NM lawyer recommendation & question

[Emily Rolando]

Hi there, I have 3 duplexes in Aztec NM, and haven’t found a real estate lawyer who will double check my lease. I know I can use a generic state specific one a d be done with it it I’d like to use my own preferably. I also have a few pressing tenant/lease renewal questions for them or maybe someone on here with NM rental law understanding better than mine. See question and extra info below. TIA

Can I increase rent for one unit because 3 people are living in a 1 bedroom while not doing that in my other units?
extra info: The 3 people are two adults (mom and adult son) and 1 minor (moms daughter/sons sister). I’m not going to kick them out due to potential discrimination against familial status and they were inherited tenants who pay and want to stay. But I’d like to increase rent when lease is up and hand over all utilities to them. I’m not going to increase rent on anyone else however (most are month to month). Would this be considered discrimination? I can see it both ways and the landlord in me sees additional wear and tear, utility use etc that I’ll end up paying for if I don’t.
