I know people sell occupied rentals but I don't really want to discount it and for the price that I'd list it I'm not sure it would be an attractive investment for someone else.

Alternatively, you sell them on the opportunity, and ask if they are willing to provide you with proof of funds as you are looking for deals.  

To summarize, investors choose syndication over alternative investments due to :Lower risk due to experienced teamAccess to larger deals previously unattainableLack of time to manage a deal personallyAccess to large depreciation tax benefits due to cost segregation studiesI think these are some of the more popular reasons I hear.

Alternatively could I go through a HML?

if I'm on the right track are there any good alternatives to boxabl?

I am now getting my first home and iwant to airbnb the bottom half of the home and fix it up nice to attract high quality travelers.

Alternatively, with color of title you can rent the property immediately, keep all the rent if none of the other heirs step up to probate the property. 

To answer some of @William Collins’ questions and give more insight here’s the plan:I don’t have a ton to put down now which is why FHA is attractive.

But I feel you'll get steadier numbers near year round attractions.

Alternatively, you could borrow against the property and use some of that equity to buy another property.
