Confusion on permits in new mexico (bathtubs or anything else)

[Ryan Wakabayashi]

I am a deployed military member who is looking to learn to flip houses/rent homes later. I am uncertain with some things and I am hoping to be guided in the right direction. I live in New Mexico and was looking at doing most repairs to a home myself (because I am very good with working with my hands), unfortunately I am uncertain when I require a permit. I know for the homes that I am looking at (1930s to 1960s) many of the bathrooms and kitchens will need repairs. I would like to know which repairs will require a permit/professional and any other helpful insite one may have to add about evaluating repair costs, things to watch out for that will ruin a deal, and any other useful information one may have to provide.

Thank you in advance,

Ryan
