@Andrew Steffens arbitrage based on a long term triple net lease has no drawbacks.

Obviously I'm asking cuz I don't know the drawbacks and benefits in comparison RentRedi challenges already covered by @Stuart Udis

One of the big drawbacks, is that the seller will want to be released from the loan eventually, so they can buy another house.

The main drawbacks are the fees/rate & the prepayment penalty. 

@Mike Eichler,There is another option With the benefits of new construction without the drawbacks of the timing.  

The drawback is that these are properties would be owned by the 401k or SDIRA, not by you, and thus you would need to be very hands off, for instance you couldn't self-manage the property, but instead will need a third-party property manager.

Being close to Orlando, major healthcare facilities, and big employers definitely helps.

They both should be better able to provide you the benefits and drawbacks of each one, as the reason for either one depends greatly on the specific facts of your situation.As a third possible alternative, you may want to ask about a Series LLC.

In reality, however, one year could include a $10k roof replacement while the following year could have near-zero major repairs.

I have been networking with some agents around the area but the majority are salespeople/ specialists in marketplaces other than "buy and invest" for the long term.
