I bought it about 9 years ago as a primary residence, which keeps my taxes low.

First there is no reason to buy a Townhouse "all cash" instead put 40% down and reap the benefits of an extrenly low rate, No PMI and the option to escrow.

Plus funding is readily available and deals need to mature a few years before profits emerge, so why would a turn key provider not just keep a good rental property.Our inventory is so low in Milwaukee, that sellers don't have a reason to give a discount. 

There is some truth to that, but that rhetoric largely came out of a massively long bull market with historically low rates.

I look at it as what are my other options, where can I earn more BUT and a big but that most ignore, what is the risk profile of the investment?

I think there's going to be a serious thinning out of STRs because of the overall market and interest rates, and people just getting fed up with the platforms, unless one of the newer no/low fee platforms takes off. 

Silicon Valley job growth in tech and manufacturing, low property taxes, and landlord friendly.

That $1400 rent actually makes sense given the low purchase prices.

Flat fee brokerages have been around forever, as low as $295.
