I believe in June Fannie/Freddie changed the 10% ownership to 20%.  

I've run into deals where things keep changing and I usually bail. 400K is a sizable purchase and it seems that neither you or the seller are completely ready to make this happen smoothly in a short period of time.

I know we have no right to change the terms of the lease (esp rent) until it expires. 

You have to be ultra careful because with this length of time holding the property a lot of things can go wrong and the market can change temporarily for the worst due to weather, holidays spike in interest rates, sudden oversupply etc...

I had hot water tanks changed.

Also, most window companies change their designs and stop making replacement parts on a regular basis.

This will prevent anyone from changing their mind.

In it we say if we do not hear from anyone in 5 days we will assume the property is vacant and change the locks.
