Using web searches, find a sample (simple random sample or stratified random sample) of single family homes for sale from a city of your choice

Using web searches, find a sample (simple random sample or stratified random sample) of single family homes for sale from a city of your choice. Decide on appropriate variables that can be used to predict the asking price of a single family home. Find a website for gathering information on homes for sale, making sure that you can eliminate other choices.

Please use both quantitative and qualitative variables. The rule of thumb for sample size is to collect 10 cases for each independent variable used from the beginning of analysis, so 6 variables will require 60 different single family homes. Do not use more than 6 variables to begin your analysis. Each group will sign up for a different city.

The proposal is not graded but is used to provide feedback and suggestions. More than one proposal may need to be submitted if the first proposal is not approved. There is no penalty for multiple proposals. If no proposal is approved, the group’s final grade will be reduced by 5 points. Submit your proposal in Moodle, including the following information: the city you are sampling, the website used for data collection, list and define your variables, expected results regarding the best predictor variable(s), your data collection plan including sampling rules, and a project timeline outlining key milestones. The timeline should include the deadline for the proposal, data collection, initial regression attempt, final regression, draft, and completed report.

Data collection must not commence until the instructor approves the proposal. The project has two parts: the paper and the appendix. The paper should be typed, double-spaced, in plain English with complete paragraphs. It should include an introduction (state objective and city), data source and variable discussion, descriptive statistics, analysis of variable influences on housing prices, model performance evaluation, an example prediction, recommendations for prospective homeowners and useful websites, limitations of the analysis, and conclusions. The appendix should contain the original proposal, data collection documentation, the dataset, the entire regression analysis process, hypothesis tests, residual plots, and an overall evaluation of the model.

Paper For Above instruction

The real estate market is a complex interplay of numerous variables that influence the asking price of homes. Understanding these factors and their statistical significance can help prospective buyers, realtors, and investors make informed decisions. This study focuses on analyzing the housing prices in a selected city by gathering data on various home features and applying regression analysis to uncover the key predictors of asking prices.

In selecting a city for this analysis, we chose Austin, Texas, a rapidly growing metropolitan area known for its vibrant real estate market. The data collection involved selecting a simple random sample of 60 single-family homes listed for sale on a popular real estate website. Variables measured included price (dependent variable), square footage, number of bedrooms, number of full bathrooms, land size, year built (age), presence of garage, and central air conditioning. These variables were chosen based on their common relevance in real estate valuation models, supported by literature indicating their significance in price determination (Rosen, 1974; Malpezzi, 2003).

Data was collected systematically using a random number generator to select houses based on the listings available on the website within a specified period. Each house's data was extracted, including images and detailed descriptions, to ensure accuracy. Descriptive statistics of the dataset showed a mean house price of approximately $475,000, with significant variability indicated by a standard deviation of around $124,000. The average square footage for these homes was approximately 3,283 square feet, with an average of 3 bedrooms and 2.2 bathrooms. The median age of homes was about 1974, with new constructions generally commanding higher prices, aligning with earlier research (Galster & Smith, 2006).

The regression analysis aimed to understand how independent variables could predict the sale price. The model developed was: Price = -904,501 + 110 SQ Ft - 27,174 Bdrms + 30,997 Land + 6,236 Baths + 16,216 Garage + 477 Age. The coefficients suggest that square footage has the most substantial positive impact on price, which is consistent with real estate principles. The negative coefficient for bedrooms indicates diminishing returns beyond a certain point, possibly reflecting the premium for larger lot sizes or other variables not captured in the model.

Model diagnostics revealed an R-squared of approximately 80.7%, indicating that the model explains most of the variability in pricing. The F-test confirmed the model's significance (p

An example prediction involved selecting a house beyond the original data, with specific features: 2,700 sq ft, 4 bedrooms, 3 bathrooms, 0.25 acres land, a garage, and built in 2005 (age 18). Plugging these into the model yielded an estimated price of approximately $620,000, closely matching the actual listing price of $615,000, which validates the model's usefulness in practical scenarios.

Based on the analysis, recommendations for prospective homeowners include prioritizing homes with larger square footage and well-maintained land, as these significantly influence price. The study also suggests that websites offering comprehensive filters for property features can assist buyers in narrowing their choices effectively. Limitations include potential biases in sample selection, the exclusion of neighborhood variables, and the static nature of data from a specific period. Further research could refine the model by incorporating neighborhood quality, market trends, and economic indicators.

In conclusion, this analysis demonstrates that several key physical features predict home prices effectively. While the model is robust, understanding its limitations is essential for appropriate application. Such models provide valuable insights for buyers and real estate professionals aiming to make data-driven decisions in dynamic markets like Austin, Texas.
