I have a tenant that I have realized is Bipolar and has some serious mood swings and gets very negative verbally attacking me.She has one of my more challenging units that is street level, with all the living room windows right out on to the sidewalk with no setback/yard.

In cul de sacs, I've seen creative parking-rather than how one normally parks parallel to the sidewalk, angle parking like spokes on a wheel. 

Last winter we had so much feces flowing down the driveway I thought it was walking down a CA sidewalk. 

@Nick Thurston Check with the city or county to determine if the plans will get approved as is and what is required for all approvals and the time frame, Ask if you have to install curb, gutter, sidewalks, street signs, street lighting or any other special requirements.Are there any specific street design requirements, DOT requirements, permits or traffic studies.DWQ, Army Corp or any other environmental requirements or permits.General permit fees, proffers, water/sewer tap fees and the process of setting taps and connecting.

As long as the trailer is parked in the driveway and not blocking the sidewalk, leave it. 

There could possibly be specific wording within that prevents assigning the responsibility for main sidewalk clearing. 

I worked hard to keep my place looking nice, but they nit-picked about my property the whole time that we were working on it, when an owner-occupied across the street was horrible (lawn not mowed, high weeds, not shoveling the sidewalk, etc).   

., a sidewalk) shouldn't create any liability on your part, although you'll want to make sure your insurance will defend you when you get sued (the lawyer's motto is "sue everyone in sight'), but a dog getting onto your property might create liability for failure to take reasonable efforts to prevent the danger.

., I just had to pay to have a huge tree limb cut up and removed from one of my properties after a storm took it down and it was blocking the sidewalk).Even at $0 break even cash flow such a risk is still there.Maybe the alternative is if you plan to only own the negative cash flowing property for a short time period, like one year, and then flip it.

The location is great it is a unique street that actually has no street only alley ways to the homes and front of the houses is a large courtyard with sidewalk next to the local night scene.The other way to do this flip, the house is in good shape could do bare minimums redo the bathroom and kitchen and simple cosmetics items.
