max out my Roth? Should I grow my emergency fund more?Also, any tips on not getting too money happy once I start making a real salary? Thank you in advance! EDIT: The option to move out does not exist for me. I am with my parent the primary caretaker for my grandmother. The mortgage is only 1,200mo but my parent insists they need to pay it down as fast as possible.  <response>: Find your own place and move out. If they cant afford their own home, they need to downsize. You leaving will prove that to them. Plus, Im assuming your name isnt on the mortgage, so this has ABSOLUTELY ZERO benefit for you financially in the long run. All youll be doing is paying off your parents home.Do not let them guilt you into this or let the fact that they are family screw you over financially. You can pay a lower rent for a nice place on your own and keep the extra to throw at retirement, emergencies, or saving for a home.
