Hi to everyone,I would like to ask that ,my banks in my country (Greece) are unable to provide refinance options for the BRRRR method (Buy, Rehab, Rent, Refinance, Repeat), what alternative realistic strategies can I consider for implementing this investment approach?

I would be very careful in working with a 1031 Exchange Qualified Intermediary that provides ("sells"0 replacement property solutions as part of their services. 

Partner Driven provided 100% of the funding, including the $45,000 purchase price and $92,049 renovation budget.
