My only major failures are from water, and the newest version has a 24 hr leak resistance.

I also love it when I don't receive phone calls from my property manager about leaking roofs, vacancies, or broken HVAC units. 

There will be evictions late payments leaks fires shootings drugs vandalism and tenant conflicts all the time .

I really like doing owner finance & mobile home parks these days.My most stressful experiences involved picking an occasional poor roomate, getting a call while traveling about a water leak that was my responsibility not the city’s or having to move out & rent the place to law students & other long term tenants & manage all that without professional property management.

A lot of roofers are still using modified bitumin, but there are better roofing materials that can withstand "ponding" without leaking.

Then he asks, "did it leak downstairs".

@Trecia Benjamin - I apologize my iPhone autocorrected your name to Trevor and I didn’t notice it.  

Preventative maintenance is the key - keep the house painted, replace the hot water heater before it rusts out, replace the roof when it's old, not when it starts to leak.

I tell you what sucks …termite damage, structure problems, leaking roof, plumbing problems (in the walls – Hoa responsibility), leaking boiler, burnt furnace, cracks in the walls due to house settling and many other house relates problems, that’s what make your PnL go upside down when you lease house.

you need to check with the city if that porch had a permit pulledYou have no idea about the plumbing situation or electricity (you spot rat droppings ..you wires might be gone)…are the pipes sloping correctly, do they drain, non-visible leaks does not mean that you are ok, maybe it is a good idea to either perform a compression test (if part of the plumbing is missing and you really want to save those old galvanized pipes) or snake a camera into the drain to look for the roots on the way.
