Hey @David Wilson - you raise a good point. I suspect because you're in the Commercial Real Estate Forum that you've tried res real estate and found that in many cases, the size of deal is generally small- making it difficult to generate enough cash flow (or capital appreciation, unless you're doing a significant rehab/development - which is a 2nd job).
Here's the best advice I would give you, based on the limited knowledge I have on your situation. I will base it off other physicians I've helped invest in commercial properties.
1st- investing activity in commercial real estate does require time and energy. Now, the nice thing is, if you focus on Core assets or even light value add in good locations, you should be able to minimize the amount of time required.
The bulk of the work is done upfront in a commercial deal
- - finding the property
- - negotiating LOI/PSA
- - Due diligence
- - Financing (equity and debt)
- - leasing
- - finding the team (management/leasing team)
I'd say, allow for 2-3 months (once you find a deal). This is not all consuming during Due Diligence- but there will be time required to manage the process and consultants.
Ok, once you have the property and team in place to oversee- in most cases a professional property manager will minimize the time required on your part. I'd say- 1-2 hours a month to 'Asset Manage' your property. You make long term capital decisions and big picture. Your property manager deals with day to day.
Generally, I like light bay industrial and retail - as the leases are longer and thus less day to day. Office can be ok, but your Cap X is more significant when a tenant leaves.
I've written a few articles and videos on this exact scenario. Busy professionals who have money but not interested in creating a 2nd job.
The biggest challenge- I suspect, for new investors to commercial real estate is that learning curve to Commercial is steep. There is little cross over from Res to Commercial.
So finding a good team to help you identify the right properties and proper financing is crucial.
I think the bigger question is this: "Is it worth the energy and time to learn how to invest in commercial real estate?"
I'm bias- and believe the answer is yes. Even if it takes you a year or 2 to get a great commercial deal - one good property in the right location can (or go along way) to replacing your income.
You control the asset. You have cash flow today. Attractive tax deductions.
Alternative: Find someone you trust to invest with. It would still be prudent to fully understand the deal so you understand the risks and the partner. But, that is a viable option and you can learn from the inside so to speak. Don't expect the GP to teach you- but, you will learn some valuable lessons during the investment.
Hope that helps.
