But what do seasoned investors do with none real estate debt?

Seasoned investors are going to look at a retail property or other assets classes and as part of DD look at what is reasonable as a history for a property and how to validate the credibility of rents and others components of a lease.

Personally, seasonal income worries me but you may have some luck picking something up in Kissimee area and renting it out to a Disney employee

Is there a military base, corporate offices, vacation destination or anything else in your area that you think would help bolster your bookings, especially in off season? 

I’m seasoned in the construction industry and a general contractor license is in my not too distant future.

Depends on the lender, some will want the property to season for 6 months to 1 year before they will do a refi.

A refinance might not be feasible as most lenders will treat it as a seasoned refinance and leverage is generally lower with seasoned refinances. 

These can be very helpful for people new to the industry and seasoned pros alike.

The main ones were low barrier to entry, great metrics, and encouragement from other seasoned local investors. 

During peak it is easy with my PM buying all supplies ect.. but off season and shoulders we use it every other weekend, we are most of the time using the supplies and the off season guests, Cleaning, toiletries, coffee, etc..
