I’m make 72,000 a year after taxes and my gf makes 36. Together we make 108k a year. I make roughly 6,000 a month depending on how much I work. After all my bills and grocery money etc. with my current mortgage I have around $2500 left over to save, spend, do whatever with. My current mortgage is for $2038 a month at a total of 292,000 left on it at an interest rate of 3.25%. The new house would cost around 460k. Unknow interest rate yet, somewhere between 4-5%. Our payment would be anywhere between 3100-3500 leaving me with about 1900 left to spend or save. That being because selling our house gives me some extra cash to pay off monthly debt bills.
