And even the things I do know may be incorrect.   

Sure you can suit everybody, show you paid professionals, and did your best and correct anything that was done incorrectly but if it wasn’t fraud there should be minimal consequences. 

When we pull permit for the additional bathroom, inspector delay signing due to some minor things like incorrect pipe material for the bathroom, electrical sub-panel is not up to date, central air heat certification needed, etc...

The city requires they be complete before tenants move in, correct? 

If anything in the past was done incorrectly, once they're in there for inspections, you may be obligated to fix old issues that you could have otherwise gotten away with ignoring.NJ DCA Filing - Properties that are 3-units and above require a "green card" from the NJ DCA, which requires an initial registration + inspection as well as an inspection every 5 years.

@Quandra Adams - your lender is correct and somewhat incorrect at the same time.  203k's allow for any renovation related fees- such as the HUD consultants work write-up ($400-$1000), draw inspections (up to $350 per and max of 5), title bring downs (typically about $100 per), architect (if your using one), engineering (if applicable), etc are allowed to be financed into your renovation budget. 

There is a section of the foundation that does not meet code and was poured with the forms being incorrect.

Also, laws are specific to the state you're in and Hawaii has some quirks that we mainlanders don't even think about  (like lava fields), so be sure to take any specific advice with a grain of salt.Best of luckStephanie

No, not even if you are paying all cash like some people would incorrectly say.It's entirely possible to earn a double-digit IRR on a 5-cap property. 

If you don't have to pay off the HEL, you are still 50K short but closer.Does not look like the HELOC will work unless you have another source for the ~150K (50K) or my assumptions are incorrect.
