If anyone could give me some tips on what to look for in multi-family homes for house hacking and how to run the numbers properly that would be greatly appreciated!

A good CPA will more than pay for themselves with the tips they can provide you to reduce your taxes. 

But I have seen new investors forget that tenants may leave and they don't have the capital or contracts to get renovations done to get the now vacant units in tip top shape to get the higher end of the market.  

Any tips on where to find them?

@Andy DanielsThanks for the tips!

Owning properties and making a steady cash flow to be able to have my money work for me has been a massive goal of mine and I have to start somewhere and am looking for tips, ideas, really anything that could help me start this process!

If there are pictures of it not being “broken” before move-on I’d get a handyman quote or have landlord do same to simply fix it.

Repairing something that's broken, depending on what it is, can be something they might be more likely to tell you you don't need a permit for.For example, instead of saying "I'm going to take down several walls and put new ones up" you could say, "I'm going to repair several sections of crumbling plaster by replacing the plaster with drywall, and putting in some insulation in the process" - if that's a fair description of course.It's a minor difference in framing, and might not matter, but where there's ambiguity I usually like to try to tilt things in my favor where possible 😀For tracking down the building department you could Google it or look on ripropinfo.com which is my usual launching-off point for researching properties - it has a column for the city/town website which can be helpful because sometimes towns change their sites from .us to .gov to .com or whatever (more often than you'd expect actually).

-Over $20k in water damages from a broken toilet that they proposed to fix when it was cheaper just to replace.

One valuable tip I’ve already realized is the higher-than-expected property tax on investment properties in the Indianapolis area, referenced by @Victor Tatyanin in a recent post (I was quite disappointed by this, but of course this is vitally important information!)
