Once leased, I call them and have power cancelled.

Leases expire mid 2025. 

Most condos in the DC area require minimum leases of 6 or 12 months.

I am considering getting into some commercial investments and think I want to go down the NNN route. Are there any books or resources you can recommend to get me started with the basics?

Quote from @Arvand Sabetian: Does your lease state you're providing internet for the tenants?

Doesn't sound like a lease option at all.So, after 5 years you get the $2k-$5k down, the little bit of amortization payments, and the difference of $875/mo and $667.33/mo? 

But we also added lease options to our model which attracted a better tenant and lessened the the amount of work that it took to manage the lease option properties.So I would encourage you consider investing in your own back yard before going out of state, especially if you live in North Carolina. 

We removed a chimney to open up the space and updated all the major ticket items—new electrical, HVAC, and roof.

I myself have a 1/1 apartment on Davis Islands near the hospital that I'm considering renting to traveling nurses.The problem with rental arbitrage is that you need leverage as the renter to negotiate assignable lease terms with your landlord.

It's no different than those who hold stocks, then need to liquidate to purchase items.
