With 25 votes in, I'm glad to see number 4 is at zero, surprised to see ten for number 1.
I have not voted but I'm at number three, some reasons why.
1. US financing is at historically cheap levels. Overseas financing is less favorable, shorter terms, higher rates, etc. With a equally stable well qualified partner or two, US home equity could be used to pay cash for the foriegn property and establish an escrow type account.
2. With a 10-15 year retirement window max usage in that period would be 4 weeks yr. Leaving 40 or more weeks a year open for rental. At 10-15 years, usage could be adjusted to 4 or 6 months per partner.
3. While rental income can offset some costs there are no guarantees. With a partner or two or those costs are cut in half or even a third. This reduces the opportunity costs of such a large solo investment.
4. The odds of finding some one with matching interest and means for this type of thing within family and friends circle can be rather small.
