One of the best ways to go cheap is to live full time in an RV. Plenty of nice used ones around. No more property tax. You can change neighbors if they annoy you. You can change states easily if they annoy you! Toy hauler RVs are even better. Take your garage with you and your bikes. The govt. doesn't even know where you are. Relatives don't stay long and kids can't move back in with you...no room and bad guest beds. Perfect.
After California you will think everywhere else(except Florida and AZ) is super cheap any way. I would say to try NM but it is getting too crowded already
