Methodology & Assumptions
Median home price uses Zillow Home Value Index (ZHVI)[1]. Median rent uses ZORI; where ZORI is unavailable we fall back to HUD Fair Market Rent[2].
Median household income is the Census ACS 5-year estimate[3].
Property tax rate is the effective rate from the Tax Foundation[4]. Actual millage varies by county.
Mortgage calculations use 6.4% (Freddie Mac PMMS · week of ) national average 30-year fixed rate (PMMS)[5], 30-year term, $1,720/yr Colorado average homeowners insurance from NAIC[7], and 0.5% PMI when down payment is below 20%.
"Income needed" uses the 30% front-end DTI rule: monthly PITI ≤ 30% of gross monthly income. The price-to-income ratio (P/I) is computed as median home price / median household income; 3x or below is generally considered affordable, 4–6x challenging, 6x+ severely unaffordable.
Rent vs. buy assumes 3% annual rent inflation, 3.5% annual home price appreciation, 3% closing costs, and compares 5-year cumulative cost. "Breakeven year" is where cumulative ownership cost minus equity falls below cumulative rent.
Federal tax in the take-home calculation uses IRS single filer, standard deduction; state tax applies the top-marginal rate after state standard deduction; FICA = 6.2% SS + 1.45% Medicare.
Context for median sales price cross-references the NAR[6] where applicable.
