I know a guy in Maine who builds high end tree houses for people, let me know if you would like to connect with him. 

We had our ash tree population decimated by the emerald ash borer beetle, which is an invasive species from China, but they are pretty hardy and survive -20F pretty well

Using real trees as the base?

Then I get the prospective clients making 6 figures on their regular job but they're still swapping out doors on kitchen cabinets or fixing toilet guts in the evenings and can't see the forest through the trees yet. 

Welcome .  . be sure to find our next monthly meeting on the 2nd Tuesday of the month, which right now will be October 8th, at the Double Tree in Overland Park. 

I don't want to fork over 50 K into a tree that will rot in a relatively short period of time.  

I do like some Dollar tree conversions from older pharmacy stores in good locations.

This is a garden home and the yard is fenced in with a 10 foot privacy board in board fence The neighbor stated it was making her violently ill and that it is a health hazard for her as it was coming in through her vents and or windowsshe has also been known to harass my last tenant, and sending us text that trees are too close to her home telling us that we need to cut it because there were branches over her skylight and she claims that it was scratching the cover. she called the city when the last tenant had to sell all of her items at an estate sale due to loosing her job and having to move from the property and cited that she was in violation of city ordinances due to not informing the county of an estate sale.

If something obstructs the sewer line like tree roots, and grey water is trapped in the pipes and overflows the lowest point that could be covered.

There should be a law limiting how close a tree(or type of tree) can grow near a property line.
