Monthly rate \\( r = 0.005 \\)  \n2. Compute \\( (1 + r)^n = (1.005)^{180} \\approx 2.4596 \\)  \n3. Numerator: \\( r \\times (1 + r)^n \\approx 0.005 \\times 2.4596 = 0.012298 \\)  \n4. Denominator: \\( (1 + r)^n - 1 = 2.4596 - 1 = 1.4596 \\)  \n5. Fraction = \\( 0.012298 / 1.4596 \\approx 0.008425 \\)  \n6. Monthly mortgage payment = \\( 160,000 \\times 0.008425 \\approx \\$1,348.00 \\)\n\n---\n\n### Total Monthly Payment (with HOA)\n\nAdd HOA fees of \\$150/month:\n\n- Mortgage payment \u2248 **\\$1,348.00**  \n- HOA fees = **\\$150.00**\n\n**Total monthly payment \u2248 \\$1,498.00**\n\n---\n\nIf you want property tax, insurance, or other costs included, I can estimate those too."
