What rate can I expect? 

With the distance and only have the 1 property I do expect a certain cost of doing business.

@Jacqueline Bruen Whether the LLC has been in operation or not, if you purchase the property through a LLC expect real estate loans to have recourse meaning you will personally guarantee the loans.

However, ideally if we started both with the understanding that collaborations and building the right team in conjunction for planning for our larger future and objectives we'd get to the "freedom" that we are all actually chasing via RE that much faster. 

I reached out to a real estate agent asked the following questions: When I'm done with this project, and after adding 400 square feet to my houseQuestion 1 - What can I expect it to sell for if I decide to sell?

The costs on your vacation rental could be quite high, pushing any increased return far into the future. 

They do not exist that I'm aware of, if it's a purchase - expect LTC. 

In that case, the best option remain is likely to wait for appreciate to raise the property and rent in the future to provide more cash out refinance options or simply find other ways to come up with additional down payments.

I work for a lender, so if you are ever in need of consultation for any future deals I would be more than happy to help. 

Good luck with future deals.
