Why fewer and fewer people are buying duplexes when they're 150,000 cheaper?

Why don't people want to buy a small duplex? Friends do not understand, less than 1 year after moving in regret a year ago friends bought a new house, when he insisted on buying a small duplex, I advised him not to buy, or he will certainly regret. But my friend said, the family is large, buy duplex house is better, finally he still bought a two-story house. Not long ago to go to his home, a door into the feeling is not very good, the friend is also sighing, said regret, which only moved in less than a year.

So why wouldn't someone want to buy a small duplex?

First: ventilation and poor lighting

The use of the duplex floor area is much larger than a suite of small homes, but it is deeper than the smaller, if the duplex is a combination of inner corridor plan, which will directly lead to the direction of some duplex models are not good, which affects the interior of the lighting and ventilation.

Second: the high cost of late maintenance

State regulations higher than 2.2 meters of floor height needs to be counted in the floor area, but the small duplex played a ball, the height of the second floor is just a little short of the height of the real estate certificate is written above the area of a single floor area, the sales staff told you to buy a two-room house, the area of 80 square feet. 80 square feet, but the contract as well as the real estate certificate written above are 40 square feet, so the later payment of property costs and heating costs are levied in accordance with the area written above the real estate certificate.

Third: poor visual sense

Because the duplex is a double, so when we bought two rooms eighty square feet, downstairs 40 square feet, in addition to the amortization of the next is about 30 square feet, the visual sense of the poorer, to see the area of the smaller. So buy duplex must buy big, at least in 120 square feet or more, too small to look at will suffocate.
