There is a LOT that needs to be fixed/adjusted as things have not been correct for a while.

The average 30-year fixed-rate mortgage rate jumped 27 points from 6.26 percent to 6.53 percent on Friday"I guess I go back to buying properties with zero down, taking over 3% mortgages. 

You need to be looking to do some fix and flips and make some short term money.
