Please let me know if this sounds correct.

I don't know what they are but unless there's something in the city that requires that kind of notice, it sounds excessive to me.

This sounds like you need an attorney to do this.

And what is your price point, and it sounds as if you're OK with slight to moderate rehab, is that correct?

Sound right? 

I had to replace doors, carpets, repaint.

What you describe sounds a little like a BRRRR (Buy Rehab Rent Refinance Repeat). 

The licensed versions sold at big box stores are not the same quality and break down quickly and rarely have replacement parts.

If you are purchasing that MF property for $1 mil then you can use the 3 units as your replacment for the 1031 exchange ($750K of value) and live in the last unit ($250K of value).An awesome way to house hack your way up!!! 

I realize I don't have the actual NOI, but that price sounds super high for the gross income you're stating in your narrative.
