Quote from @Robyn Henderson: My family's 3 unit prewar building in Brooklyn recently had plumbing issues and I'm debating renovating each of the bathrooms.

You want to build a relationship.  

I look at foreclosures.comOut of the 3 stages I am definitely not ready for an auctionpreclosure / short sales:- I need to research how to take over a deed / title- need to prepare how to do door knocking (I have a sales background and feel confident in dealing with an emotional conversation about someone’s home) - there IS a window of like 4 weeks that I need to prepare for (have my finances in order) to then bid before it goes to auction?

In my 30 years doing this I’ve found that as long as you address each issue that comes up properly and do the repair needed to bring that part of the building up to current code then you will be fine.

I have refinanced (rarely mind you as there are costs that take years to recoup on a refi) and am happy to see equity build as the mortgage shrinks.

You need to simplify, not add more debt.Focus on education and building reserves.

Here are some of its vitals:- Zestimate: $345K (I know this is typically 10% or so high)- Last Sold: 8/2021 for $281K- Roughly 1400 sqft- Some cosmetic work needed- $25K left on solar loan- The home was build in 2004 and it looks like it has the original AC unit, so I am assuming that needs to be replaced too. - 2 story house with very small rooms and and 2 steps down, imminently as you enter the front door.- Gated community and in a reasonable HOA. - The home is 2 payments behind and already got a letter from the lender about future foreclose.

I like his points about building a “team” and not actually asking people to be “on my team”.

Without actually building the 3rd unit, would this new triplex eligibility increase my property's value? 

BP has built a great selection, all of them worth reading and that will help you build foundational knowledge.To answer this one: the words from old school investor Dolf De Roos "seldom sell" and you will find a lot of post on BP from people who regret selling properties in the past.
