You mentioned that you are interested in passive income. I think the most important first step is to define what that is! Passive income, to me, is where you do the upfront work (vetting partners, researching the market, analyzing the deal) and then you invest your capital - then it becomes passive and you (hopefully) collect distributions.
Managing a contract who will do the work, managing an interior designer, managing a property manager - those are all active actions you take after you buy the property. Owning the real estate 100% yourself means that you are an active investor - you will not be passive.
I started out thinking I was a passive investor. I bought single family properties, hired a property manager and thought that I could just sit back and watch the cash roll in. That was not the case. I had to manage the asset - that means actively engaging with the property manager, the handyman and contractors and often the tenant. I was constantly having problems with well-vetted property mangers. I was not good at managing the asset. Part of the reason is that I was an active investor and thought I was a passive investor.
None of my properties cash-flowed like I had projected, but lucky for me - I did this in a market that even bad asset managers saw their properties appreciate. So I made money.
Eventually, I realized that I wanted to be a passive investor and what I was doing was active - that's when I found syndications. This is where you do all of work up front - vet the operator, analyze the deal, research the market - and then you wire some amount (typically $50,000 or $100,000) to the operator who manages the asset. You own a small portion of the asset and receive distributions based on the performance.
The advantage of this type of investing is you are effectively hiring an professional asset manager - this is their profession. They do all of the active management of the asset and send you distributions and reports. There are downsides - you have almost no control of the asset, it's very illiquid and they are long term deals. But - for me - the advantages clearly outweigh the disadvantages. My returns are higher, my stress is lower - and I am using my strengths rather than my weaknesses.
I think the first thing to do is determine what "passive investing" means to you. To me - owning real estate that I manage is not passive!
