Task prompt

I am evaluating whether buying a home is financially sensible compared with continuing to rent. I want a reusable, evidence-based decision model rather than a simplistic “buy versus rent” calculator. Research the major financial components that can materially change the result, including mortgage structures, fixed- and variable-rate borrowing, property taxes, homeowners insurance, maintenance and repair costs, HOA costs, closing and transaction costs, refinancing, opportunity cost of the buyer’s upfront cash, investment returns on capital that remains invested when renting, and long-term affordability. Use authoritative government and regulatory sources for tax, mortgage, consumer-protection, and lending rules where applicable, supplemented by reputable financial institutions, housing organizations, academic or independent research, and credible financial publications for market and methodology context. Prefer primary sources for rules, definitions, lending mechanics, and consumer protections. Do not rely on promotional mortgage calculators or marketing claims as the sole evidence for important assumptions. Start by defining a consistent rent-versus-buy framework and identify the costs and assumptions that a conventional calculator can omit. Research several realistic financing structures and determine how their different interest-rate mechanics, upfront costs, repayment patterns, refinancing possibilities, and long-term risks affect the comparison. Build the analysis so that findings from the research phase determine which assumptions and financing scenarios need to be modeled rather than simply filling a predetermined template. Model the comparison under multiple interest-rate, home-price-growth, investment-return, holding-period, maintenance-cost, insurance/tax, and transaction-cost assumptions. Clearly distinguish documented facts, estimates, assumptions, and calculated outputs. Show when buying becomes more or less financially attractive and identify situations in which a seemingly favorable mortgage or purchase price does not produce a favorable long-term outcome. Investigate costs commonly omitted from simplistic rent-versus-buy comparisons, including transaction costs on both entry and exit, financing fees, insurance changes, property-tax changes, maintenance and major repairs, HOA assessments, refinancing costs, opportunity cost of the down payment and other cash tied up in the property, selling costs, and the difference between building home equity and receiving an investment return elsewhere. Do not assume that any one of these costs is always decisive; determine their significance through the evidence and scenario analysis. The final deliverable should be a reusable decision model that another person can apply to a different property or financing scenario later without rebuilding the methodology. Preserve the assumptions, source evidence, calculations, sensitivity analysis, major uncertainties, and conditions that could change the conclusion. The model should support a reasoned decision rather than automatically favoring buying or renting.
