I don't disagree that Airbnb claims can be difficult but this is all very common in the industry. 

The building itself cannot be accelerated. 

Hello @Hudson Filippi FHA does have a One Time Close construction loan that will allow you to build a home.

I don’t believe you can do a 1031 into building an ADU on land you already own, even if it wasn’t your primary.Reach out to @Dave Foster if anyone knows he would.

Go to BUILD YOUR TEAM at the top of the screen and look for local investors or meetups in your area.

One is focused on real estate and its all military folks and vets (I'm active duty Navy) and the other one is focused on being well rounded, while also building wealth and passive income.

It can be done for new build but not rehab since all rehabs are different. 

I have on multiple occasions, once with one of my own properties and a few times for clients been able to not only get the money they paid for a property but also gave them extra money in a total loss (protected the equity that has accrued due to inflation in the industry).  

What worked for me was focusing on building strategic relationships with top tier people (quality partners) who could complement what I brought to the table—sales, management, and execution.When you are approaching sellers for creative financing, leading with a clear value proposition (and CONFIDENTLY) is key.

@Carlos C.Mark Kohler is well respected in the industry.
