Was just able to get another client pre-approved in California to purchase a home with 100% of the down payment coming from Bitcoin. He should be commenting here on how the process has gone so far.
It is definitely getting easier as time goes on

Things may vary state to state depending on which investors are lending in certain areas, so please don't hesitate to ask any questions.
Hi everyone -
I am the client referenced above and I can confirm that everything keithers has said is true. I tried reaching out to multiple lenders which all said it was not possible before finding keithers on this forum, so I was initially pretty skeptical going into it. However, he quickly showed me that he was serious about his claims; and in fact, the whole process has been much easier than the first time I went through the process years ago with a big bank.
Additionally, he is incredibly responsive and easy to work with. He has also proven to be very knowledgeable both in terms of bitcoin/crypto and mortgages/real estate. I would highly recommend giving him a shot.

Feel free to PM me if anyone has any questions. Sorry for the delayed response back in December, I wasn't active on the forum, but I am back here and will be around to answer any questions or provide any help that I can to fellow Bitcoin users...
