Quote from @Miguel Del Mazo: “Don’t put all your eggs in one basket” is all wrong.

In my area, Boise, ID:$500-$750/tree demo$50.00/lf - 6” Ductile Iron Water Line, 5ft Bury, Standard Soil, Excavation, Bedding, and Backfilling Included$2.50/sf 3” HMA Road Paving

We don’t know any PMCs to recommend in the area mentioned, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

Again, don't get me wrong, cutting and pasting obvious info may help someone, but I think it just jams up the forums.

By installing our own, we remove the wear and tear and damage the tenants do by moving W/Ds in and out and hooking them up wrong (which is common) and using cheap components that cause leaks and destroy floors and walls.

Definitely go the legal route here, don't rent out the basement unless you have the OK from the relevant authorities--it's regulated for a reason (fire safety, carbon monoxide poisoning, etc.) and your insurance will not have your back if something goes wrong.

Right or wrong I am of the mentality: Ready, Fire, Aim.

Think of the worst case scenarios of what can go wrong and are you ready to handle that.See if you can buy time. 

Taking notes and asking questions only got me deeper in the weeds as if I was asking the wrong question. 

If I'm wrong I'm sure someone will correct me.
