House drama

 we have to update the sq footage of our home which now we have to sale at a much lower price, about 100K lesser than what we thought. The city has it at 2600 but two different appraisers have it at 1900....so, now we have to stop buying the new house bc we can no longer afford it at this point. We don't want to get another mortgage bc the whole idea to sell our current home is to get a newer home and no longer have a mortgage. so, we are back to square one looking to find a new home for under 350K....ugh
