They even do extra stuff around like the house (repairs and helping with the garden).I haven't raised the rent since they moved in.

we have individual storage lockers for  each apartment, laundry room in every building, private parking lot, and if you count this i just bought them patio furniture and put it out our courtyard and plan on having someone come in to plant a vegetable garden ( we have a couple seniors who miss their garden and alot of our students are vegans)

The building and lease does have a no smoking INDOORS policy.PS: What does 'BID' on the prescription mean?

If they're contiguous lots, you could put in gardens for the tenants, or a yard or play area, but it seems like even then it could be a draw for people to hang out in, and would be a pain to maintain.

They had 3 generations living in that big old home & their veg garden & home made slivovitz was amazing.

She likes to do gardening so she has two garden hoses attached to two outlets. 

But, all you have to do is get a list of handymen, plumber, electrician, gardeners, etc., you can call if there's something that needs fixing.If the market is tight for buyers, it is probably also tight for renters and you could probably get a good tenant in there easily.You just need to be picky when you are screening. 

However now 2 weeks in a row, I have squatters breaking in through windows and kicking in doors.

One of the room mates did mention during the tour that she did but heads with the landlord sometimes because he hired landscapers to tear up their garden/didn't allow gardening, etc.

If you can, stay in doors.
