I’d buy a house with a tree growing inside.

If a property has massive problems that can't be seen from the road, (blocked by trees, carports, etc.) that could be seen if I just got out of the vehicle and did a small look over, then I would rather find it right then and there and not after attempting to contact the owner.In fact, here's a prime example: One of the properties today had an entire collapsed backside and deck that was out of view from the front.

We take care of the shrubs/trees for all of our properties, but the garden beds and lawn care are sometimes done by us and sometimes done by the tenant, depending on what we write into the rental agreement.

.) - I've been trying to get the landlord of the property next door to my rental to cut down the 100 ft maple tree next door that is dead.

I went to the property, found the sewer was crushed by tree roots outside the house and excavated and repaired the sewer pipe in 45 minutes (NO B.S.) and the cost for materials was about $25.

There are a few trees and shrubs in the beds, but for the most part they're just mulched, but eve with the much there are still quite a bit of weeds. 

Our tenants have asked us to get HVAC service, as according to them the system is not as efficient.For context: this is a single family home we are renting out in CA while living in a different state.We did spend almost $10k this year to get pine trees cut down in the backyard, for fire prevention, which is not a cost we had accounted for when determining the monthly rent.We did change the motor of the AC in 2019, and from what I understand AC maintenance is not responsibility of the landlord.The previous tenants, did get HVAC service themselves.What would be a polite and tactful way of getting back to the tenants' ask for HVAC maintenance?

Some sellers have dug up and taken plants (even small trees or bushes) with them."

They were parked on the street and a branch fell from the tree .  

I myself am an avid hunter of white tail deer, and I have a passion for homesteading (think cabin in the woods, hunting, gardens, apple trees, bee keeping, livestock, and no electricity) that is only matched by my passion for real estate.
