Having a long-term rental while living abroad is do-able.Flipping houses while abroad, in my opinion, more difficult, especially if its your first go around with real estate.I would recommend taking a flight and staying in the area for a week and inspect the neighborhoods and make connections.You can reach out to @Elenis Camargo who has a PM company in Jacksonville.Best of luck though.

The tenants have paid and if someone is thinking about moving out then an extra surcharge that hits if they aren't out in time for us to turn the place for a lucrative AirBNB short term rental can help massage the move out timing.That said with MTR we do not have the cleaning costs that eat up a lot of STR gross, and its lower hassle in some ways.  

I have 8 long-term units, 3 mid-term units.

There is a flaw in the business model and thier internal processes need a lot of work.First the good,Yes, I got paid every month.Nomad found me good renters.Next the badDue to needing to make the guaranteed rent they rented my unit below market valueIn communicating with Nomad they were disorganized, often sending conflicting messages and not alignedNomad offered to find me a repair company, that compnany charged $400 for a $25 dollar part and I was stuck with Nomad saying "not their problem" and the vendor saying Nomad was the client not me.Nomad was horrible to my renters as their property management term ended.

Used houses in the area sell anywhere from $75-125 a square foot.These are long term rentals that I do not plan to sell.I am reading the Rental Property Investing book and implementing the method that focuses on cash flow and that strategy states you need to have $300 cash flow per month, per property.

I have done my underwriting for 2 years with zero near term appreciation. 

However, this increases your exposure to risk, especially in terms of vacancy, repairs, or market shifts.

Rent my house in Philadelphia out, and move to puerto rico as a renter with the goal to buy for myself more so than to rent for short term.

The city where you invest determines all long-term income characteristics.

That will put us into the long term capital gains category on the sale.
