Well since we don't know your numbers we have to start somewhere, 50% rule is as good as any. 10% property management5%-10% maintenance/gardening/repairs10% cap-ex holdback7% vacancy Property TaxInsurance Utilities (electric might be separately metered but it's rare for water)Trash (sometimes it's pass-through, sometimes you're paying a dumpster fee for commercial)You can always put your head in the sand and think maintenance costs, vacancy, and cap-ex won't catch up with you.

For example, your gardening bill is likely less per door with 40 units as opposed to 4.

What are the costs for gardening (you'll be paying for that yourself now)?

I do have raised garden beds which I do assign tenants should they feel the need to grow veggies (no Marijuana growing, Colorado folks, lol). 

Try snaking the vent pipe and pouring hot water down it or sticking a garden hose in it.

I hired and paid out of pocket for bi-weekly gardener so that this would not happen.

I trim them back to the property line on my side so sunlight can get to my garden.  

Lots of opportunity to make some money especially in Palm Beach Gardens area.

Now my question  is , should  I let the tent have the option  to upkeep  the lawn or hire a gardener and add extra fees or eat It up from the $2100 or $2300 payment?
