I'm no tax advisor by any stretch, but I believe there's significant financial criteria to meet such as like 50% of the purchase value needs to be added as improvements to the property. 

Mortgages generally aren’t available to U.S. buyers in foreign countries at all and very few US banks lend for purchases abroad.

Prior to Covid I had a lot of luck renegotiating purchase prices based on problems in the inspection.

I'm a newbie, so this question may have been asked and answered multiple times.Has anyone used their VA home loan benefit to purchase a 2nd property, move into this 2nd property as their "primary" residence and rent out the 1st?

I have used this strategy personally more that 10 times and helped many clients doing it.

If these have the 2 position's to make up the puchase price, how can I use BiggerPocket's in finding the 2 lender's to satisfy each position to purchase the cash flowing property?

My most successful Syndication clients over the past 10 years have come from REMentor.

I know that generally 20% down is required when purchasing an investment property.  

On top of the 'commonly used' investor filters like 2+ years back taxes, recently inherited, etc- I loved some additional possible/ unique filters like number of structures on a parcel, min/max land sq ft, initial purchase price, and ability to narrow down to very specific areas on a map.

This is my 3rd tour in Germany and I am also seeking to purchase rental property here as well.Finally, I am planning to do my first house hack upon my return to Baltimore next year.
