Our portfolio averages $386/unit for water and sewer, but can be as high as $700 in unfriendly municipalities.

If it's the landlord's responsibility, what are the average costs?

Maybe your house hasn't been on the market that long, or longer than average for the neighborhood..in which case if it's priced correctly, it will probably sell at some point.

As our properties, on average, with purchase and flip come out to around 100k.

I can't speak to your valuation, but something pretty drastic would have to happen for the average house in St Matthews to not appreciate at least 3-5% per year over the next few years.  

In addition, a breakdown of the number of SFRs, Townhouses, and Condos, with corresponding ADOM (Average Days On Market), and Median Sales Price, for each municipality.

April 1997 was the last time the average 30 year was over 8%....Im pretty sure there were some investors around then.I also agree that there isnt a compelling reason to go with a 5/1 arm when we are very close to the lowest historical rates on record.

Looking for advice on rental rates, average/expected returns in this area and also anyone who might be interested in partnering or acquiring either of these contracts from me.

If you are familiar with these areas (above) ...what are average sale prices for homes that are 4 bedrooms, and at least 2000 square feet (fully updated)?

When Rent per sqft is $2+, average house cost $600k and physical vacancy is sub 3% (city-wide!)
