The credit Union my primary home mortgage is through keeps all their mortgages on their books so they would probably be more inclined than others to call it.

Looking for a house we could house hack, had an incredibly low interest rate on mortgage and house has increased in value about 42%, an estimated 180k in equity.

@Godsheritage Adeoye when you purchase a property "subject to" the existing mortgage you will then make payments to that mortgage company. 

Hey Joanne, you’re definitely onto something with room rentals.. it can be an excellent strategy for offsetting a hefty mortgage and, in some cases, bringing in higher total rent than a single lease.

My idea to buy a home is to get an 80% LTV 1st mortgage from a bank, take over that mortgage and give the seller a second mortgage for 50% of the 1st mortgage balance because I need some cash to cover the payments, which the amount of cash would be more than the remaining equity in the home.

It may or may not show on a credit report, depends on the servicing and you should have the loan serviced.Failure to include the debt on a future loan application is mortgage fraud, wanna go to jail?

This is my first personal mortgage so I'm trying to learn the game.
