It is usually difficult to take money against it from the bank, it might not be a 1:1 value add - meaning if you invest 100k into an adu it might not raise your value by 100kThat being said, it can be pretty lucrative especially in expensive and sunny CA - since building lots are no where to be found and existing real estate returns are very poor.My partner builds these units.

It also gave me the chance to experiment with short-term rentals before transitioning to a long-term hold, reinforcing my strategy for growing a real estate portfolio.

I'm working with a real estate attorney to help me with transferring the deed.

Btw, I learned about this from a book about the career of Harold Helmsley (pre Leona!)

We were the ideal customer of a real estate investor. 

In terms of finding a partner, I would recommend partnering with someone who has something that you don't have (understands renovations, real estate experience, has money, etc.)

There are all kinds of plans and ways to “make it” in real estate.

Quote from @Victor Patel: I have went to many real estate and franchise conferences over the last 30 years. 

We have a 14-page management contract that we've added our real experiences to over the years, with the intent of protecting both us AND the landlord.

If you want to acquire more real estate I suggest more savings or sell the other property with equity.
