I've seen this video, and watched quite a few of his videos actually. (I'm going to derail the thread a bit now.) In fact, it seems there are a ton of people doing what he does - see vlogs like Pierre Ollier, Olivier Seban, Esprit Riche, and many many others, all inspired by Robert Kiyosaki. They are all supposedly "millionnaires" owning a ton of properties, but out of the goodness of their hearts, they are selling "training courses" so you can become a millionaire too. The whole premise seems suspicious, but having said that, a lot of the advice they give in their free videos does seem reasonable. They all sell more or less the same formula: maximize your yield and minimize your taxes by finding old apartments in bad shape, negotiate hard, renovate, and rent them out as "LMNP" (french term for a long term furnished rental), or sometimes short term via AirBnB and the like. Claim back your renovation costs from taxes, deduct depreciation, and you are able to rent your property tax-free for great many years. Together with other yield-enhancing tips (split large apartments into smaller units, etc) they claim that you can achieve rental yields in excess of 10% (usually in small-to-medium towns), often claiming outrageous yields of 15-20% even, which means the investment is entirely self-financing: you put down a minimal amount, like 10%, or even nothing, and then the rent more than covers the mortgage. Rinse and repeat until you are rich. It's hard to separate fact from fiction in all this though - the tips themselves are generally good, but can you really "create" these 10%+ yielding properties in a location with reasonable prospects, good tenants that pay rent, etc? I don't know the answer to this (but I'm curious), though it seems some people do succeed... maybe.
