Ball park estimates on a worst case renovation 3 family

[Dane McGarry]

Hello all, I am new to this and looking to start my journey in real estate investing. I am a first time home buyer that found a three family apartment with three bedroom units all the way up in Fall River Ma. This is a HUD forclosure. My offer was accepted at $215,000 on this house using a 203k loan. I plan to do a buy and hold on this house while house hacking living in the 3rd unit and renting out the other two units, garage , basement storage etc. The house seemed to be in pretty good shape aside from a few things such as foundation to be repointed a porch that is rotting to be torn down. The garage roof needs to be redone it is falling apart. When I had a plumber come to connect the systems so I could perform a home inspection he informed me that he saw a lot of problems. He recommended running my numbers having to replace all of the plumbing. ( in a comparable home same city he recently did a similar job for 40k). I am now curious on what my worst case situation cost would be if this home has to be a complete gut job. Any comparable houses I am looking at are listed around $350,000 and would still have units that are dated at that price. So I feel that the 130k difference in price would allow me to put the work into this HUD forclosure and end up with a house with brand new systems and updated units for the same price that I would be able to get into any of these other properties. Am I being realistic. Any advice or information is appreciated. Tell me what additional information I can provide in order to get better responses. Thank you in advance!!!
