The other 50% just don’t understand real estate law, real estate principles, real estate finance, and real estate agency.  

There's a high chance that you are feeling FOMO from the returns in public markets, sell your houses for a loss, pile into stocks, and then see mediocre performance while real estate heads back higher again.I see this, and similar actions, play out over and over.Personally, I'd stick with the real estate rather than selling it.

Sorry for the following Contrarian advice, but you're not a 5 year old so:The only reason to buy a personal residence (Home) is because someone is forcing you to.Usually, this person is called your Spouse (which is Latin for someone who forces you to make horrible financial decisions then criticizes you for them endlessly:)perhaps DON'T buy a home, just rent something affordable and invest the 20% or in your case 50% into the stock market (sp500 16.1% yearly return last 15 years, 11% last 50 years, 10% last 125 years)remember, your RENT is your maximum monthly housing expense, but your Mortgage is your minimum or starting monthly housing cost, it always goes up from thereI've, owned 2 personal homes, 100% appreciation in 6years on #1 and in 7 years on #2, (I timed our market perfectly both times), with 20% down and very low mortgage rates, but after honestly calculating all expenses, only made about 5-6% a year "investment wise".

They own all their properties and their stocks and bonds in their own country and they get all their W2, business and social security income from their own country as well.

Quote from @Scoop Schneider: 86k principle 7.5IR 360 months 800 credit score 1st position Put it on paperstac. my guess without dropping it into any calculator would be its worth $50-$70k assuming property value is above $100k

For others, it may be diversify into stocks.

As expected, he recommends Roth conversion and invest in stocks. 

I would expect start-up costs such as stocking linens/bedding, upgrading certain furnishing and amenities, and pass-through costs for listing on the OTAs (like VRBO, Airbnb). 

For instance, a worksheet calculator that you can depend on for accurate rehab numbers, a coach or mentor that has experience wholesaling whose brain you can pick, a curious, principled solution-based mindset, willingness to find sellers that are NOT on the market, and for good measure -- steal underpants!

The principles would still be valid though
