If you’re looking to build long term wealth, accumulate assets, take advantage of tax code, and benefit from appreciation, then play the appreciation long game.

I don't know, that's a personal preference.

Personally I’d stick with SFR or at 4 units or less for preferred financing and to reduce risk of the exchange failing.

I would be amazed, shocked even, if a traditional financial institution was willing to lend on a non-habitable asset up to 80%. 

He has tons of videos on each country and the viability of the asset for people buying internationally.

The alternative is to set up a self-directed IRA, or better, a truly self-directed Solo 401k plan, invest in alternative assets, and then do the conversion.

Preferred returns would even be acceptable but not a straight interest rate play if the lender understands the structure. 

There are asset protection companies who make lots of money off this - I talked to one who said it's $13,000 (for 4 properties) to set up layers of protection then annual fees after this. 

I have about $400K to deploy, but would prefer to buy several duplexes rather than 1 more expensive building.
