If someone gets their own mortgage, the seller gets paid the balance (after fees associated with the closing) in cash.How exactly does that work? If somebody gets their own mortgage, don't I get monthly payments, or the whole thing at once? What interest would I be paying taxes on here?
If YOU carry the mortgage, then you will be receiving interest payments, and you will pay taxes.
The bottom line is this: If you are asking for answers to such basic questions as the last 2, then you need an estate planner because, again, you know just enough to get this whole thing done wrong, which will cost you money.
