We signed a contract to have our home built about two weeks ago. We still have leeway on the design etc. Our current mortgage payment including an auto loan is about 30% of takehome pay. With new mortgage there will be no auto loans or any other debt, but the mortgage will be 40% of takehome pay. However, we are still thinking about all the extra money we would have to spend on other things or save if we stay in our current home. Things won't be tight in the new home, but we will have to budget more. Is it normal to have second thoughts after signing a contract for a more expensive home. Who has gone through this?
