@Jim K., I appreciate the feedback, and will do my best to answer the questions that you posed in the order you presented them. Before I begin, the biggerpockets BRRRR calculator doesn't allow for the sharing of the street address of this property, but for your aide, it is 2623 Patterson St, Pittsburgh, Pennsylvania 15203. If you happen to get better numbers and are inclined to make an offer on it, feel free, as I am only interested in attaining a better understanding of the Pittsburgh market through deal analysis, and not so much in the property itself.
1. The comps I received were from a friend of mine currently residing in Pittsburgh who also happens to be a realtor that only works with investor, especially those from out of state, as I am in California. He himself invests in Pittsburgh and has completed, and is in the process of completing, several fix-and-flips, and has multiple buy and hold properties as well. His name is Choby Siau and I would highly recommend him (Message me for his contact info). I did however fly out there and completely understand the situation when it comes to pocket neighborhoods. Choby does too, so when he gives me comps, I know they are reliable.
2. The 8 month rehab estimate came from info I was able to directly garner from speaking with my buddy Choby's own licensed contractor who has worked on several of Choby's personal properties similar to this one. The exact numbers for how much each fix would need are too extensive for this chat, but $85k is a bit high. I like to overestimate a bit to ensure I'll have some wiggle room should it take longer than anticipated. I would also look to convert this property from a 3bd-1ba to a 3bd-2ba. Also, this house was built in 1895, but most of the houses out there are at least 100 years old so it's fine.
3. Last but not least, whether an offer of $40k would or wouldn't be accepted on a $77k house makes no difference to me. As I said in the beginning, I am only looking to gain an understanding of what numbers do make sense. I have zero emotional attachment to any property whose numbers don't work, and would happily move onto the next one.
All in all, I wholeheartedly appreciate your advice. You have given me a lot to think about. I don't come across many people willing to tell it like it is. If you would like to chat further, please feel free to message me your email. I'd like to get to know more about you seeing as you appear to have more of a grasp on this market than I do.
Warmest Regards.
