There's also the possibility, and I know many people think it's unimaginable right now, is that the developed world total debt will become so huge that the powers that be decide to wipe everyone's slate clear, and declare a single, new currency.

Currency may become irrelevant.

They will also require an unexpired passport and bank documents converted to English if not already in the language and foreign currency converted to U.S. dollars.

I'm 68 and "retired", so do not want to commit to a BUSINESS and am not sure RE can be done as a "hobby" with great success.At present I trade currencies and options, but that is capital intensive and inconsistent income-wise.

Also seems smart to have an income source from another country as a hedge to currency fluctuations.Anyone out there feel different?

Now concerning market risk of a deployment, natural disaster, collapse of the currency or running out of oil or anything.  

If cryptocurrency is just another currency, then accepting it is no different than, say, accepting Euros, Canadian Dollars or British Pounds for your vacation rental then converting to USD.

I know it can be done because I've sat on google translate to annotate German tax returns into English, along with past-dated USD currency conversions to get a loan through, but yeah this is one where you need to shop primarily the competence of the lender, and shop it hard.

Hi DonaldInvesting overseas is a better way to expand your business.Things to consider:1) You must do extensive research on the country you would like to invest. 2)Know the legal, tax, insurance, currency exchange, tranfer taxes issues3)Don't assume that markets with low debt ratio are good for investment4)Work with Certified International Property Specialist(CIPS), TRC's(Transnational Referral Certified Agents), ICREA or FIABCI members to help you find International properties and provide you knowledge of the particular country and market.Dubai was great for flips, but not anymore.

Currency risk, the chance of being sued, finding a good team (especially a good property manager), not knowing the market in terms of good areas/streets to purchase within, having to rely on others people’s opinions to a certain degree (e.g real estate agents), and the general risk of distance – if something goes seriously wrong, not being able to be there in times of need.
