Depending on the size of your deal, you would be looking at a spread of 280-325bps over the 10yr treasury, which is currently at 2.55% (all-in rate +/- 5.5%). You can budget a 10yr term, 30yr AM in your model, and possibly 1-3 years of I/O depending on the quality and location.
Also, if the park easily qualifies for a CMBS loan, there may be a path to a Fannie Mae or Freddie Mac loan.
Let me know if you have anymore questions.
