Here are Barbara’s picks: Big backyard trendsLess lawnLow-maintenance vegetation saves on upkeep and time.

For our single family homes, we hold the tenant responsible for the upkeep of the lawn (mowing, edging, weed control), flower beds, vegetable gardens, but we maintain the shrubs and trees.

The tour of the property suggests that they are good tenants - the place is in great shape, units are very clean and there is even a vegetable garden in the yard that the tenants maintain.

Annual fireworks location for $5,000 to $15,000, food truck parking for $300 per day, parking for the next door mechanic, rent to vegetable or Xmas tree or pumpkin stand annually.  

My current 2-week experiment is to get my son to eat his vegetables!

That would be a little more money, but more versatility.

Mostly not maintaining it-not cleaning the filters, if it is an AC unit outside or a heat pump-letting vegetation grow next to it, putting stuff too close to the unit.

There are over 120 grows less than 5 miles from my house (based on a 2011 Denver Post Article on "medical marijuana" before it became legal for recreational use).The grows are located in 5,000 - 10,000 sq ft warehouses or in former nursery locations (as is the case of Dardano's Nursery where I used to buy my vegetable plant starts in the Spring).  

After i bought the place i turned a portion of the basement into a studio apartment to use as an Airbnb, i intentionally designed the space to be versatile, the area can be used as a stand alone apartment with its own entrance, parking, full kitchen, bathroom and laundry or you could open up door in the hallway to use the space as a large entertainment area. 

May I ask do you niche down in investing strategies also or do you keep yourself versatile?
