IN THIS ARTICLE:

Urbanitae opens a new real estate investment opportunity: the Ondarreta project, a debt operation consisting of granting a loan for the acquisition and conversion of seven commercial units into nine tourist apartments in Alcorcón, near Madrid. Financing will open on Wednesday, October 22 at 12:00 (UTC+2).

The units are located in a standalone building at Calle Río Duero 16, just two minutes from Puerta del Sur metro station, connecting to lines 10 and 12 (Plaza de España and Metrosur). The development is particularly aimed at long-stay student accommodation, thanks to excellent connections with Rey Juan Carlos and Carlos III universities.

Nine Apartments

The loan will finance the acquisition of the commercial units and the development of nine tourist apartments, which the developer will retain as property for later operation.

The project is processed under a responsible declaration, so no construction license is required. This allows work to begin once the units are purchased, speeding up timelines and reducing associated risks. Additionally, the developer holds a planning viability certificate issued by the Alcorcón City Council for the implementation of tourist apartments.

The total estimated duration of the project is about 20 months, including construction completion and the launch of the finished units.

16.67% Return in 20 Months

Key features of the Ondarreta loan:

  • Total Loan Amount: €500,000
  • Term: 20 months
  • Interest Rate: 10% fixed annual
  • Interest Payment: due at maturity
  • Early Repayment: the developer may repay the loan at any time, guaranteeing investors a minimum payment of 15 months of interest (make whole)

Guarantees:

  • First-rank mortgage promise on the properties where the project will be developed
  • First-rank pledge promise on the shares of the special-purpose vehicle company

A Leading Manager at Urbanitae

The developer behind this opportunity is a company affiliated with Grupanxon, a group with over 20 years of experience in real estate and a long history of collaboration with Urbanitae.

This will be the 18th project we develop with Grupanxon, a manager well-known among our investor base. To date, 13 projects have been successfully returned, with an average IRR close to 15%.

Due to the trust and mutual knowledge built over the years, no webinar will be held on this occasion. However, as always, our team is available to answer any questions via contacto@urbanitae.com or by phone at (+34) 911 23 25 22.

This video details the project.
