We have had tenants use everything from latex caulk to roofing cement to try to fill nail holes.

This has pluses and minuses.If your property is bulletproof such as no framing - cinder block construction, cement floors, gloss white paint slapped on the walls and a cheap window mount AC, then you are in a prime position to make money with S8. 

.--- Another lawsuit resulted from owner's contractor taking down basement handrail to get supplies down the steps, then they didn't put it back and tenant fell down the stairs.- We also negotiate a reasonable completion date, depending on the Scope Of Work (SOW). --- Who gets all the phone calls and wastes time calming a tenant down because the owner's contractor doesn't show up as scheduled after they took time off from work or a 3 day job takes 3 weeks?

The only situation when the stairs have to be used on the top floor is when going downstairs to the backyard.  

As mentioned before, stairs were broken, floors were moldy, etc. 

Would you sue yourself if you fell down the stairs or found mold in the basement?

At another property with just the sidewalk I let the tenants take care of it, but the liability of these steep stairs makes it too important for it to be haphazard or me having to scold them to shovel and salt the walk and steps.I know in snowy areas people with houses contract plowing for the winter at a flat rate.

Compliance items such as adding smoke detectors, hand rails, fire resistant garage entry-door and new stairs outside.

When it comes to analyzing properties, I’ve developed a specific checklist to make sure the home fits both resident needs and operational goals:Square Footage: Ideally, at least 2,000 sq. ft. to ensure enough living space for residents and staff.No Stairs or Pools: It reduces liability and keeps the home accessible for everyone (this is just my preference).Corner Lots: I love corner lots because they often provide extra parking and outdoor space—both of which are critical for families and visitors.

Also open rail stair can be a nice focal point..
