My personal favorite that I've used is Designer in a Binder.

I assume if one wanted to 1031 for "rinse and repeat" you'd also be game for that as well. 

Considering traveling nurses/workers, as well as seasonal rental for ND home games (also a huge Fighting Irish family).

All depends on what your goals are and what market fits your game-plan/criteria 

My future game plan is looking to buy a condo with 50% down payment and pay it off within 3 years.

So, I'd like to get ahead of the game and start working up a plan and a strong argument for it which I can use when the time comes. 

My experience has been that purchase transactions where the buyer has no or little skin on the game have a default rate many times that of buyers who place a significant down payment into the deal.  

Real estate investing can absolutely be a game-changer when it comes to freeing up your time and helping shape the community you care about—especially in our beautiful region.You’re on the right track by diving into BiggerPockets.

Portland ME is a favorite of mine.  

That's their whole game!
