Personally a cash-out refi could help me get more quickly into all-cash BRRRs or a REI venture in Spain, however I don't know to what extent this is at the expense of rental cash flows, and what is the wiser decision long term.I've combed through posts online and looked for Excel templates to run some calcs and get a sense, but nothing really filled the void...
