How much do I need to earn to buy a $400,000 home in New Mexico?

Does New Mexico have a homestead exemption?
Most states offer some form of homestead exemption or credit that lowers the taxable value of your main home. Check with your New Mexico county assessor; you usually have to apply once after you buy.
How much house can I afford?
A common guideline is to keep your total housing payment (including taxes and insurance) under 28% of your gross monthly income, and all debt payments under 36%. Use the calculator to find a home price whose total monthly payment fits that range.
When does PMI go away?
On conventional loans you can usually request PMI removal once your balance reaches 80% of the original home value, and it is cancelled automatically at 78%. FHA loans have different mortgage insurance rules.
