I can't speak for your state but in Ohio as I understand it unless the employer is negligent (like knowingly removing a safety guard off a piece of equipment) the employee is not supposed to be able to sue for compensation beyond what Work Comp pays.

Can't speak for others, but I personally would appreciate if a colleague of mine ever catches an error in the work of my firm and brings it to my attention.

We are currently working on three four plex unit deals as we speak. 

Something I've started paying closer attention to is whether a Seller who is getting a property tax rebate is actually entitled to it. 

@Dane KaniaHiya Dane-As a fellow Realtor, I’d highly suggest speaking with your managing broker.

For the finer details, I'd suggest reading a book or two and/or speaking with a good real estate agent, lawyer and CPA that understand investing and can help you with many items on your list.

I can speak from experience, not as a medical professional, but as someone who has worked in commercial real estate and is very close friends with multiple medical professionals (surgeons, doctors, etc.).Focus on yourself and your practice firstIt sounds like you are enticed by the "idea" of passive income, but have no land-lording experience to understand that this isn't truly a passive business.Doctors (painting with a broad brush here) aren't known to be good business people or good with their financesMy theory on this is because they are in school until their 30's living on student loans.

Year-end comes and the CPA will be spending countless hours to fix the financials and bill a huge amount for the work without a reliable person to speak to on what went on during the year of operations.

Either way, you need to speak with a lender and plot & scheme this out.  

That's your real return.Best way to find out cap rates in your market is to speak with experienced brokers who deal in the asset class you're interested in.
