Its just a small 7x7 structure to place a gas grill. 

I'm thinking a shared free laundry space is one, perhaps a shared grill on an outdoor ground level patio. 

Call hard money lenders and grill them on how they work.Find solid investors that make money. 

I've gone to two so far in different areas (one in philly riverwards - at Johnny Utahs and the other at Fairmount Grille), they've both been really helpful for me if only because of the contacts that I made.

Some things to include are a vacuum cleaner and a grill

Common areas that tenants miss are parts of the range and range hood, the far reaches inside cupboards, ceiling light globes, inside the furnace and hot water heater closets and the heat ducts (take of the heat registers/grilles and see what has dropped into the duct).Read the information in this link:http://www.nolo.com/legal-encyclopedia/new-jersey-...It will give you some insight on how the landlord should have approached the itemization and return of the security deposit in New Jersey.

Long term, I plan to install a couple of air grilles (like a return grill for a furnace or A/C) on both sides of the wall next to the door, and make up a 4" long sheet metal "duct" to join the grilles.

I went up there, and sure enough there were inflatable beds in the rooms, portable refrigerator, barbecue grill, etc.My question is, what do you think is the best way to handle this?

I wouldn't do multifamily over a quad here either.Best of luck and check out Desoto Grill in Kalispell.

We will be installing a playground (lots of families and young children living at complex), common grilling stations / seating areas, and update the club room above the leasing office for an after school study room.
