The issue at the moment is inventory and Lenders are backing away from short term rentals.

@Edward BarrettIf you sell multiple anything in a given year, cars, properties, boats etc the IRS views that as 'dealing' inventory.

Depending on the # of licenses, Costar might range from $300-$450/month per user.  

Rental rates are coming down due to some excess inventory.

In Syracuse, the $800k+ price range is experiencing slightly less competition- I had a large complex just close at a 7-cap.

Depending on what percentage of your excess income you put towards additional principal payments, the difference can range from a small amount to a significantly large amount but keeping the mortgage will never pay less interest nor will you ever have access to more funds. 

That might help rent increases as that inventory burns off.

Here are the other choices in this range: https://www.zillow.com/homedetails/162-Ash-St-Santa-Rosa-Bea...https://www.zillow.com/homedetails/49-Debbie-Ln-Santa-Rosa-B...https://www.zillow.com/homedetails/70-Pointe-Cir-Santa-Rosa-...https://www.zillow.com/homedetails/429-Montigo-Ave-Santa-Rosa-Beach-FL-32459/67187461_zpid/?

I could move that equity into other projects, including properties that would rent for more efficient rates (rentals in the 3/2 to 4/2 2000sf range here tend to go for about $2200-2400/mo).

We are a closed group, not open for anyone wanting to join...Some math is pretty universal though - Let's take a home in your "sweet spot" range - ARV of 700k.
