Key West is a unique place with a lot of unique opportunities.

Leaving money on the table is no bueno. 

The nationally renowned Colyton Grammar School is served by school bus in the village and Exeter also has an excellent choice of state schools and league table private schools.

As investors we like to focus on the cash flow but sometimes we have to take a step back and really assess the uniqueness of a situation. 

I agree with @David Krulac - hopefully your property is in one of the 2% RTT areas rather than one of the 4% or 5% RTT areas.The imputed property value used to determine the RTT amount can be found by taking the tax assessed value from the tax assessor, and multiplying (or dividing) by the common leveling ratio that the PA Department of Revenue has posted at their website, for the year and month of the transfer (the values in their table change over time).Once you have that value, and the tax rate for that location, you can figure out how much this screw up cost you ;)

What is the unique selling proposition for this property?  

. - Ask for the cincinnati port authority grant- from whichever lender you use, that grant paid my entire down payment so all I came to the closing table with for a $175k house was $3200 in closing costs - To qualify you must have 700 credit score and not make over $100k.  

We left a lot of money on the table in unpaid rent, but made out just fine.

That said, college students are basically a unique bunch.  

I'm also in the process of building a spec house with a partner in a Texas resort area, which is a first for the both of us.I think I am unique in that I have only ever used commercial loans to buy investment property, which I hold in LLCs.
