@Brett Henricks - I attended a large DST provider's conference last week, and asked around about Crew to other Investment Advisors...nothing remotely positive was said.

If your willing to do so, you can live in the casita and then rent out the main home and have your tenant pay the majority/all of the mortgage (depending on what type of deal you find obviously). 

have you considered bringing in an equity partner to provide a loan?

Without knowing stuff like this, all the answers provided are meaningless. 

thanks for the guidance @Kaushik Sarkar Since it's development it will take longer to get to the exit. 3 years could be right depending on the market, if the project requires entitlements, how long it takes for permits, no major utility obstacles, etc.

An existing duplex provides immediate rental income and proven market comparables, reducing risk.

Do they provide exclusive leads, or are they shared among multiple investors?

I have a client in ATL that knows STR very well and could provide some resources if needed.

A CPA who specializes in partnership issues can also likely talk through these issues with you.3) Depending on the size of the deal - Keep It Simple - the number of really complex agreements that come across my desk for a $500k property is crazy, and it ends up costing as much to do those tax returns as a comparable $5m deal

If the cash-out refinance option isn’t providing enough liquidity, you could also consider a hard money loan, though these tend to come with higher interest rates and shorter terms.
