If you have language in your lease that allows for entry to complete necessary repairs, I would give them official notice to enter and finish the window install by personally accompanying the contractor. 

I don't think they picked me solely because I was a female or if it even entered into the decision. 

When I see a for sale by owner or I see a building that interests me, I simply knock on the door and ask to speak with the owner. 

Will my new lease be simply a "company name change exercise?"

I'd simply reply that the duct work isn't covered because you didn't touch it.

You're simply co-borrowing money on a property you don't own but want to buy from your co-borrower later? 

Your neighbor can sell his house at any time by entering into a purchase agreement and going into escrow.

Simply put, you're way too big of an expense when they sell (even for reduced commission, as over many deals it adds up) and they would also get the added savings when they purchase either in the form of price discounts or getting the commission.

Generally I tend to stay aware from Now areas simply for this reason.   

@Brock Mogensen  We have anyone we are working with sign one, but we also share with them that at any time they feel we (our team or myself) are not doing a bang up job for them, they can terminate the contract by simply "firing" us.
