Then based on @Michael Baum's suggestion, I think I will have my cleaner and/or maintenance person do monthly/quarterly maintenance like using using enzyme based cleaners, grease fighting drain treatments and hot water flushing. 

Any realtors out there can suggest any and explain your experience with them?

Prior to diving in I would suggest a few things: I agree with @Kevin SobiloInvest in relationships and knowledge before taking the leap1.

The interest rate is 7%, so we suggest this property is for someone who wants to get into Lease Options and meets the other requirements such as adequate reserves and credit.That means, they buy the property, they wind up with $50,000 in equity and they do a Lease Option to a buyer who doesn't currently own a house, but wants to.

Inconsistent Cash FlowUnlike traditional jobs, real estate doesn’t provide steady paychecks.

The consistent population and job growth are driving real estate values along with many companies choosing to move and develop here like Intel, Amazon, Google, Meta, etc.

They are investing in infrastructure, housing, public safety and taking the steps they need to take to attract more jobs. 

On the other hand, I’m hesitant to simply pay down more of a property, as we don’t need the immediate cash flow.Fortunately, both my wife’s job and mine are recession-proof, which allows us to be a bit more aggressive with our investments.I’d really appreciate advice from investors who have experience with frequent moves or military service.

experience: I’m on my 3rd flipage: early 40sday job: brand and web design/development retirement savings: noneI want to learn about buy and hold to secure having SOMETHING for retirement!

If I don't do any of these courses, any other resources someone suggests for help in getting started on arbitrage?
