What is the conforming loan limit in Arapahoe County?

Why does Denver have a higher conforming loan limit than most of the country?
Denver-area counties (Denver, Jefferson, Arapahoe, Adams, and others) are designated high-cost areas by FHFA because local median home prices exceed the baseline threshold. The 2026 conforming limit for Denver-area counties is $862,500 — significantly above the $832,750 national baseline. This allows more buyers to access agency financing rather than jumbo loans.
How does Colorado wildfire risk affect homeowners insurance?
Wildfire risk is a growing concern for Colorado homeowners, particularly in the Front Range foothills and mountain communities. Some insurers have reduced coverage availability or raised premiums significantly in high-risk ZIP codes. Buyers in wildfire-prone areas should research insurance availability before closing — not being able to obtain homeowners insurance can derail a purchase.
What does PITI mean and why does it matter in Arapahoe County?
PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a full monthly mortgage payment. Lenders qualify you based on your total PITI payment, not just principal and interest. In Arapahoe County, property taxes and insurance can add hundreds of dollars per month to your P&I payment, so it's essential to use a calculator that includes all four components.
What credit score do I need to buy a home in Arapahoe County?
Most conventional lenders require a minimum 620 credit score, though the best rates go to borrowers with 740+. FHA loans allow scores as low as 580 with 3.5% down, or 500–579 with 10% down. VA loans have no official minimum but most lenders want 580–620. Your credit score affects both loan eligibility and the interest rate you receive — a difference of 50–100 points can change your rate by 0.25–0.75%.
