Abstract:
This study used financial tools to check the variables. In so doing, the return of a pre-built housing project and that of a pre-sale housing project could be compared. The study focused on Warangkul the Private Housing Project, Klong 3. It was found that a number of units sold a month, the sale price, the price of land, the construction cost, the interest rates, the construction period and the ownership transfer were variables affecting the return of investment. Debt to equity for pre-built hosing project (1.60) was less than debt to equity for pre-sale housing project (2.65). As for the pre-sale housing project, the return on investment was 22.85% and the return on equity was 85.75%. These rates were higher than those of the pre-built housing project. Its return on investment was at 19.55% while its return on equity was at 50.89%. If there was a change in variables, (a 10% increase/ a 10% decrease,) the most influential variable was the sale price. If that was the case, the return on investment of the pre-built housing project would increase/decrease by 7.32% and its return on equity would increase/decrease by 18.79%. However, the return on investment of the pre-sale housing project would increase/decrease by 9.05% and its return on equity would increase/decrease by 38.05%. The least influential variable was the number of units sold a month. If that was the case, the return on investment of the pre-built housing project would increase/decrease by 0.06% and its return on equity would increase/decrease by 0.16%. However, the return on investment of the pre-sale housing project would increase/decrease by 0.03% and the return on equity would increase/ decrease by 0.24%. Based on the values of probability when there was a change in a variable, in terms of pre-sale housing project, the price of land was the most fluctuating variable (14.55), followed by the ownership transfer-the construction period (14.51), a number of units sold a month (13.65), the sale price (11.57), the construction cost (11.26) and the interest rate (6.86). As for the pre-built housing project, a number of units sold a month was the most fluctuating variable (15.69), followed by the price of land (14.55), the sale price (11.57), the construction cost (11.26), the interest rate (6.86) the construction period and the ownership transfer (4.03). It can be concluded that initial outlay, a number of units sold a month, the construction period and the ownership transfer were important variables affecting the return of pre-built housing project and pre-sale housing project.
