My thoughts -- There's a ton of stuff you "could" do; whether or not you "should" do it will depend on some market factors.Mainly, will more curb appeal elevate rents to a level that they will create a positive ROI? 

It breaks it down by building type (elevator, low rise, garden) and by property age.

Corey,Surprisingly, alot of my investors have literally come from the elevator pitch.

Some properties require elevation certificates and other permits.

Electricians, Plumbers and Elevator repair all require apprenticeship. 

As an introvert, I've learned to prepare my elevator pitch ahead of time.

The stats are: -5 stories totaling 20,000 square feet above ground, plus a full basement which is partial commercial space and partial tenant storage/utilities-First floor commercial space is around 2300 square feet with an additional 1500 in the basement, 12' ceilings in the first floor-14 residential units above, most have private balconies or decks, elevator, bike storage, mail room.

Also check to see if theirs a elevation certificate if not get one.

I’ll see about determining the elevation of the house.  

You may want to stay at the lower elevations (such as the Grand Junction - Montrose corridor) due to average temps and growing seasons.
