Hello Sam!
Here's what the General Sign Regulations state for the city of Albuquerque (Part 3 § 14-16-3-5(C)(4)(b) - Real Estate Signs):
1. a. One temporary real estate sign located on the property it refers to shall be allowed for each street frontage of a developed premises or undeveloped lot of less than two acres. Signs shall be removed within seven days of sale or complete leasing.
b. In residential zones, the signs shall not exceed four square feet in area including name identification riders. An additional add-on sign area of one-half square foot indicating that the property has been sold or leased is permitted. In nonresidential zones, the signs shall not exceed 16 square feet in area.
2. One temporary real estate sign not exceeding 24 square feet in area and located on the property it refers to shall be allowed for each lot two acres or over. If the lot has multiple frontage, one additional sign not exceeding 24 square feet in area shall be allowed on the property, to be placed facing the additional frontage. Under no circumstances shall more than two sign units be permitted on the lot. Signs shall be removed within seven days of sale or complete leasing.
3. Temporary real estate directional signs not exceeding three square feet in area, three feet in height, and four in number, showing a directional arrow and placed on private property may be permitted on approach routes to an open house.

There shall be no violation of the clear sight triangle at any street intersection. Signs shall not be allowed where the sign is directly across the street from or adjacent to the lot line of a residential zone.
- Timing: Signs shall not be displayed prior to the date of recording of the plat, and shall be removed upon completion of the project.

Hope this helps and as @Adan Gonzalez stated, you might also need to check with your HOA regulations if the property is located within a HOA zone. Good luck! -DVICENTI-
