1. LOAN PAYMENT PRINCIPLE AND INTEREST: To get the monthly principle and interest payment go to this website for a calculation: http://www.amortization-calc.com/.
2. HAZARD INSURANCE: To estimate the insurance annual payment, multiply the purchase price by .0033. Divide by 12 to get the monthly payment.
3. PROPERTY TAXES: To get the estimated annual property tax on a property visit the county assessor's website. In Bernalillo County that web address is: http://www.bernco.gov/property-tax-calculator/. Divide the annual property tax by 12 to get the monthly payment.
Add the monthly payment, plus 1/12th of the hazard insurance and 1/12th of the property taxed together and that is your estimated monthly payment.
