I was glad to hear it was only $191 to fix a drain in the basement.  

I informed the tenant and he explained that when bank returned the money, his other auto pays drained his account so he doesn't have money to pay rent.

I've dealt with that twice with people I served with in the Navy and they were some of the most morale draining people we ever dealt with.

My quote was from State Farm@Jason BottThe quote is for $10,000 in sewer and drain backup and w$500k in liability and $5k in medical coverage with the replacement cost to rebuild at $696,400 for a $300k property. 

. $35, popup drains and come with hoses!

Sounds like a small drain for the frost free feature is clogged 

Check faucets and under sinks for leaks.If you are an over achiever, drain and flush the hot water heaters every year. 

We painted the interior, added backsplash in kitchen, laminate floor in BR's, changed some light fixtures, and faucets.Contractor solved the surface water that plagued the foundation- added french drains, graded exterior, replaced the rotted gutter system, and new vapor barrier to crawl space.

Investing in properties is supposed to complement your income not drain it.   

@Vicki Lau even if a tenant leaves a unit very clean I often still pay about $250 or more to have it professionally cleaned (deep cleaning such as getting the oven and fridge back to like-new condition, carpet steam cleaning, drain clearing, bathroom sanitization, etc).
