I'm currently renting and thinking of buying a house. Say I make 8k/mo. After rent (1000) and taxes (2000) I'm left with 5k/mo. If I were to get a mortgage at (say) 2500/mo, how much money is actually left over. My understanding is that I would now be paying taxes on only the 5500, so an extra 1300, leaving me with 4200/mo. Not sure how much on top of that I'd have to pay for HOA or whatnot, but I want a good ballpark of the monthly changes to my finances.
Even better would be a mortgage calculator which takes all this into account, so I could play with the numbers a little bit more.
