Searching building of unit of apartments

[Filippo Ceccagno]

Hello Everyone, 

I am new here, however, I am a very eager member and I am following your podcast regularly. I have recently found a possible partnership in London, UK. However, the deal is that I will have to find a Building of flats to rent. The company I am partnering with is a small concierge company and we are looking to rent apartments to accommodate clients from different countries coming to London for work and business trips. Has anyone of you know someone who owns 5 to 10 flats buildings that are looking to rent them all? Or if you do not know anyone do you have any tips on how I may find private landlords that are looking to rent the whole building? Also, how would you approach this? Walking by buildings and calling agencies or any website?

The area we are looking at is in Central London.

Any help will be really appreciated.

Kind Regards

Filippo
