Depending on the number of jobs and number of new development going on in the area it may just be simple supply and demand.

I recommend that you speak with a real estate accountant to see if you will benefit from a cost segregation first. 

And the reason why your "tale of two halves" will play out as you described.Demand:  This has actually been high almost all along, but rent growth hasn't materialized in response due to high levels of new supply. 

The country simply does not have enough affordable housing units, and the new supply of affordable housing units is not keeping up with new demand.

.), but the bedrooms are regular keys, as @Jonathan C. mentioned for the front door, the unit is set up to send me an email when the batteries are low. i also have another student rental ( 8 rooms, 2 entry, 2 units + utility room) one master key and each bedroom has its own key that will get students in the entry, there unit, and there own bedroom. had a locksmith do that one. cost me a few hundred dollars with keying and supplying the locks ( 13 total ). i like both setups but may look into the landlord locks again for my 3rd student rental i just purchased.

Quote from @Sarah Kensinger: I have never heard of her before but recommend a number of other STR designers.

Typically, co-op's are less valuable than condos for a number of reasons such as supply/demand, lack of investor interest, older units, estate planning issues, financing and board policies. 

@Anthony Saheed I would advise you to be very careful to recommend people to speculate in volatile real estate markets.

I would recommend more photos, especially of bedrooms.

Additionally, the supply of homes for sale is constrained because of this and will be for some time putting upward pressure on prices in most markets.Thinking about renting your house in Seattle would be wise as someone else will pay the mortgage down, and rents and the value of the property will go up over time.
