I personally think commercial is best with triple net leases-it minimizes the work and calls.

I have personally run across a scenario where a guy took a 60-day rollover, used the money to buy private stock that was "certain" to double or triple in value in a short time, thinking he could pocket the return on investment and put the original amount back into another IRA within 60 days.  

I could be off of course, but id just triple check your rent estimates.

In the last 12 months, I purchased 2 properties (a duplex and triples) in Hamden CT; and will be closing on another triplex next week.

They are organized, produce a marketing plan, and reinvest their money to double or even triple their marketing efforts.

I would double/triple check those before I ever looked much further into SFH->MFH.

Some on the other hand really enjoy thattype of work.Maybe if you are worried about management get into buying notes at a discount or buying triple net properties where the check comes every month.

My wife and I got out within six months of each other and even though my income as a civvie tripled over what my wife and both made when we were in, we lived lean for three or four years and just saved.As to advice about investing, read, read and read some more.

With sellers wanting to sell their land that sits near the development of these corporations, do you think the land value of commercial zoned will rise double or triple in value?

As to charging a higher rate absolutely just be aware of usury laws in your state regarding interest rates..That is one of the many reasons I use a land trust to avoid the DOS and lease out on a triple net lease NNN basis to a tenant.You can also sell the note as long as it is structured correctly so keep that in mind when you setup the note/contract..I am going to a advanced note training this weekend so hopefully will learn how to best do that.Mr Finance examiner is correct in his analysis in that more information is needed to give better answers to your inquiries.Good luck.
