Rehab with tennent in place

[Sean Harris]

I am brand new to investing and i am still confused on the whole BRRRR strategy as far as the rehab aspect. Say I were to buy a duplex, triplex etc but there are tennents that are currently living in the units. How do i go about rehabbing those units? Obviously i don't want to kick the current tennents out while rehabbing but what other option is there? Also one more question, what are the best things to remodel to help increase value so I can refi and pull that money back out? I'm talking besides large projects such as kitchen and bathrooms. Thank you
