Ya the tax benefits seem pretty straightforward, it sounds like Treasury still needs to provide guidelines on funds and how they get certified (or something along those lines).

Second is if you have a problem with that room resulting in a lawsuit then I bet they look to see if the room was up to code, say like an a electrical fire.

Any pro's or cons on this or general advice in regards to this line of thought for purchasing a home?

If you have done some work lining up multiple companies you may be able to leverage the competition to get something like this reduced. 90 days is a long time in the rental game.

My question was more along the lines of specifics and preferences.

If they let you go on leaving your wheelie bins out for 3 days, leaving construction debris on your lot, letting your grass grow or parking unregistered cars (all violations in our HOA) and then I come along and add a garage to my property that encroaches on the property line (but still within city code-this is Colorado now) and the HOA tries to stop me they may well be SOL.

travel, legal fees, license, accounting fees, office supplies...this could included in your property management expense...just adding more line items. 

There are a lot of roots in the line again since 12/31/16 when you had it dug up and pumped. 

Its behind a tree line and stuff so my renters don't even know it exists.A neighbor expressed concern that they would like it to look nicer and expressed interest in this land as a long term lease.

I thought I had a line on a property manager but I am not happy with the responses I am getting so I am continuing to look.
