Say the house has a value of $250k, and assume you sell it at the same value 3 years later. At interest rate of 7% the interest portion of the mortgage alone is 17,500 per year or $1,458 per month. Your can throw in more down payment to reduce interest, but you lose the investment return on the down payment, so it's the same deal. For $1,458 per month, plus the property tax and utility for the house, we are looking at $1,800/month or more, for which you can rent a very decent 2-3 bedroom condo, all utilities included. I haven't talk about the lawyers fee, sales tax, furnishing the house, cost of you time...
First anyone abroad will gradually lose the feel of the market there, second it's a giant bubble for sure. What will happen when you play with a bubble when you got no feel?
