I would like to get a wireless internet inside my building.

Is the affiliated operating company the lessee or are the residents the lessees?  

We do not know when it will change.Planning under these conditions is highly problematic and may backfire if you guess wrong.Also, remember that most people in Congress, regardless of party affiliation, are wealthy business people and owners of real estate who are not interested in shooting themselves in the foot.

But 2 days after closing the previous owner tells us she has a contract for both satellite TV and internet for each unit, which we were totally unaware of.

I feel like there are companies you can find on the internet.

The cost of this will vary from board to board, but assume this will cost $1500/year annually in Idaho.View the requirement of affiliating with a broker as a good one. 

I was trying to direct OP to the actual guidelines to discuss with his lender, and any “advice” of mine is only as good as the average internet comment, which is to say not good at all, not an expert in the field.

Also before you do this you'd want to check the landlord tenant handbook and not just take some stranger on the internet's word for it, but that kind of goes without saying.

It sits outside our Z-Wave network so I can get a reading as long as there is internet.

I have no affiliation, FYI.
