I've been building resources and planting seeds on other sides of real estate and I'm smarter and more prepared now. 

Sounds like you want to grow that planted tree you have there in the form of $100k.

Does have trees, plants, , shrubs in the backyard reduce value to the property due to higher maintenance and less usable space compared to same size backyard with just a lawn in it?

For example, updating a light fixture or putting in a ceiling fan can be fairly inexpensive and increase the value of the property at the same time.A simple gesture would be some outdoor plants to provide curb appeal.

They painted one room and even planted a flow bed in the front.

And the qualified property exemption applies even if the you elect to decline bonus depreciation, to claim the special form of bonus depreciation available for specified plants, orelected (for the first tax year ending after Sept. 27, 2017) to claim 50% instead of 100% bonus depreciation.

Anyway, I'd like to plant some roots here.

They planted marijuana in the back yard, this is the one that really made me lose all the sympathy.

I rent to those guys you see working on the large erections of steel at a petrochemical refinery and associated fertilizer plant. 

@Michael Plante I did not change my offer to reflecting the seller to pay for it.
