Educate your tenants and tell them they must move the grill to a safe location.

Ballpark it at $40K to be safe.  

If you invest in solid cash flow and purchase your property at a discount, you will be safe no matter what.

. :-)I did some research and found out that patch of land uses the "safe harbor"approach, rather than the "principles"approach.

"Landlord's Obligations: The role of the landlord in the HCV program is to provide decent, safe, and sanitary housing to a tenant at a reasonable rent.

I would like to think I played a small role in stabilizing the lady's family situation by providing clean, safe housing at a price that was affordable to her when her options were limited. 

Everybody has their own definitions for "safe" but for the most part, the "safer" an area is the less you'll find multifamily rentals (or the more costly they will be).

And some of these apartments are in the ultra safe highly affluent neighborhoods like chelsea, TriBeCa, upper west side. 

However, you want to be safe with their money as well which should mean no more than 80% of ARV. 

Good luck and be safe!
