I think the first decision you need to think about is whether you want to be passive or active. From your post and subsequent comments, it seems that you want to be a passive investor. This makes sense as I imagine even with a reduced schedule as a doctor, you probably have limited time to devote to real estate investing.
I started as an active investor and I was not very good at it, I was fortunate to be rescued by the market which is not something that is possible these days. I think to be effective as an active investor you need to have some kind of advantage over others in the market - rehab skills, market knowledge, time - something to give you an edge. If you don't have any of that, you will likely generate better return investing passively - but it's critical to understand what it means to be passive. As part of my journey, I bought turnkey single family homes thinking it was passive. It was not - I had to find and evaluate the properties, find lenders, close the deals and then manage a property manage. It was definitely not passive.
I started my true passive investing journey when I found real estate syndications. It is still not completely passive - you need to vet the operator, analyze the deal and market - all before you invest. But after you send the wire - you are completely passive. You will collect reports and distributions (hopefully), but there is nothing else for you to do. I found that the returns matched or exceeded my active real estate investments.
There are downsides to syndication investing - these are long term investments that are completely out of your control and provide no liquidity. That said, it's ideal for busy professionals and if you do it right, you won't pay taxes on your gains.
I would recommend you join a Community of passive investors - this was a game changer for me as I was able to learn from others, collaborate and find quality operators.
Good luck!
