There's another category called "prepaids" you'll want to get familiar with as well, which are the taxes and hazard insurance premiums a lender requires to be paid in advance so as to ensure their collateral (your home) isn't go to be a loss if you don't pay the taxes and the Govt comes and takes it away or it burns down in a fire. 

Personally I got burned on a ROTH IRA a few years ago. 

Now, if the lightbulb was out or burned out at the very beginning of the tenancy, I would replace it on my dime.

@Kevin Martin What I believe your lender is referring to is they want to see the full years premium paid in full which is typical of bank mortgage requirements.Bank underwriters don’t like monthly payments on insurance because if you don’t pay the policy lapses and if it burns down with no coverage they think it’s likely you won’t pay them back.

They kept telling me that the wood chips destroyed their landscaping, that the wood chips were causing allergies to their children and burning their lungs, etc.

One day, when I'm done growing a business, have more money than I care to have, less energy, and perhaps a family... sure, I'll keep more than I sell, but I'm not going to buy projects then.

@Cassidy Burns that was an awesome story!

Billy really does need you, since he's 6-36 months away from either burning out entirely, or using the services of someone like you... there is no 3rd possibility. 

Also, if you have extra cash burning a hole in your pocket and no other place to invest it, it might be wise to rehab for a better return.

The college kids who thought they'd get an easy entry-level job at an energy company are recalibrating, but you're not going to see widespread foreclosures or drops in purchase price.
