These are, arguably, far more rational than the Fannie/Freddie stuff. 

But only if the total square footage allows for that change to still make for rational, comfortable living.

You need to avoid the shiny objects so to speak, and focus on your goal, with a rational mindset. 

Are you going to rationalize a bad property into a good one...just so you can smile and say, "I got my 90 day goal"?

So don't rationalize spending $2000 on granite because it lasts a long time.As you said, the counter tops will not increase the rent.

That's just rationalizing a bad deal.

Keep a close eye on your debt to income ration and you should be fine.

If things get REALLY bad, then yes, things like rationing, inability to water lawns/gardens, etc. may cause demand problems in those markets. 

The rational is you are using energy that is being created by you car's alternator, so the gas you put in your car cost money, factor in your MPG and then subtract the amount you saved charging your phone in your car....and gas is not really that expensive

This advice definitely helps with my rationality because I seem to already want to be back in Idaho.
