Turnkey effect on ROI

[Ariel G.]

Hi.

How does buying a turnkey property affect your ROI vs BRRR it yourself?
From where do they take their rewards and how does that affect your ROI and risk?

How can you be sure its a good investment, because of their high motivation to sell it to you, vs an impartial adviser that will guide you trough the process of buying, taking a standard fee not related to the property? Would it be enough to do some investigation on the market value for similar properties?
