As long as you have farming experience you’ll know if they’re running your land out of nutrients or not rotating crops correctly.

Well, if they are fully functional on a slab with plumbing, HVAC and electricity, then they are a real asset with value.

Once you have a short list, get an account with each one and run them through the wringer to see how they really function.

I feel like $80k-100k is the cost we were coming to when we considered rebuilding the existing stairwell to the basement to a more functional one along with rehabbing the current rec room to an insulated space.

You are searching for a place to live, that is the primary function. 

If you do purchase a property with a septic tank, you can have it inspected and pumped so you have a baseline that it is functioning correctly if the seller cannot give you any history on it.

I am planning to move into a property manager function in upstate New York.

I mean you can do it but its still not legal if you have a website advertising properties you don't own.. that's the key.. no advertising properties you don't own.. in any form or function..
