Tenants pay for gas and electric, owner pays for water.

Home Warranty: My bathroom sink is clogged and I'm too stupid to know how to pop the water stopper out and clean it. 

It will most likely trigger the due on sale clause in a standard 2nd home mortgage so read the fine print.You can always use a commercial loan instead.

As you get further away from standard real estate practice, the risk is increased by a “legal” risk that your protection may be interpreted quite differently than you expect by a court and that the subtleties of the protection a mortgage or trust deed document provide with established law and court decisions handed down for (in the U.S.) 250+ years is not existent. 

Things such as hot water tanks, carpets had to be replaced in a few years, so I wound up depreciation some items more than once.I sold a rental last year for $430K that originally cost me $70K as an investment property.

There are many ways to invest in real estate, and many different forms of financing, and the "best" type will depend on what you are doing, your funds available, and so on.Here are a few examples:Many investors that buy and hold long term residential properties will use your standard conventional financing (typically 20% down for SFR and 25% down for 2-4 units).

A Bank statement program would do wonders, 10% down minimum is industry standard, if you have a solid credit score,15% down will get you really good terms, however you still need to qualify DTI wise.Best of luck!

As someone who's focused on building out a business for decades to come -- I'm thankful for there being a higher standard we should all be held to. 

In Vancouver 20+ years ago, a bunch of condos were built and they were not built properly and had to have massive repairs done due to water damage on the outside (we called them leaky condos). 

But something just did not add up with those guys ( and they were AZ based and slick as all get out) But to easy to approve me just send 10k for due diligence. only somewhat related but BiggerPockets really needs to acknowledge a new category of lender that falls in the Non-QM space (any mortgage thats not qualifying under the Agency QM rules - including DSCR lenders but also many established non-bank lenders that focus on pretty standard mortgage products that are part of the established Secondary Market and Finance Infastructure).
