Rehabbing 6 unit: Little by Little

[Maria Cortez]

My parents own a 6 unit building (3 floors). The building is over 120 yrs old. It needs serious updates. I'm thinking a total gut (i.e. electrical, plumbing, tuckpointing, etc). They cannot afford and do not have the energy to complete such an endeavor. I would like to help them so that they can have a nice place to live in comfort as well as my disabled brother who lives with them. I have never done anything like this. Is it possible to renovate one unit at a time?
