i hope im making the right choice

[Lilach A.]

hey there, hope you can help me, so after almost a week of going back and forth, we agreed on a price, they asked 420k we agreed on 395k, did the rent calculation and it says after all expenses I will have 500 - 600 left each month .my question is because I'm getting cold feet, is am I paying too much. and I'm not sure the 1-2% rule applies because I am thinking ill get 2900-3000 a month rent. how would I know if I'm making the right choice in this crazy market? thank you.
