If anyone has any suggestions, that would be greatly appreciated! 

I would love to hear more, and dive deeper into suggestions with a little more info.  

Now my main issue is I need a fire detection system in a enclosed back porch that leads up to all three floors, but I don't know what's the minimum I would need to be compliant or that the fire marshall is suggesting what he wants or recommends.

I literally laughed through the phone at his suggestion, because I was broke, in debt, and in every way and unqualified borrower, and the lending environment in 2012 was probably stricter than it had been since the invention of the 30yr mortgage.

What other loans might you suggest for House hacking? 

See if you can get a copy of The Millionnaire Real Estate Investor by Keller.The Slight Edge and Atomic Habits too.Awesome board with many smart people having own suggestions and ideas to grow wealth!!

Would highly suggest getting a subscription and making sure you look at properties that match your condo and see what they're making each year.

Though my response might help others, common courtesy suggests you thank those who took the time to answer you.

But I would suggest exploring all options to make sure you are getting the best rate and terms.

Any suggestions or recommendations out there for best rate HELOC (not 2nd mortgage).
