Long term I think things will shake out. 

Hey Dick, What terms are they offering you?

This could provide funds for an EMD without needing a personal loan.Bridge loans - While not specifically for EMD, bridge loans are a short-term financing option that can help fund a purchase before you have access to longer-term financing or funds from selling another property4.

On top of it, reaching 20% down through principal reduction and appreciation could be a decade out.So you should probably look at the project as a long-term partnership with you co-owning this with your sister for the foreseeable future.But these are great opportunities. 

You are positioned very nicely to build a substantial real estate portfolio for long-term wealth generation and monthly cash flow. 

Additionally, I am willing to live in one of the units for a year.My long-term vision is to buy everyone out and eventually own the property entirely.What are some common deal structures I can explore based on my contributions and end goal?

Also you have to be aware that some of the "wholesale" deals were actually purchased off MLS and just recycled with that marketing term. 

Asking in terms of the neighborhood, schooling systems, etc.

Though if personal use or long term safety are a concern it can make a lot of sense as Disney will always be a market (whereas places like Broken Bow I could see fading from popularity) and unlike many markets there is almost no regulation risk since these properties are built in tourist zones specifically for STR.I own there and manage others so have real world revenue data if you want specifics.

Prepayment penalties- usually 1-5 year terms.
