How to appraise a commercial space in Mexico

Appraising a commercial space is a different exercise from appraising an apartment. The rent or sale depends less on the property's condition and more on location, foot traffic and the profitability the space can generate for the business that will occupy it. This guide explains the three methods appraisers use in Mexico, what documents to review, and how to combine criteria to reach a defensible price.

Three appraisal methods

1. Market-comparison method

The appraiser identifies operating spaces within the same commercial corridor with similar characteristics: area, frontage, depth, accessibility, number of levels. They apply homologation factors for location, traffic, age and condition, and obtain a reference price per square meter.

Example: in Polanco, spaces on Avenida Presidente Masaryk range between $130,000 MXN/m² (ground floor with direct frontage) and $70,000 MXN/m² (second floor, no direct frontage to the avenue). In San Pedro Garza García, on Vasconcelos, ranges are similar. For neighborhood corridors in Iztapalapa or Naucalpan, prices start at $20,000 MXN/m².

2. Income capitalization method

Spaces are above all investment assets. That is why the most robust method is usually to divide the net annual rent by the corridor's capitalization rate.

Value = Net annual rent / Capitalization rate

The net rent is the effective monthly rent less estimated vacancies and maintenance expenses paid by the landlord. The capitalization rate is observed in recent transactions:

• Prime corridors of CDMX, Monterrey or Guadalajara: 7%–9%.
• Secondary corridors: 9%–11%.
• Shopping plazas outside metropolitan zones: 11%–14%.

Example: a space with net rent of $480,000 MXN per year in a prime area of Polanco, with a cap rate of 8%, is worth approximately $6,000,000 MXN.

3. Cost method

Measures the replacement cost of construction less depreciation, adding the land value. It is useful for atypical properties or when there are no comparables (for example, a new industrial warehouse in Apodaca or a space with special use).

Appraisers in Mexico usually weight all three methods: 50% comparative + 40% capitalization + 10% cost is a typical mix for operating spaces.

Who can issue the appraisal

In Mexico, appraisals with tax or banking effects must be done by appraisers authorized by:

• Sociedad Hipotecaria Federal (SHF), for bank loans.
• Indaabin (Instituto de Administración y Avalúos de Bienes Nacionales), for federal properties.
• State or municipal treasuries, for ISAI or predial purposes.
• State appraiser associations (Colegio de Profesionistas, Colegio de Ingenieros).

If the appraisal is only for a private negotiation, an appraiser with professional license is enough. For a sale operation with financing, they must be registered with SHF.

Documents to have ready

• Public deed of the property.
• Predial bill and certificate of no debt for water.
• Municipal cadastral appraisal.
• Architectural plans and descriptive memorandum.
• Current lease contracts, if any.
• Account statement of maintenance fee if in a shopping plaza.
• Land-use license issued by the alcaldía.

Key variables in space valuation

• Frontage and depth: a space with 8 m of frontage and 10 m of depth is worth much more per m² than one with 4 m of frontage and 20 m of depth, even with the same total area.
• Corner vs. mid-block: a corner with double frontage can add 15%–25% to the value.
• Levels: ground floor generally rules; second floor is worth between 50% and 70% of ground floor.
• Parking: in CDMX, Guadalajara and Monterrey, having own parking spots adds measurable value.
• Land use: a space with a license for restricted use (alcohol- served food, gas station, gym) is worth more than one with limited land use.
• Pedestrian and vehicle traffic: SCT, INEGI and private firms publish traffic counts for main corridors.

Step-by-step process for an appraisal

1. Define the purpose: sale, rent, mortgage guarantee, inheritance or partnership dissolution.
2. Select the appraiser by purpose (SHF, Indaabin, state association, private appraiser).
3. Gather the property's documentation.
4. Accompany the appraiser on the visit and describe current operating flows.
5. Receive the opinion with methodology, factors and conclusions.
6. If you are going to sell, complement the appraisal with an updated comparables analysis your real-estate agent can provide.

Practical case: a space in Guadalajara

A space on Avenida Vallarta, Guadalajara, measures 120 m². It is rented at $65,000 MXN per month with a 5-year contract, indexed to INPC. The capitalization rate in the corridor is 8.5%.

Net annual rent = (65,000 × 12) − 6% vacancy − 4% expenses
               ≈ $700,000 MXN
Capitalization value = 700,000 / 0.085 ≈ $8,235,000 MXN

Comparables show a range of $7,800,000 to $8,600,000 MXN. The appraiser's conclusive value is set at $8,200,000 MXN.

Common mistakes

• Appraising a space only by m² ignoring frontage, depth and level.
• Using the municipal cadastral appraisal as the only reference for a sale: it is usually well below market value.
• Not considering the current lease contract and its terms.
• Forgetting land use: two adjacent spaces can be worth differently if one has a license for alcohol-served food.
• Not verifying maintenance debts in plazas, which transfer to the buyer.
