Dave,
I would have to respectfully take issue with many of your points based on fact, not opinion. That does not mean you are not entitled to your opinion, but I a a financial guy and although I do not live in BA full time, I have bought and sold real estate there and own an apartment etc. I will take them point by point
1. It is true that there are few if any mortgages and that it is a cash deal, this is particularly good because the market is not based on speculation, bad valuations and false pumped up values, it is a real supply and demand market which allows for orderly markets and stability in the system. You will not see values drop like in the USA where we all know what happened. The issue back in 2000 and 2001 was the peso was artificially pegged to the dollar and was not free floating, this cause a severe devaluation which also happened in Mexico. The peso is not "pegged anymore" and is free floating. Yes it can lose value against the dollar and has recently but that is based on market cycles, not the government devaluing the currency. The dollar has gained strength recently and will for the next 12 months but once the deficits and the national debt of the US get to a point where foreign countries quit supporting the borrowing, the dollar will fall and inflation will kick in the USA. That being said, the lessons learned from 2001 were to price things in dollars so the market has stability. Second, most people that do CASH deals is because they either do not trust banks or want to do this in "NEGRO" or under the table. That is not the way to do business and I have wire transferred money from the states and had it wired back and the banking system does allow for this, you just have to go to their "relaciones y comercios exteriories department and present the boleto or escritura and there is no retention if funds. Many foreigners have had problems because of really bad advice and doing things NEGRO instead of BLanco. SO you can avoid the cash deals and they can be done at banks although the money is exchanged there.
2. You are completely backwards regarding the capital gains taxes and I am happy to send you the legal references. I use BDO Becher in Argentina as my accounting firm and they are part of BDO Siedman, 5th largest firm in the world. There are NO capital gains taxes in Argentina. Foreigners do not pay any taxes on the gains from sales as long as they are done in Blanco. The only taxes that are paid on real estate transactions are the traslado de domino, sello etc which amount to 2.5% of the price for seller and buyer. This included escribano fees. That is a title transfer tax etc which you have everywhere in the world at some rate. If you are a resident, you are not taxed as long as you roll it to another property. Where people have been burned is they did it in Negro and then when it came time to sell, it was never registered properly and there is a retention of 30% of the amount for at least a year. This happens because things have been done improperly, not because that is how it is. With repsect to fees and commissions, it again depends on who you deal with, in Negro you get totally screwed everywhere. If done properly the buyer pays the commision in Argentina and usually it is 4%, so you pay 4% on the buy and they pay on the sale. In the US, seller pays 6% so it is cheaper in Argentina. You can avoid commissions if you buy direct from the owner. What fees? THe escritura is 2.5%. That is not onerous.
3. I dealt with number 3 above regarding the currency issue, again we forget the USA is in major trouble, people are losing their homes and equity has been wiped out. Whym the mortgage system. Argentines lost confidence in the banking system in 2001 and now Hard Assets and real estate are their assets of choice, that will not change and although values may not go up as they have over the past few years, blue chio areas such as recoleta, Palermo, Belgrano etc will not lose value.
I just think point 3 is defeatist and not much I can say other than I just totaly disagree and that is what makes markets.
Also, let's assume you could have bought an apartment 7 years ago and let's inflate it to 80k (cheaper back them for a 60 meter apartment) but 80k. You paid rent averaging 500 dollars a month for the last 7 years, that is 6k a year x 7 42k in rent. Let's say you bought and wanted to leave at year 7. You would have to have lost over 50% of the value to lose money. That just has not happend. The currency exchange is what did that in 2001 but not gonna happen, has not even happend in most of USA with this disaster. If it stayed the same, you made 42% on your money over the 7 years and any appreciation is gravy. So, I think the economic argument is one that different people can differ on but I think my argument is solid. I would agree if you planned only to stay 1 or 2 years renting makes sense but longer than 5, buying is a better deal.
Now, why do many people rent and not buy, they do not have the cash to buy a place outright and since mortgages do not exists per se they cannot buy.
I respect your opinion and your right to that opinion but I disagree completley with most of your points. It is a shame that many expats get bad advice or get taken advantage of because people say, that is how it is here, but I assure you, there is a way to do things right, and for most people, the promise of saving money by doing it under the table in Negro to save some money turns out to be one expensive and painful mistake to fix.
Thanks
