It sounds like your parents went the traditional route of investing.

It is very efficient, much less cost that traditional electric heat and is heats with far infared waves which heats objects not air. 

This would be considered a rooming house and has different/specific regulations in many areas as opposed to a traditional rental.  

There may be innovation that drives the Ag market but the traditional markets are tight. 

Airbnb's tend to have higher expenses than traditional rentals due to the higher management fees and covering all of the utilities.

A traditional refi has the least risk, the HELOC has the most.  

Traditionally, even in investing heavy careers like portfolio management and investment banking, the generalist model was the way go.

Hey @Kris Lawhead, a tip I picked up on BP podcasts was that if you only hold the note vs you and wife (if married), then you can get more loans....traditionally only allowed 4/person....if get them separately you can get 8 collectively. 

Would it ever make sense to seek traditional bank financing (assuming the property is financable), use a portion of your HELOC for a down payment and rehab expense.

@Stephen Akindona.That might the best "turnkey vs. traditional" investing reply I have ever seen.
