Its hard enough if the home was in your name let alone an LLC as your LLC can not get any bank financing.

If you have cash on hand to fund the rehab and want to extract it soon after the project is done, you can use delayed financing.

If she wants to owner finance it that's great but I would want full control. 4.

Does anyone have any creative financing advice or any insights?

The vast majority of these units I purchased using private financing with $0 out of pocket. 

Borrowed money from friends and family to pay cash for the property as the bank would not finance it until it had been remodeled, made livable, and brought up to code.

Most affordable developers will pay more for a given piece of property but will want to lock it up for two years under a financing contingency so that they can go through two rounds in the event their project doesn’t get awarded on their first round.  

I recommend comparing lenders to make sure you get some good terms and financing options for your next investment!

Then connect with some hard money lenders (you can find some here on BP as well as some who are typing this right now) and connect with them to understand their product type, what they like to lend on and requirements.Hard money broker is all numbers game of making relationships and helping those that are looking for financing, it starts out slow but if you get with a few good borrowers and lenders it can be pretty decent money to be made.As an example we paid six figures last year to HM brokers. 

There was a learning curve about investing in Costa Rica and the costs associated with it and financing and everything else.
